Vertical Multistage Pumps MV – Series

C.R.I.’s vertical multistage centrifugal pumps (MV Series) are non self priming axial suction and delivery type available with DIN standard for connection. All components like impeller, diffuser & shaft of these pumps are made of corrosion resistant AISI Stainless Steel and designed to deliver the best possible hydraulic efficiency. ‘O’ ring and gasket prevents leakage at the intermediate casing during high pressure.

These 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 lamination assembled under pressure and rigidly locked in the frame.Dynamically balanced rotor ensures vibration and noise free operation. Shaft of Ample size made of quality steel and precisely ground is used for transmitting rated Horse Power. Thermal over load protector is incorporated in all single phase motors.
