OS large flow volute single stage double suction split-casing centrifugal water pump
OS large flow volute single stage double suction split-casing centrifugal water pump
Perfect appearance:
Introduction:
1. OS high flow rate industrial water pump single-stage multi-stage double suction centrifugal pump large split case volute pump is a large flow rate centrifugal pump.
2. Compact structure nice appearance, good stability and easy installation.
3. Stable running the optimally designed double-suction impeller makes the axial force reduced to the minimum and has a blade-style of very excellent hydraulic performance, both internal surface of the pump casing and the impeller a surface, being precisely cast, are extremely smooth and have a notable performance vapour corrosion resisting and a high efficiency.
4. The pump case is double volute structured, which greatly reduces radial force, lightens bearing's load and prolongs bearing's service life.
5. Bearing to use high quality brandname bearings to guarantee a stable running, low noise and long duration.
6. Shaft seal use BURGMAN mechanical seal or packing seal.
Main application:
Water works, irrigation, draining pump station, electric power station, air-conditioning circulation water, industrial water supply system, fire-fighting, shipbuilding industry and general use in oil refining industry.
