C.R.I. horizontal multi stage centrifugal pumps 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 pump is a non-self priming horizontal centrifugal pump with mechanical shaft seal and sealing is by means of bellows mechanical seal.
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 laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration free operations. Shaft is made of quality stainless steel, precision ground of ample size for transmitting the rated horsepower. All single-phase pumps are incorporated with thermal over load protector. These pumps require an adequate starter/motor protection control panel.
