Centrifugal Monoblock Pumps - Cs Series

C.R.I. Centrifugal Monoblock pump�s volute chamber and impellers are carefully designed to give the best possible hydraulic efficiency and suction lift characteristics. Most modern and highly sophisticated machinery and technology are employed in the manufacture of these pumps using quality raw material, dynamically balanced impellers, seals and ball bearings to ensure long life. C.R.I centrifugal monoblock pumps are powered by a totally enclosed fan cooled, A.C. 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. Dynamically balanced rotor ensure vibration and noise free operations. The varnish impregnated windings made of enameled copper wire offer excellent resistance. Shaft is made of quality steel, precision ground of ample size for transmitting the rated Horse power. 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. These pumps require an adequate motor protection control panel.
