CRI Stainless Steel Series

B & L Pumps stock Submersible pumps that are the product of expertise gained from over four decades of experience, endurance and workmanship. These products are engineered to perfection with utmost care and stringent quality control at all stages to ensure a trouble free service.

Description: C.R.I. 4″, 6″ & 8″ Stainless steel series submersible pumps are made of corrosion resistance stainless steel with built in check valve. All vital components of these pumps are made of high quality 304 / 316 grade stainless steel and the shaft is of S.S 304 / 329 / 431. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency.

These pumps are of multistage centrifugal type, which can be firmly coupled to a submersible electric motor, which operates submerged beneath the surface of water.
