Gardner Denver Pumps

The ChemFlo® series of pumps are designed to be applied in a wide range of pumping applications where stainless steel is required. The ChemFlo® pumps utilize a semi-open impeller design to allow for the passage of larger solid sizes than similar-sized enclosed impellers. Several seal options are available in addition to the standard type 2100 carbon / ceramic / Viton mechanical seal. Multiple impeller trims allow the ChemFlo ® to meet most duty points.

Oberdorfer’s Gear Pump

Gardner Denver Pumps

Oberdorfer may not have invented the gear pumps, but you could say they’ve perfected it. Founded on their line of bronze gear pumps, Oberdorfer continues to lead the industry in quality and innovation. The helical gears, which are cut on an angle to the face of the gear, allow for more material contact resulting in a better hydraulic range and quieter operation. While some manufacturers offer a few variations, Oberdorfer has a full selection of styles and models, which include:

  • External Gear Pumps
  • Pedestal Mount Gear Pumps
  • Clutch Driven Gear Pumps
  • Motor Mount Gear Pumps

Pump models feature a wide variety of construction materials to best suit your application. Choose from: bronze, lead-free alloy, stainless steel, cast iron, Hastelloy c, or non-metallic models of gear pumps.

Oberdorfer’s Centrifugal Pumps

Gardner Denver Pumps

Oberdorfer centrifugal pumps are of the single-stage and end suction. Models use open vane style and enclosed style impellers. Centrifugal pumps convert driver energy to kinetic energy in a liquid by accelerating it to the outer rim of a revolving impeller. Since the amount of energy given to the liquid corresponds to the velocity at the impeller vane tip, the faster the impeller revolves (or, the larger the impeller is), the higher the liquid’s momentum at the vane, the greater the energy transferred to the liquid. Compared to positive displacement devices, Centrifugal pumps are quieter and require no relief valve to protect the pumps from pressure build-up.

These pumps contain few moving parts resulting in less wear and less maintenance. Our centrifugal family models are made of bronze, which is ideal for marine applications and for handling harsh solvents. Our centrifugal pumps provide up to 20 feet of suction lift and can handle the most difficult solvents with the proper fluoroelastomer or Polytetrafluoroethylene (PTFE) seal. Several of our centrifugal models are self-priming.

Oberdorfer’s Flexible Impeller Pumps

Gardner Denver Pumps

Impeller pumps are used mainly in grey water and black water transfer, engine cooling, baitwell, air conditioning, and other essential functions on boats, ships, and other marine applications. Pump styles include both pedestal style or flange mounted. On initial startup, the impeller pumps must be primed to prevent dry-running of the impeller. Suction lifts of 15 feet are possible when the pump is fully primed. A foot valve with a built-in strainer at the beginning of the suction line is recommended. Suction lines should be short as possible, while horizontal runs if needed, should be pitched upwards towards the pump. All pedestal and flange-mounted impeller pumps are made of high-quality bronze and offer maximum corrosion resistance. All shafts are constructed of grade 303 stainless steel. Choose from low flow, medium flow, or high flow flexible impeller pumps to fit your application.
