The chemical properties in seawater make finding the right pump more difficult than when pumping with fresh water. Not only do these pumps have to withstand the damage from floating sand, but saltwater corrodes the metals commonly used in pump manufacturing. When looking for pumps for marine applications, especially at sea, there are certain materials that prevent rust and other damage. Read more to see what our team thinks are the best seawater pump material options.
Ideal Characteristics for Seawater Pump Material
The key quality in looking for a seawater pump is how resistant the materials of construction are to corrosive material. The amount of salt present in seawater corrodes metal five times faster than fresh water. Salt that is present in the air, corrodes metal ten times faster than that. This is due to the chemical properties of salt in the water; ions float freely in salt water, and these ions then force metals into a more neutral (or corroded) state. In a similar vein, floating sand in the water poses a threat of eroding the wetted interiors of pumps- especially in high-velocity applications.
In addition to corrosion resistance, the right material should also be able to handle fluctuating temperatures, especially for heating & cooling applications onboard. Submarines or other submersible applications will also require materials strong enough to withstand stress from high-pressure usage. Another characteristic of a good seawater pump material is how durable it is. Being out at sea limits the tools available to repair broken pumps, and removes the opportunity to take these pumps to the nearest repair shop until after the ship is docked.
Bronze Pumps
Pro: Bronze material is the Marine industry standard for seawater pumps. This material is corrosive-resistant and works well with fluctuations in water temperature. These properties make bronze an excellent choice for either bilge pumps or onboard heating & cooling pumps.
Con: While bronze pumps are popular for marine applications, this material does not have the same strength as stainless steel or other harder metals. Because of this weakness, a pump made out of bronze will be less durable than a pump made of cast iron, steel, or other metals. Additionally, bronze is more expensive than other seawater pump materials.
Oberdorfer & MP Pump specializes in bronze pumps for marine & heavy-duty chemical applications. Oberdorfer offers gear & centrifugal pump options, while MP offers its bronze pumps in centrifugal styles only.
304 and 316 Stainless Steel
Pro: While there are many variations of stainless steel, the most common type used for pumps is either 304 or 316 stainless steel. These are common materials used in industrial pumps and are a popular choice in food manufacturing due to the surfaces’ clean-in-place capabilities. Stainless steel has excellent strength and withstands high-temperature applications very well. Another benefit to using stainless steel as a seawater pump material is the durability of the pump will last a long time when compared to other comparable materials.
Con: The drawback to using either version of stainless steel is the corrosion resistance. 304 and 316 are moderately resistant to corrosion, however, they are prone to ‘crevice’ corrosion, meaning in the small areas near gaskets and other hard-to-reach areas. This can also lead to an increased risk of stress cracking throughout the pump as well.
When it comes to Marine industry pumps, Blackmer offers top-of-the-line stainless steel options through its sliding vane, screw, and gear pumps. Blackmer’s main focus is providing military-grade solutions as opposed to other pump vendors. This brand is an excellent choice when looking for durability in a seawater pump. For heating and cooling applications as well as wastewater treatment onboard, Grundfos’s CR series pump is made entirely out of stainless steel for high-temperature resistance and efficient pumping.
Duplex Stainless Steel (CD4MCu)
Pro: While 304 or 316 is the most common version of stainless steel, duplex stainless steel is another variation that offers better corrosive resistance than other types of steel. The difference between the two is 304 steel contains 18% chromium and 8% nickel with a maximum of .08% carbon. Duplex stainless steel, also referred to as CD4MCu, contains approximately 25% chromium, 5% nickel, and .04% carbon; it also includes copper, manganese, and silicon. The result is higher corrosion resistance & more durable material when compared to 304 or 316 stainless steel.
Con: The biggest drawback to choosing duplex stainless steel versus a 304 stainless steel is the price associated with the material.
Blackmer offers CD4MCu options for its centrifugal pumps. Griswold’s 811SP series pumps also offer CD4MCu material rather than standard stainless steel such as the 811 series.
Fiberglass
Pro: The last option for seawater pump material we offer is the non-metallic fiberglass option. Fiberglass is an excellent choice for corrosive substances like seawater or chemical applications. Fybroc specializes in making fiberglass-reinforced polymer (FRP) pumps, and they are a popular choice for fisheries and aquariums.
Con: The main drawback of using fiberglass as opposed to other seawater pump materials is that fiberglass is more fragile than metals like stainless steel or even bronze.

When working in sanitary or hygienic applications like Food & Beverage or Semiconductor manufacturing, it is vital to maintain strict air purity standards, especially having oil free air. Oil vapor in compressed air can be tied to diminished product quality as well as health concerns for both employees and customers alike. Depending on the industry, exceeding the limits of oil vapor in air can mean loss of product, hefty fines, or even a pause in production altogether until the problem is resolved. The International Standards Organization (ISO) designed parameters for compressed air to determine the quality of compressed air, ranging from class 0 to class 6.
Why ISO Class 0 Status Matters
ISO classification 8531-1 uses three different metrics to determine the quality of compressed air, sorted by the types of contaminants. The difference between these options is through the displayed ISO class. These classifications can be split up depending on how they meet each standard or by meeting all three thresholds at once. So one compressor could be Class 1, but another might be Class 1 for only one of the criteria, and Class 2 or 3 for the others. ISO sets Class 0, the highest level of air purity, differently from the other classes. Manufacturers and end-users set standards for Class 0 Air, however, these standards must be more stringent than Class 1’s parameters.
The first measurement is the Solid Particle Maximum or number of particles per million in the compressed air. Proper filtration protects against dirt, dust, and other solids present in compressed air. The second measurement is the Pressure Dew Point, which relates to the amount of water vapor present in the compressed air. The lower the dew point, the less moisture is available for bacteria to grow. The final metric for air purity measures the presence of lubricant or oil vapor within the air. Oil vapor, especially non-food grade lubricants, contaminates the compressed air encountered.
This third metric, the oil vapor has historically been difficult for facilities to monitor. Typically, facilities need to coordinate with outside laboratories certified by the FDA and provide samples of the compressed air. This process can be time-consuming, and with severe consequences for a failing grade, ensuring oil free air is truly oil free is vital. While there are many ways to achieve oil free air, here are three methods we have found to be effective.
1. Oil Free Air Compressors
The easiest way to eliminate oil in your compressed air system is to start at the source. An oil free air compressor still has oil lubricating the machine, but its design does not allow oil vapor to interact with the air at all.
Sullair’s oil free DSP rotary screw compressor takes oil free to a new level. The DSP is classified as Class 0 air, meaning the oil vapor present in the air is less than .01 mg/m3. However, Sullair took this one step further by utilizing third-party certification to offer not just Class 0 air, but certified Class 0 air. DSP compressors achieve this through technology like its patented oil mist remover, the drain separator, and an easily accessible oil filter. As an added benefit, the oil mist remover recycles the compressor oil captured, reducing the amount of compressor fluid needed.
2. Air Treatment
Using the right air treatment options, facilities can be more secure in the fact their air is oil free. Pairing oil free compressors & air filtration together decreases the chances of oil present in production. In the unlikely event that an oil free machine accidentally releases more oil than an oil mist remover allows, the air filtration is another barrier to prevent oil from leaking through. Air dryers can also have a similar effect by reducing the oil’s temperature enough for condensation to occur. From there, the filtration collects the oil so it can be safely removed.
Parker provides top-of-the-line filtration such as its Oil-X OVR Oil Vapor Reduction Filters. Similar products use loose carbon to trap oil vapor, however, Parker sets the Oil-X apart with the extruded aluminum design, making it both smaller and lighter. With this trade-off, the Oil-X uses compact activated carbon cartridges to maximize packing density.
3. In-House Oil Vapor Monitoring
While oil vapor testing usually requires sending a sample to a certified laboratory, this is no longer the only solution. Beko Technologies offers a one-of-a-kind in-house oil vapor monitoring solution, the Metpoint OCV. The Metpoint OCV connects to the compressed air system and takes two samples every sixty seconds. The first sample is purified and compared against the unaltered sample with detection for up to .001 mg/m3 oil vapor content. When the set threshold is met or exceeded, the OCV then sets off an alarm. Alternatively, the OCV can send alerts directly to email using an optional IoT feature.

Water usage and water conservation are becoming increasingly important topics for manufacturers. Reducing water waste can mean thousands of dollars in both water and energy expenses. One of our flagship vendors, Grundfos, specializes in water pumps that allow for better water efficiency, while still maintaining or even increasing the amount of product made.
Grundfos Pumps for Industrial Applications
Grundfos specializes in water pumps in a variety of styles to best match the spaces and needs of a facility. Our customers choose Grundfos water pumps because of the wide variety of tasks they can accomplish.
As an added benefit, this brand prides itself on its energy and water-saving pump technology and has pledged to help reduce water waste worldwide. Some case studies have shown up to a 20% decrease in water consumption at some facilities by implementing process-water recycling measures. Grundfos accomplishes this by reducing leaking through automation and its proportional pressure control during off-peak hours. Additionally, this control in pressure reduces the amount of water hammer in the system, which in-turn protects downstream equipment from premature failure.
In addition to these world-renowned water pumps, Grundfos also offers sensors & controllers to increase the capabilities of the pumping systems they create. This automation frees up facility staff to better oversee the entire production line.
Process Applications
Grundfos offers water pumps such as the SP series, CR series, & NB series to act as intake pumps. The SP series of submersible pumps is best for groundwater uses, while the NB series offers single-stage end-suction pumps for surface or tap water. Grundfos’s CR series serves as the flagship multi-stage pump and works for a wide range of applications throughout a facility.
In addition to being able to transfer process liquids, Grundfos water pumps work well supporting machining applications as well as for sanitizing and cleaning processes. Grundfos offers solutions for clean-in-place needs, such as food production facilities, as well as solutions for conveyors & pipes. For additional sanitization, Grundfos even offers solutions for pasteurization & bottle washing, both of which are important features for dairies and breweries.
Temperature Control Applications
Grundfos water pumps can play a vital role in temperature management and have solutions for both increasing and decreasing temperatures to maintain the desired outcome. Whether working outside a facility in a cooling tower, or inside a facility, either working as chiller pumps or circulating pumps, a pump from Grundfos will go a long way. For a more in-depth look at how Grundfos water pumps work with cooling systems, click here.

One of the critical problems wineries face is preventing their wines from coming into contact with oxygen. Wine oxidation means contamination and running the risk of throwing out tens of thousands of dollars worth of product. While there are ways to save the wine afterward, these measures siphon extra time and money from the rest of production. The easiest way to prevent wine oxidation is to minimize the risk of oxygen exposure, especially where the risk is highest: at the pump. Here are seven features to look for in pumps to reduce the risk of wine oxidation and improve the quality of your wine.
Self-priming
Self-priming means that a pump can run dry and create a vacuum to pull in the liquid, even if it’s at a lower level than the pump. Non-self-priming pumps typically require a flooded suction, where the fluid level stays above the centerline of the pump, to prevent cavitation as tank levels lower. To prime a REAL self-priming pump, there’s nothing else to do but turn on the pump. A self-priming pump reduces the number of steps to follow during daily startup and continues to pump even when the fluid in the tank drops below the pump suction. Self-priming pumps reduce the risk of cavitation and the entrainment of potential air pockets, which can contribute to wine oxidation.
Shear sensitivity
Whether working as a regular wine pump or a must pump, a pump with shear sensitivity will better maintain the quality of the wine. Shear sensitivity, alternatively known as low shear rate, refers to a pump’s ability to maintain the integrity of liquids that change in viscosity depending on the force applied. High shear rates in a pump will damage the fibers and molecules that contribute to the flavors in wine. A pump with a low shear rate will have a much gentler impact on any fluids it pumps.
Mobility
Every second counts during the harvest, with some days lasting ‘until the job gets done.’ In most pumping applications, a facility places pumps in fixed locations with piping moving liquid where it needs to go. However, for wineries, it is the other way around. These pumps need to transfer wines to and from barrels, tanks, and bottles, and depending on the time of year, the locations of each can dramatically change. The easier it is for a cellar worker to transfer wine from one place to another, the more time they will save overall. This means more wine with less hassle and a lower cost per bottle.
Flow Reversal
Similar to mobility, having a pump that can reverse the flow entirely can greatly benefit wineries. A pump with flow-reversing capabilities cuts down on the number of pump carts a winery needs, and in the event of a mistake or emergency, a cellar worker does not need to track down a second pump cart to move the wine back to where it needs to be. In stationary pumping systems, less piping is required for bi-directional flows. Simply reverse the pump to reduce installation costs and save time.
Seal-free, leak-free
Wineries work with distinct seasons rather than a standardized year-round output. Equipment going down during harvest can devastate the entire production line. Mechanical seals require the pump to be taken off the production line during removal and installation. The alternative to seals, pump packing, does not stop leaks from a pump. In fact, packing by design must leak to stay properly lubricated. Finding a pump that does not require a seal and will minimize leakage is essential for reducing the risk of downtime during the peak of production and reducing the loss of product due to failed seals and packing.
Clean-in-Place Capability
All sanitary pumps must maintain strict hygienic standards to comply with FDA regulations. Instead of repeatedly taking the pumps apart every night, sanitary pumps often come with clean-in-place designs. A clean-in-place design allows workers to feed the cleaning solution through the pump without dismantling it every night.
Line-Stripping
One issue that wineries often face is leftover juice or wine remaining in the piping after the pump has been turned off. This remaining wine, if recovered, is usually off-color and diminished quality- due to wine oxidation from the disconnecting pipes. If not recovered, it is flushed with the cleaning solution nightly. The solution to both problems is a feature called ‘line stripping.’ Line stripping refers to a pump’s ability to pull the remaining fluid from the input pipes before turning the pump off for cleaning. A pump with line stripping capability will not only prevent wine oxidation, but it will also allow for product recovery and dramatically reduce waste.
Mouvex Pumps 
This year, Northwest Pump announced a master distribution agreement with PSG to offer Mouvex and two other pump brands on the West Coast. Mouvex offers eccentric disc pumps designed in the heart of wine country in Auxerre, France, specifically to meet the needs of wineries. These eccentric disc pumps come with the following features:
- Self-priming design
- Shear-sensitive pumping
- Mobility options like pump carts or fixed skids
- Flow reversal add-on valve options
- Seal-free & leak-free design
- Line stripping
- Clean-in-place capabilities
Mouvex’s line stripping procedures are automatic, and the clean-in-place process is as simple as a turn of the valve. Additionally, certain Mouvex pumps offer dry-run capability, which protects pumps from heat damage when the pump runs without liquid. Lastly, Mouvex offers precise volume metering options to track how much wine is produced daily.
Next Steps

The simplest way to waste your compressed air is by ignoring compressed air piping. The wrong air piping equipment connecting your compressor to the rest of your facility can mean thousands of dollars in lost utilities, and even safety hazards- depending on the type of piping used. Common issues with piping include undersized pipes, layout inefficiencies, air leaks, and the material making up the pipe itself. Here are a few factors to consider when looking at your compressed air system’s piping.
Layout Inefficiencies
Inefficient piping layouts are the fastest way to reduce the pressure of compressed air. As the air travels through the piping to its destination, each turn in the pipe will reduce the momentum of the air. Additionally, the farther the air travels from the compressor, the likelihood of this pressure drop increases.
The best solution to this inefficiency is preventing it before the air piping is laid down. Installations can be costly and time consuming, and that is before considering potentially turning off air power to production. When considering where the piping should be installed, look for the straightest paths from the compressor to where it needs to be on the production line. Our installation team always looks to create a ‘loop’ in the piping to evenly distribute air to all the equipment.
Undersized Air Piping
The diameter of the piping adds another factor into pressure loss, and this can also stem from layout inefficiencies as well. With undersized pipes, the problem is maintaining the pressure needed at the end of the pipe while keeping the air flowing at the right speed.
This is another issue that is better solved before it happens than fixing it later. Before picking out the size of the pipe, find these specifications for your compressor system:
- Maximum CFM (cubic feet per minute)
- Minimum operating pressure of the compressor system
- Length of the pipe to be used
- Interior diameter measurements of the pipe itself (for aluminum pipes only)
Air Piping Material
Compressed air pipe is either metal or plastic. Metal pipe materials are typically steel, aluminum, or copper, and the joints for these pipes come in a wider variety of metals. Plastic piping materials can include PVC and CPVC, as well as ABS, PE, and high-density polyethylene. Northwest Pump advises against using plastic piping in compressor systems, especially PVC piping, as PVC can be a safety hazard. Additionally, depending on the kind of plastic used, the pipes can deteriorate when interacting with certain kinds of lubricant oil particulate in the compressed air.
Air Leaks
Air leaks can waste up to 30% of a compressor’s energy if left unchecked. They also contribute to reduced air tool functionality, which then lowers production. Worst of all, an air leak can shorten the lifespan of equipment in the compressor system, leaving a facility to replace its compressor far sooner than expected. Leaks typically occur in the couplings, joints, valves, etc; any pipe ending can be at risk of leaking. Stopping these leaks is not the challenge, the solution for a leak often requires tightening a valve or replacing faulty equipment. The issue with air leaks is finding them before they cause damage. Air leaks are not visible to the naked eye, and not all hissing from the leaks will be heard above the noise level that a working facility offers.
Regular maintenance on a compressor system will be able to clue plant managers and maintenance staff in case of leaks. If there are concerns about air leaks, an air audit can identify weaknesses in a compressed air system.
Champion Quick-Lock Tubing
For premier compressed air piping, Northwest Pump uses Champion’s Quick Lock Tubing. This air piping uses non-corrosive aluminum, meaning no rust or deterioration from oil usage. Using aluminum over other metals also means lightweight durability, these pipes can be easily suspended on or near ceilings for simple layout design. Champion designed these pipes for fast, easy installation, no specialization in welding or complicated tools required.
Northwest Pump
Northwest Pump offers both Champion Quick-Lock Tubing and a team of engineers specializing in compressed air systems. This team works both with our sales team & our service division to make sure all applications, new or current, run as advertised.
For more information on air piping equipment for your facility, reach out to your nearest Northwest Pump by phone or email through our locations page.
Our industrial service division has compressor technicians who handle anything from compressor system installations to routine maintenance to even emergency service calls. They are vendor certified by top brands such as Sullair & Gardner Denver, ensuring top-quality service for your equipment.

In applications such as poultry or meat processing, where fresh meat is abundant, maintaining a sterile environment is critical. One of the solutions for preventing contamination is utilizing a vacuum pump to seal the meat before it loses its freshness. Here is everything you need to know about vacuum pumps for meat applications.
How does a vacuum pump work?
The principle behind all vacuum pumps is creating areas with low or no pressure within the chambers of the pump. From there, the gas within a contained area will try to fill what space remains until there is no gas left. These pumps operate much more like air compressors, and often use similar techniques.
Why Use a Vacuum Pump for Meat Applications?
Beyond sealing in the freshness, facilities can use vacuum pumps in a variety of applications throughout the production line. These pumps can remove the waste byproducts that might easily damage other pumps and even transport unusable parts to collection areas. Additionally, vacuum pumps offer easy transportation & packaging solutions. This reduces the mess and hassle that facilities can typically encounter with waste or even end products. Lastly, vacuum pumps can assist with marinating, tumbling, breading end products to maintain the right colors, flavors, and textures of the meat.
Our Vacuum Pump Products
Northwest Pump is proud to represent Atlas Copco’s vacuum pumps, especially when working with meat or poultry processing applications. Atlas Copco’s catalogue of vacuum pumps offers oil-sealed, liquid-ring, and dry vacuum pumps in both fixed and variable speed drives.
Whether dealing with evisceration or packaging & transporting meat from beef to pork, we recommend their rotary screw GHS series vacuum pumps. These durable pumps work well in the harsher, humid environments that these facilities tend to be. Its compact, simple design also means that these pumps will not take up more space than absolutely necessary.
For applications that deal more with processing poultry specifically, we recommend liquid ring vacuum pumps from Atlas Copco. These products will withstand the byproducts that could harm other types of vacuum pumps, in addition to working better in the harsher, humid environments that these facilities tend to be. For packaging and transportation applications, we recommend looking into vacuum pumps with variable speed drives to better control energy outputs and match demand as needed.

When it comes to food production, there are strict standards during the manufacturing process to maintain safety standards. With smooth internal surfaces & ease of cleaning, sanitary pumps meet these requirements to protect against bacteria and other contaminants. Northwest Pump offers several sanitary pump options for many different applications, whether it be for a thick yogurt slurry or freshly pressed oil.
Do all pumps in a plant need to be sanitary pumps?
No, not all pumps in a food production plant need to be sanitary. A sanitary pump is only necessary when it is in direct contact with food products. Grundfos, for example, does not offer sanitary pumps. What it offers instead is pressure-boosting equipment as well as pumps to clean out the sanitary equipment already present in a facility.
What makes equipment sanitary?
3-A symbol from the International Association of Milk, Food, and Environmental Standards
The FDA regulates Food Contact Substances (FCS) ranging from the pumping equipment processing the food, to the coverings on an at-home coffee machine. The key feature of sanitary equipment is a smooth surface that can be easily cleaned. Manufacturers of sanitary pumps can offer easily disassembled pumps to increase the ease of cleaning, depending on the brand. A sanitary pump will typically be made of stainless steel 316A, or alternatively will be made of a non-porous plastic. The International Association of Milk, Food, & Environmental Standards also has a symbol called 3A to show when a pump meets these classifications. This and the FDA logos will appear on pump literature when the product meets these requirements.
Are sanitary & hygienic the same thing?
The main difference between hygienic and sanitary equipment is in their applications. The FDA classification for sanitary pumps must meet higher standards for consumer product manufacturing. Hygienic pumps on the other hand, are for high-volume transfer applications for food & beverage, cosmetics, and even pharmaceutical processing.
Our Sanitary Products
Northwest Pump offers sanitary & hygienic pumps for a variety of applications. Our main vendor for sanitary pump equipment is PSG, a Dover Company, through its Wilden, Mouvex, and Abaque brands. We now also offer vacuum pumps through Atlas Copco, for canning and other sanitary applications. In addition to these pumps, Northwest Pump now offers food-grade valves, fittings, and other ancillary pumping equipment through Dixon Valve & Fitting. For food-grade lubricants, we have partnered with A.W. Chesterton Company. Finally, for food-safe compressed air, Northwest Pump offers oil-free compressors through Sullair.

Seventeen years ago, Northwest Pump made the jump to become an employee-owned company. Since this decision, we have seen many benefits for our employees, our customers, and the communities surrounding our eighteen different branches. While there are many characteristics of employee ownership, we have found the five most significant qualities. Any co-owner at Northwest Pump will have these five characteristics: Outreaching, Wise, Neighborly, Excellent, & Responsible- or OWNER, for short.
O – Outreach
Even before employee ownership began in 2006, Northwest Pump already participated in charitable activities in the communities we live in. For over fifty years, Northwest Pump has worked with several charities to donate to families in need in December. Since becoming an employee-owned company, Northwest Pump has expanded our efforts to give back to our communities. We have proudly worked with organizations such as Best Buddies, Habitat for Humanity, Sleep in Heavenly Peace, and many more. All eighteen branches also participate in an annual food drive to local food banks in their areas.
W – Wise
One of Northwest Pump’s core values is self-improvement- the ability to seek out new learning opportunities and challenge oneself to be better. Our co-owners are always looking for ways to grow and share their knowledge and expertise with each other.
Because Northwest Pump provides a wide variety of industrial & petroleum equipment, it would be difficult for one person to understand all of the complexities of both divisions. However, what our teams focus on is having a reliable network of experts who have extensive information about a particular brand or product category. Our collaborative culture allows for this even when the expert is not associated with a particular branch or division.
N – Neighborly
The biggest feature of being an employee-owned company is the neighborly culture here at Northwest Pump. Our most common response when co-owners are asked about why they like working at NWP is the company culture. Our teams are not just checking emails to carry on with their day, they are ready to jump in whenever and wherever a problem needs to be solved. If it needs to be handled by another division, department, or branch, we work together to get the job done.
We have a team called Employee Ownership Team to help maintain the company culture. The team is responsible for leading conversations on how the ownership works, organizing conversations around customer service & improving the company, and leading the various activities like our annual Halloween party and the food drives.
E – Excellent
Our motto at Northwest Pump is customer service is our business. At the heart of every project, we focus primarily on the needs of our customers. We strive to see every project through the eyes of our customers and do what we can when we can to find the necessary solution the first time around. We have prided ourselves on providing excellent customer service for more than 60 years.

With 2023 approaching, let’s take a look back at some petroleum highlights from this past year. Northwest Pump attended a variety of trade shows and events, added a new vendor, and celebrated a number of well-deserved promotions and retirements.
Retirement and Promotions
Jeff Kelly
After 35 years of being with NWP, Bill Mathews will be retiring at the end of this year. Bill is the Petroleum Sales Manager for our Oregon, Eastern Washington, and Boise, ID branches. We thank Bill for all of his efforts and commitment to those he has worked with.
We are excited to announce that Jeff Kelly, who has been with NWP in Outside Petroleum Sales for 25 years with NWP will be taking Bill’s position. We fully trust Jeff will bring some exciting new ideas and continued commitment to his new position starting January 1st.
Scott Tracy
We would also like to announce that Scott Tracy has been promoted to the position of Vice President- Petroleum Corporate Sales Manager. Since joining Northwest Pump in August of 2000, Scott Tracy has been an integral part of NWP’s growth. Scott has worked hard in building a fantastic team of sales and operations in California. When Scott joined NWP, we only had one California office in San Diego. He has helped build a fantastic team of committed people in Anaheim, Glendale, Sacramento, Fremont, Fresno, and most recently, Valencia. Congratulations, Scott! We look forward to having him as the head of our Petroleum Division.
New Vendor Addition
This year, we added Red E as a new vendor. We made sure to create an EV team that’s been focusing on learning and understanding the new marketplace so we can attend to every customer’s needs. Northwest Pump is really excited about the electric charging initiative and look forward to the coming 2023 year.
About Red E
Red E is an EV charging network designed to make charging easy and available when you need it, where you need it. Red E was designed specifically around the needs of the fueling industry and municipalities. The Red E network delivers fast, convenient electric vehicle charging- right off the highway and in the heart of your favorite cities.
Chevron Tank Install
These 12,000-gallon and 14,000-gallon tanks were installed for a customer in Richmond, CA. These Xerxes underground tanks are an excellent solution because they are corrosion-resistant, both inside and out. To meet the needs of our customers, Xerxes offers several fiberglass tank options for a variety of applications and requirements.
At Northwest Pump, we highly encourage anyone who needs a tank to plan ahead so there is no disappointment when it is time to install your tank.
New Features For The Encore 700 S
In September 2022, Gilbarco-Veeder Root announced the release of two new premium features for the Encore 700 Series: 6-Grade Select option and the 15.6′ touchscreen. These features are designed to provide convenience store operators with enhanced flexibility and an improved customer experience.
The 6-Grade Select empowers retailers to leverage those trends by enhancing their own blending strategies. The 6-Grade Select allows retailers to blend any two of four inlets, with up to four hoses and six fuel grades at the same fueling position- allowing the most fuel flexibility possible.
The other new feature- is a 15.6′ touchscreen that provides a next-generation user interface, which maintains the familiar Encore experience that most fuel consumers know and regularly use. The touchscreen interface eliminates the need for softkeys, creating a modern feel that younger consumers expect.
Trade-Shows & Events
PFCS
Our California Sales Team attended the Pacific Fuels & Convenience Summit in San Diego. The event was a huge success, with several good customers in attendance. Thanks to our booth crew, led by John Lees, and our sales roadies. And another thank you to our out-of-town visitors, Bob Mathews, Mike Meyer, Jim Moran, Katie Hughes, and Ruthie Carlo.
APMA
We had the pleasure again of being one of the major sponsors at the annual APMA Scholarship Fund golf tournament. This is the major fundraising event for the scholarship fund and all those that participated seemed to have a great time. Over $80,000 was raised to go to the scholarship fund. Last year, APMA gave out twelve scholarships. Northwest Pump sponsored the “take a shot” hole this year. Players could shoot their ball with an air cannon to the green. It was a great time for all for a very good cause.
Hawaii Trade Show
In May, we finally held our long-awaited Hawaii Tradeshow and Customer Appreciation after having to postpone our event a number of times. It was nice to gather with customers and vendors. We have already received positive feedback from customers! Some customers, who were unable to attend because of conflicting engagements (like high school graduations), heard about our reception from others and have already asked when we plan to have another one.
This year, to supplement our tradeshow, we wanted to show our aloha to the vendors and sales representatives by hosting a traditional backyard barbeque (Hawaiian pa’ina). We were able to stake out a great spot at the local beach park next to the hotel. Overall, everyone had a great time networking and gathering information on products from our many supportive vendors.
Looking Ahead To 2023
We appreciate the support we have received from our customers, vendors, and employees over the past year. We are excited about 2023 and wish you all the best as we enter into the new year!
