C.R.I. 4" Stainless steel series submersible pumps are made of corrosion resistance stainless steel with built in stainless steel check valve for years of trouble free service. All vital components are made of anti-corrosive high quality 304/316 grade stainless steel and the shaft is SS 304/329 and well designed for the best possible hydraulic efficiency. Pumps are multistage centrifugal type. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency. The pump is firmly coupled to a submersible electric motor which operates submerged beneath the surface of water.  Built in check valve prevents back flow and reduces the risk of water hammering. Pumps can be offered with either C.R.I. 'W' Series, water filled rewindable submersible motors / C.R.I. 'R' Series, encapsulated semi wet type submersible motors or any other NEMA Standard motors.
