Deepwell Submersible Pumps – Stainless Steel Series

C.R.I. 4″,6″,8″ & 10″ Stainless steel series submersible pumps are made of corrosion resistance stainless steel with built in check valve.All vital components are made of high quality 304/316 grade stainless steel and the shaft is SS 304/329/431. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency. These pumps are of mulistage centrifugal type, which can be 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 hammer. All mounting dimensions of pumps are in accordance with NEMA standards. These Pumps can be offered with C.R.I. water filled rewindable/ Oil filled / Resin filled encapsulated submersible motors or any other NEMA standard motors
