Summary

      WL series vertical sewage pump  is a new-generati on product successfully developed by this Co. by  way of introducing the advanced know-how from both at  home and abroad, upon t-
he requirements and conditions of use of  the users and reasonable designing and features high  efficiency , energy saving,  flat  power curve, non-block-up, wrapping-resist ing, good  perform-
ance  etc.
      This series pump uses single(dual) great  flow-path  impeller or the impeller with dual or three baldes and, with the unique impeller`s structure, has a very good  flow-passing performance, and equipped with reasonable spiral housing, is  made to be high effective  and able to transport the  liquids containing  solids, food plastic bags  etc. long fibres or other  suspensions,  with the maximum diameter of the  solid grains  80~250mm and  the fibre length 300~1500mm.
      WL series pump  has a good hydraulic performance and a flat power curve and, by  testing, each of its performance index reaches the related standard. The  product is greatly favoured
and evaluated by  the users since its being  put into the market for its unique efficiency and  reliable performance and quality.

Application

        This product is mainly used to transport  citys  living  sewage,  factory, mine  etc. enterprises sewage, slurry,  night  soil, ash  and  dregs, paper  pulp  etc. also  for  cycle  water  pump, water  supply  and  drain  pumps, exploration, mine  fitted auxiliary  machine, methane-generating  pit  in  countryside, farming   irrigation  etc. purposes.

       1.  The   unique  impeller  design  and   the  great flow-path block-up  vesisting  hydraulic  parts   greatly  enhance  the  ability for  sewage  to  pass  and  effectively  have  fibre  matters  and solid  grains  passing  through.
      2. It  belongs  to   the  integrated  electromechanical  product with  both  pump  and  motor  in  one  shaft  to  directly  drive,resulting  in  compact  structure   and  stable  performance.
      3. Of  a  strong  suitability,  suitable  for   transporting  citys living  sewage, factory, mine  etc.  enterprises` sewage.
      4. Easy  operation, low  cost  for  maintenance; can   be  ov-erally  placed  outdoors  to   work  without  need  of   machine room, saving  great   deal  of  construction  fees.
      5. Mechanical  seal  is  made  of   hard  wearable  corrosion-proof  tungsten  carbide  and   features  durability  and  wearbility  and  can  safely  and  continually  run   over  800h.
      6. The  motor   is  reasonably  fitted  with, high  overall   efficiency, good  hydraulic  performance  and  low  noise  at  running.
