ZW type stainless steel self priming sewage pump] Products: 

 ZW type non-clogging self priming sewage pump, also known as solid-liquid pump or trash pump. Is a set of self-priming pump and clogging sewage pump, using the mixed-type axial reflux, unique hydraulic design, the impeller is shrinking in a separate impeller room, connecting the impeller chamber is a pressurized water chamber, when the impeller rotates, the pump within the liquid to produce a strong axial vortex role of imports caused by the vacuum exports head. Therefore impurities can be discharged from a pressurized water chamber, so the flow is completely smooth, the effect of its sewage is unparalleled self-priming sewage pump. General self-suction clean water centrifugal pump did not need to install the end of the valve and the irrigation water containing large particles of strengthening the economy and long-fiber liquid impurities, but also suction through the pump body, impeller, unique design, you can like. 

 [ZW-type stainless steel self priming sewage pump] Model significance:

 ZW type non-clogging self priming sewage pump and the like domestic product, compared to a simple structure, self-priming performance, sewage capacity, energy efficient, and easy maintenance. 
 ZW type non-clogging self priming sewage pump sewage pump series is a national initiative. The technical performance indicators lead at home to reach the international advanced level, has a broad application market and prospects for development. 

 [ZW Non-clogging self priming sewage pump] Usage: 

 ZW type non-clogging self priming sewage pump valve end of the self-priming pump so no need to install can be as general, but also suction contain large particles of solid, long fiber, sediment, mine waste impurities, excreta disposal, and all works of sewage. Can be widely used in municipal sewage works, light industry, papermaking, textile, food, chemical, electrical, petroleum, mines and rivers and ponds and breeding industries. It is the best trash pump in the domestic pumping of solid particles, fibers, pulp and mixed suspensions and other media.

 ZW clogging self priming sewage pump installation is good or bad, have a greater impact on the operation and life of the pump, it must be carefully carried out. (Standard pump piping installation see diagram) 
 ZW clogging self priming sewage pump suction installation height so as not to over 5 meters, should pay particular attention to the tightness of the suction pipe, so as not to leak to affect the pump self-priming capacity and normal operation. 
 2, ZW-clogging self-priming sewage pump at the exit should be installed for some vertical tube (typically 0.4 to 1 m) and a pressure gauge, and then install the outlet flow control valves and other piping. 
 3, to the rational allocation of pump inlet, the length and diameter of the outlet pipe, to reduce unnecessary frictional head loss. (Refer to the pipe friction loss table estimates) 
 4, long-distance transmission should be selected larger diameter. Pump piping should have its own stand, the pump itself to withstand the load of the piping is not allowed. 
 5, the discharge pipe loaded check valve should be installed in the outlet flow control valve outside.
