7.5KW Submersible Sewage Pump, submersible water pump, fish pond water drain pump


About WQ pump


WQ series submersible sewage pump is mainly used for municipal works, industrial buildings, hotels, hospitals, people's air defense, mines etc. Trades to drain off the sewage, waste water, rainwater and living water in cities containing solid grains and various long fabrics.


As its good performance and high quality, WQ series diving sewage pump is widely used.

Structure and materials of pump


Bearing:  ball bearings with a reasonable configuration, extending the duration of the pump.


Cooling: cooling system for 11KW motor or larger motor can ensure the pump normally work whether the motor is on or under the liquid surface. A part of the liquid is extracted to bring out the beat produced by the motor from the pump circulation to the cooling barrel and to the pump casing and, when external cooling is required, the cooling sleeve may be separated from the pump casing and individually connected to the cooling system.


Motor: Of F class insulation, max. working temperatures 155 ℃, and of a protective grade IPX8 with the effective seal.


Mechanical seal: Use Bogman mechanic al seal of Germany, two ways of the seal are in series with each other and individually work to separate the motor from the pump seal to provide the motor with a dual protection. The sealing material on the pump side is tungsten carbide, while on the motor side, graphite/silicon carbide.


Oil chamber: Oil can lubricate and cool the mechanical seal and realize the attached function of safety by preventing liquid from penetrating into the motor. The air of a certain amount left inside of the chamber can lower the pressure accumulatively raised.


Impeller: With the optimized design, the impeller wil not be blocked up when to transport liquid with its optimum flow and rate and the maximum efficiency. There are suitable impellers at choice for every point of working condition.


Pump case: use the know-how of CAD/CAM for achieving higher efficiency.


Shaft: The pump is coaxial with the motor and the sealing device on the end of the shaft avoids contact with the medium so as to protect it from corrosion. The as short as possible designed stretched rotating ensures no deflection and low vibration, extend the duration of both mechanical seal and bearing and lower the noise at running.
