Centrifugal Jet Self Priming Pump Set - CJS Series

We offer Centrifugal Jet Self Priming Pump Set - CJS Series that features pump casing and ejector unit, which are designed carefully to give the best possible hydraulic efficiency and suction lift characteristics. Sealing is by means of a bellow mechanical seal made of carbon & ceramic is fitted over the shaft, which is ground to close tolerance. Most modern and highly sophisticated machinery and technology are employed in the manufacturing of these pump sets using quality raw materials, dynamically balanced impellers and rotors to ensure long life. These pump sets are powered by a totally enclosed fan cooled and AC induction motor is suitable for continuous duty. Motor stator is made of low watt loss steel laminations assembled under pressure and rigidly locked in the frame.

Dynamically balanced rotor of our Centrifugal Jet Self Priming Pump Set - CJS Series ensures vibrations and noise free operations as well as increases the life of bearing and seal. The varnish impregnated windings made of enameled copper wire offer excellent resistance. Shaft is made of quality steel, precision ground of sample size for transmitting the rated Horse Power. Construction of motor frame and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the motor. T.O.P (motor protector) is incorporated in all single-phase motors. All single-phase pump sets require an adequate motor protection control panel.
