C.R.I. Regenerative Monoset pumpsets volute chamber and impellers are designed to give the best possible hydraulic efficiency and sunction lift characteristics. 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 cycle of the motor. A thermal cutout relay (motor protector) is incorporated in all single-phase motors. All single-phase pumpsets require a adequate starter / motor protection control panel. Non-self priming model is with end suction and radial delivery.
