5 Frame Plunger Pump

Industrial Duty, Long Lasting, Dependable Pumps

Model: 311C

This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with a 316 stainless steel manifold, 316 stainless steel valve assemblies, solid ceramic plungers and standard NBR (Buna-N) seals and O-rings.

The "C" indicates the pump is built with a unique flushed inlet manifold that permits an external liquid to provide added cooling for high-temperature fluids and lubrication for low-lubricity liquids like DI (deionized) water. When used with the 990663 Flushing Assembly, the package offers a self-contained fluid source for pumping through the flushed manifold.
