Cat Pump # 2SFX30ES Plunger Pump

The Cat Pump 2SFX30ES is a Plunger Pump, pump end only, with Brass construction, 3/8 inch NPT(F) Inlet port x 3/8 inch NPT(M) Discharge port, and is rated for up to 3 GPM, and 1500 PSI at maximum shaft speed of 3450 RPM. This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with brass manifolds, 304 stainless steel valve assemblies, solid ceramic plungers and standard NBR (Buna-N) seals and O-rings. 2SF Series pumps are hollow-shafted and designed to bolt directly to either a C-face electric motor or gas engine, depending on the model, providing an easy, compact installation. In this SF series pump, both the inlet and discharge valves are spring-loaded closed and hydraulically opened, similar to plunger pumps, however, they have a flow-through ceramic plunger design. The continuous forward flow characteristic of piston pumps is utilized in conjunction with the packing design of the plunger pumps. These features give SF pumps both strong suction capabilities and higher pressure performances. 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.
