WQ submersible sewage pumps are developed on the basis of adsorbing advanced technology from famous pump manufacturing company in German, with advantages of high technological starting point, obvious energy saving capability, strong matching capability, wide applicability and so on, are listed as key introduced and digested products by former State Committee of Machinery Industry, and have passed the export quality certification and CE certification. After put into the market, the products win favorable comments due to their unique functions and reliable quality, not only are far resold to international market in batch, but also are selected by many national key construction projects to substitute for imported products. This type of products had the honor to be listed as developing item of “Torch Program” by State Science and Technology Commission in 1995, as recommended products by Ministry of Construction, and as promotion products by State Science and Technology Commission in 1997.

Range of use and service condition

Ph: 5~9. Water temperature≤40℃.

Water Special working media such as: high temperature, slightly corrosive media, sea water and others can be customized.

Structure description diagram

This WQ submersible sewage pump adopts advanced technology from foreign countries, has reasonable structure and superior performance. Operating mode of squirrel cage motor is S1, stator insulation class is F (155℃). With condensation - resistant device, and there is overload protection element for each phase.

The special "LSK-1 series" water pump and water treatment equipment special control cabinet are adopted to ensure durable equipment and stable and reliable operation. (refer to next pages for details)

1.WQ submersible sewage pumps adopt large-channel anti-block hydraulic power parts, which allow solid particles of dia. 125MM to pass smoothly.

2.The electrical motor adopts water jacket type circulated water cooling system to make sure that the electric pump can work reliably under dry condition.

3.Unique condensation-proof device of motor, removes dampness from the motor automatically to keep its insulation at 300M above at high temperature, make sure that it can work normally and reliably.

4.Automatic coupling system, simple installation, need not pump house, which cut down the construction cost and running cost sharply.

5.The automatic protection system has multifunctional running display, which can make centralized control to every running state and protect it effectively.

6.WQ submersible sewage pumps can be applied to municipal engineering, factory, commerce, hospital, hotel, residential area and so on, used to drain sewage, waste water or rainwater that contain solid particles or long fibers, also can be used to supply water and irrigate agricultural land.

Impeller design

Wangyang bravely Innovates submersible sewage pump on the aspect of general structure and hydraulic model design, and employs CFD flow field analysis technology and finite element analysis. The impeller vibrates little during performing balance inspection, so that the pump can run stably. The impeller is processed separately to reach the specified working Points, so as to carry the liquid with the best flowing way and speed and max efficiency.

Large-channel impeller

Be used for carrying the wastewater with large solid particle. Large-channel impeller runs in the volute casing. The shape and size of channel doesn't bring the jam, therefore, it is the ideal that the impeller is acted as pump to carry the waste water with large solid particle.

Peripheral impeller

Be suitable for wastewater with solid particle. The water process of peripheral impeller that is the impeller triggers the vortex flow in rapid rotating and makes hydraulic pressure rise. Most of the solid particles in the liquid will not come into contact with the impeller, greatly reducing wear and improving the service life of the pump.

Multi-blade impeller

The impeller is designed into multi-blade type, can carry water effectively without blocking.

Mornitoring and control system design

Fixed wet type mounting

Adopt Wangyang dual rail automatic coupling device, the pump can slide to the mounting position on base along this dual rail and seal the outlet connection point automatically.

Fixed dry type mounting

Install the pump base on a support bracket in fixed dry type, which is suitable for the pumping station that has individual collecting pool or water tank, saves space and mounting cost, really is the ideal selection for reconstructing old pumping stations that have major axis pumps.
