Centrifugal Jet Pump Set that we supply is the product engineered to provide perfect solution for various pump set problems. The volute chamber and impellers of Centrifugal Jet Pump Set is designed to provide the best possible hydraulic efficiency and suction lift characteristics. Sealing is by means of a below mechanical seal made of carbon and ceramic is fitted over the shaft, which is ground to close tolerance. Pump sets are available in single stage, double stage and multi stages for various needs. Centrifugal Jet Pump Set is powered by a totally enclosed fan cooled (TEFC) and screen protected drip proof (SPDP), AC induction two pole motor suitable for continuous duty.

Motor stator is made of low watt loss silicon steel laminations. Dynamically balanced rotor ensures vibration and noise free operations and increases the life of the bearings and seal. The windings 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 pump sets require an adequate starter / motor protection control panel. Most of the models of our Centrifugal Jet Pump Set are specially designed to install the pump vertically above the borewell or horizontally at a little offset distance from the well according to customer's convenience.

Our Centrifugal Jet Pump Set is available in twin type and packer type versions. Packer type is suitable for 2" and 3" borewells and twin types is suitable for borewells with a diameter of 3 inch and above in twin type jet pump sets, there are two pipes, viz. Suction pipe and pressure pipe which connects the jet assembly to the pump. Pressurized water flows through the pressure pipe to the nozzle from the pump casing. Water sucked through the foot valve and the water passing through the nozzle mix together and flow through suction pipe into the pump, and for packer type jet pumps, the casing of tube well does the function of pressure pipe, ie., pressurized water through the tube well casing and enters the nozzle. Hence, one pipe eliminated.
