Our Products
Our Complete range of products are Borewell Submersible Agriculture Pumps and Borewell Submersible Pumps.
C.R.I. 250 mm (10") Borewell Submersible pumpset is made with different materials of construction together with extremely tough hardwearing bushes which make this pumpset highly durable. This pumpset is supplied with stainless steel & LTB-2 impellers to give better performance and longer life. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. This pumpset is powered by a water filled, rewindable submersible motor, which is suitable for continuous duty. The stator is wound with special waterproof 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 thrust bearings (SS AISI 420 with Graphite 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.

C.R.I. 80 mm (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 check 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.
