5 Frame Plunger Pump
Industrial Duty, Long Lasting, Dependable Pumps
Model: 340S
This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with a chrome-plated brass manifold with 304 stainless steel sleeve inserts, 304 stainless steel valve assemblies, solid ceramic plungers and standard NBR (Buna-N) seals and O-rings.
Cat Pumps "S" Series manifolds include precision press-fit 304 stainless steel sleeve inserts in the sealing areas and valve chambers of the manifold to help eliminate manifold washout and extend pump life.
The 1725 RPM permits multiple drive options, including direct drive with a bell housing and flexible coupling, clutch or belt drive.
