Our Products
We offer the best product range of CRI Borewell Submersible Pump (100 MM), CRI Borewell Submersible Pump (150 MM), CRI Borewell Submersible Pump (200 MM), CRI Borewell Submersible Pump (250 MM) and CRI Borewell Submersible Pump (175 MM).
C.R.I. 100mm (3") Submersible pumpsets are built with thermoplastic impellers, diffusers and inbuilt check valve. All vital components of these pumpsets are made of corrosion resistant thermoplastic and the shaft is of SS 304/410. Pumpsets are multistage centrifugal type. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency.
The pumpset is firmly coupled to a submersible electric motor which operates submerged beneath the surface of water. Built-in chek valve prevents back flow and reduces the risk of water hammering. All mounting dimension of 100 mm (4") pumpsets and motors upto 2 HP are in accordance with Nema standard.

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. The stator is wound with special water proof synthetic film insulated copper winding wires and made up of low watt loss silicon steel laminations assembled under pressure and rigidly locked in stainless steel stator shell. Specially designed high performance thrust bearings (SS with Carbon) are used to withstand axial and down thrust loads with minimum wear and tear. Dynamically balanced rotor gives vibration free and noise free operation, thereby increases efficiency and life cycle of the motor.
