4 GPM - Washout Resistant Plunger Pump

The CAT Pumps 310S features a special "S" Series manifold that includes precision press-fit 304 stainless steel sleeve inserts in the sealing areas and valve chambers to prevent manifold washout extending the longevity of the manifold. Features a chrome plated brass manifold, 304 stainless steel valve assemblies, solid ceramic plungers with NBR (Buna-N) seals and O-rings. High pressure seals are lubricated and cooled by the liquid being pumped which extends the life of these components.
