Multistage Centrifugal Pumps
Horizontal Multistage Pumps MHS, MHB & MD – Series
C.R.I.’s Horizontal Multistage Centrifugal Pumps (MH Series) are non-self-priming, axial suction and vertical radial delivery type threaded parts. All vital components like impellers, diffusers & shaft of these pumps are made of corrosion resistance AISI Stainless Steel and designed to deliver the best possible hydraulic efficiency. The pump and motor are connected with a single drive shaft to eliminate any transmission loss. ‘O’ ring and gasket prevents leakage at the intermediate casing during high pressure. Mechanical seal of these pumps are made of ceramic and carbon graphite to ensure reliability and easy replacement. 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 and the varnished impregnated winding made of enamelled copper wire offer excellent resistance. Thermal over load protector is incorporated in all single phase motors.
