150 mm (6") Borewell Submersible Pumpsets

C.R.I. 150 mm (6”) Borewell Submersible pumpsets are built with different materials of construction together with extremely hardwearing bushes which makes this pumpsets highly durable. Radial flow submersible pumpsets are supplied with stainless steel impellers and stage casings and mixed flow pumpsets are supplied with LTB-2 and casted steel impellers to give better performance and longer life. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. These pumpsets are powered by a water filled, rewindable submersible motor suitable for continuous duty.
