Centrifugal Monoblock Pumps - CH, CS, BP SERIES

C.R.I. Centrifugal monoblock pump’s volute chamber and impellers are designed to give the best possible hydraulic efficiency and good suction lift characteristics. Most modern and highly sophisticated machinery and technology are employed in the manufacture of these pumps using quality raw materials. Dynamically balanced impellers and rotors are ensuring the long life of the pump. These pumps are powered by a totally enclosed fan cooled A.C. Induction two pole motor or four pole motor is suitable for continuous duty . Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame.
