Cat Pump # 2SFP500EL Plunger Pump

The Cat Pump 2SFP500EL is a Plunger Pump, pump end only, with Brass construction, 3/4 inch NPT(M) Inlet port x 3/8 inch NPT(F) Discharge port, and is rated for up to 5 GPM, and 500 PSI at maximum shaft speed of 1750 RPM. This triplex (three piston rods) positive displacement, reciprocating piston pump is constructed with brass manifolds, chrome-plated 304 stainless steel cylinders, 304 stainless steel valve assemblies, FPM piston cup assemblies and standard NBR (Buna-N) seals and O-rings. 2SFP Series pumps are hollow-shafted and designed to bolt directly to a 56C-face electric motor, 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.
