Cat Pump # 2530E Plunger Pump

The Cat Pump 2530E is a Plunger Pump, pump end only, with Brass construction, 1 1/4 inch NPT(F) Inlet port x 3/4 inch NPT(F) Discharge port, and is rated for up to 25 GPM, and 1200 PSI at maximum shaft speed of 1025 RPM. This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with chrome-plated brass manifolds, 304 stainless steel valve assemblies, solid ceramic plungers and standard NBR (Buna-N) seals and O-rings. This pump also features adurable blue two mil epoxy paint treatmenton the crankcase, rear cover and bearing covers and a unique liquid gasket between the crankcase and manifold to seal moisture out. This Plunger pump utilizes spring-loaded closed and hydraulically opened inlet and discharge valves to direct flow through the pump manifold. At the beginning of the stroke, the plunger displaces the liquid in the manifold chamber, forcing the discharge valve open. When the plunger reaches the end of the stroke, the discharge valve closes. As the plunger rod begins its backward stroke, the inlet valve opens to allow more liquid into the manifold chamber, thereby keeping a smooth forward flow of liquid. IMPORTANT : All high-pressure systems require a primary pressure regulating device (e. g. regulator, unloader) and a secondary pressure relief device (e. g. pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to pump or property.
