Product Description

CAT 5CP2120W Plunger Pump

This CAT Pump 5CP2120W pressure washing pump features concentric, high-density, polished, solid ceramic plungers for longevity and extended seal life. The manifold is made of a high tensile strength W770 alloy for continuous duty. The 100% wet seal design lets pumped liquids cool and lubricate on both sides. In addition, stainless steel valves, seats, and springs provide corrosion-resistance for a long life. 

CAT Pumps have exclusive low-pressure and hi-pressure seals for unbeatable performance. Plus, the press-in style seal case offers excellent alignment, support, and tool-free servicing.

CAT Pumps pressure washing pumps are known as the pumps with nine lives because of their dependability. This triplex plunger pump is designed to deliver smooth, low pulsation flows at a variety of pressures and flow rates.
