WQ and QW series non-clog submerged motor pumps are strictly designed, manufactured and tested according to relative national standards. They are applicable for commercial wastewater, daily wastewater, drainage system of city wastewater. Flow extent ranges from 5~6000m³/h, head extent from 5~60m, power extent from 0.55~315KW and caliber extent from Φ25~Φ600mm

 

PRODUCT FEATURES

1.Its unique single-vane or double-vane impeller structure contributes much to pollutant handling capacity. It enables to effectively deliver fibers 5 times of pump caliber and solid granules of diameter at 50% of pump caliber;

2.Its mechanical seal uses late-model corrosion-resistant carbon tungsten hard alloy. In addition, seal is upgraded to double-end sealing for long-term operation in oil chamber and safe service of continuously more than 8,000hours.

3.Compact overall structure, small volume, low noise, distinctive energy saving, easy maintenance, no need for a pump room, service while being put into water, and low construction cost.

4.The sealed oil chamber of this pump is provided with high­ precision anti-interference water leakage detection sensor. That is to say, athermosensitive element is pre-embedded inside stator windings to effect full protection to pump motor.

5.A full automatic safety protection control cabinet is available if required to fully prevent pump from water leakage, electric leakage, over load and excessive temperature and so on. In this way, the safety and reliability is greatly enhanced.

6.The float ball switch may automatically control the start and stop of pump responding to the changes of required liquid level. It is fairly easy to use with no need for a special person to care about it.

7.Double-guide automatic coupling installation system is available if required, making installation and maintenance much convenient, so that there is no need for a person to go into sewage pit.

8.It can be used within full head extent and prevent motor from overload.

9.Two different installation types, fixed automatic coupling installation system and portable free installation system.
