submersible sewage pump / dirty water pump
1,ProductionOverview:                                                                                                                                       
   

    WQ and QW series non-clog submerged motor pumps are strictly designed, manufactured and tested according to relative national standards. This pump has been improved for many times  and developed successfully  through the joint efforts of our company's R&D personnel based on the extensive opinions from domestic experts on water pump. All of its performance indexes have reached the advanced level of foreign like products through the test.

      
 2,Main Features:                                                                                                                                                

   

   a) 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;                                                                                                                                                                                                                            b) Its mechanical seal uses late-model corrosion-resistant carbon tungsten hard alloy. In addition, seal is upgraded to double-end sealing forlong-term operation in oil chamber and safe service ofcontinuouslymore than 8,000hours.                                                                                                                                                                                                                    c) Compact overall structure, small volume, low noise, distinctive energysaving, easy maintenance, no need for a pump room, service whilebeing put into water, and low construction cost.                                                                                                                                                                                                                                d) The sealed oil chamber ofthis pump is provided with high-precision anti-interference water leakage detection sensor. That is to say,athermosensitive element is pre-embedded inside stator windings toeffect full protection to pump motor.                                                                                                                                                                                                                              e) 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.                                                                                                                                                                                                                          f)The float ball switch may automatically control the start and stop of pump responding to the changes ofrequired liquid level. It is fairly easy to use with no need for a special person to care about it.
  g) 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.
  h)It can be used within full head extent and prevent motor from overload.
  i) Two different installation types, fixed automatic coupling installation system and portable free installation system

       
3,Main Usages:                                                                                                                                                                                       

   

     WQ series submersible sewage pumps are mainly used for municipal project, buildings, industrial blow-off, hotels, hospitals, civil air defense, mine, etc. And it can also transport the sewage, waste water, rainwater and living water which containing solid grains and various of long fibre.
