QW Submersible Sewage Motor Pumps

Applications and Features Features: QW series submersible sewage pumps are designed on the basis of absorbing advanced foreign and domestic technology. This kind of pump is composed of two parts: motor and pump. Motor and pump is separated oil chamber and mechanical seal. Motor and pump are with same shaft. The pumps are of lower height, compact and equipped with several kinds of protection devices marking the pumps operating more safety and reliably. High quality lubricating bearings guarantee the pumps to run long time without maintenance . Elaborative protection devices to protect the pump from seal leakage , motor of overload and bearing of overload to assure the safety and reliability of pumps. High efficiency and big flow passage of impellers and also its no-clog structure ensure the pumps pass big solid particles and fibers and greatly decrease the occurs of troubles. Carefully selected high quality mechanical seal with material SiC/SiC(orTC/TC)can guarantee the mechanical seal could be used reliably in oil chamber for long time. Application: Rain water and waste water in general. City construction engineering and construction field. Sewage water drainage of environmental protection engineering. Waste water drainage of residential area. Sewage water and sediment of water purification system. Heavy pastes and liquid in food and pharmaceutical processing industry. Waste water drainage for hospitals, hotels and restaurants etc. Waste water for leather industry and slaughterhouse. Beer and sugar industry. Textile industry. Drainage system for city sewage treatment industrial. Drainage system for underground structure. Heavy polluted wastewater drainage for factories or commercials.
