Double Suction Horizontal Split Case Centrifugal Pump COS Series for Clean Water
COS Series pumps are double suction horizontal split case centrifugal pump, they are single-stage, double suction, horizontally mounted, applied for general water supply, booster service, municipal waterworks, condenser cooling, water circulation, industrial service, building service, chemical plant, power plants etc.
Features
1. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipe work.
2. The independent bearing housing allows for ease of maintenance without removing the top casing. The double volute design reduces the radial load on the shaft, extending component life, minimizing vibration and providing quiet operation.
3. The pump also offers high efficiency throughout the range. High energy efficiency along with long pump working life and easy maintenance add up to low life-cycle costs.
4. The split case pump is available with a liquid cooled sleeve bearing which promotes longer life and reduces maintenance.
