C.R.I. Regenerative Monoset Pumpsets volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristic. Sealing is by means of a bellows mechanical seal made of carbon & ceramic is fitted over the shaft, which is ground to close tolerance. Brass insert provided inside the pumpset reduces wear & tear, ensure durability and prevents the pumpsets from seizing, if it is kept idle for long Period. These pumpsets are with inbuilt check valve on the sunction side and there is no need for foot valve. Pumpsets are powered by a totally enclosed fan cooled, AC induction two pole and four pole motors suitable for continuous duty. Motor stator is made of low watt loss steel lamination.

Dynamically balanced rotor ensures vibrations and noise free operations. Constructions of motor frame and usage of quality materials result&n...

Sealing is by means of a bellows mechanical seal made of carbon and ceramic fitted over the shaft, which is ground to close tolerance. These pumpsets are power-driven by a totally enclosed fan cooled AC induction two pole motor, suitable for continuous duty. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration free and noise free operations and increase the life of the bearings and seal. The windlings are of high – grade enameled copper wire and are varnish impregnated. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life c...
