Griswold® 811 CC Series Pumps

Griswold® 811 CC (Close-Coupled) Series centrifugal pumps match the features, flexibility, and performance of standard 811 pumps while incorporating a compact, space-saving design that offers significant benefits.

The 811 CC Series pump utilizes a dimensional liquid end that allows easy adaptation to existing ANSI installations. This means that the pump can “drop” right in line using existing piping, providing an easy and economical replacement for most ANSI installations.
