Horizontal Multistage Centrifugal Pumps
OCH Horizontal Multistage Booster Pumps are the products of the expertise gained from over four decades of experience, endurance and workmanship. OSWAL products are engineered to perfection with utmost care and stringent quality control at all stages to ensure a trouble free service.
OSWAL horizontal multistage 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 a bellows mechanical seal.
These pumps are powered by at any 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 and noise free operations. Shaft is made of quality stainless steel. All single-phase pumps are incorporated
with thermal over load protector. These pumps require an adequate starter/motor protector control panel.
