Centrifugal Jet Self Priming Pumps - CJS Series

C.R.I. Centrifugal Jet self priming pumpsets pump casing and ejector unit 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 pumpsets using quality raw materials, dynamically balanced impellers and rotors to ensure long life. These pumpsets are powered by a totally enclosed fan cooled. AC induction motor, suitable for continuous duty. Motor stator is made of low watt loss steel laminations assembled under pressure and rigidly locked in the frame.
