Genuine OEM Cat Pumps

This is a triplex [three plunger rods] positive displacement, reciprocating, plunger pump, constructed of a brass manifold, 304SS valve assemblies, solid ceramic plungers and standard NBR [Buna-N] seals and o-rings. This is a hollow-shafted pump designed to bolt directly to a gas engine with a 1" shaft.

Features:

Triplex design provides smoother liquid flow.
Unique spring loaded inlet valves and the flow through ceramic plungers allow excellent suction capabilities.
Compact, hollow shafted pump for direct mounting to either gas or electric motor, eliminates the need for pulleys, belts, gearboxes.
Regulating Unloader mounts directly on each pump to assure system pressure control and pump protection.
Convenient multiple porting provides installation flexibility.
