Pressure Boosting Pumps

Multistage Horizontal Booster Pumps MHS/MHL Series

C.R.I. Horizontal Multistage Centrifugal pumpsets are axial suction and vertical radial delivery with threaded ports. The impellers, diffusers and shaft of these pumps are made of stainless steel and designed to deliver the best possible hydraulic efficiency. This pumpsets is a non-self priming horizontal centrifugal pumpsets with mechanical shaft seal and sealing is by means of a bellow mechanical seal.
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 silicon steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration free and noise free operations. Shaft is made of quality stainless steel, precision ground of ample size for transmitting the rated horsepower. All single-phase pumpsets are incorporated with TOP. These pumpsets require a adequate starter/motor protection control panel.
