ZW  series sewage pump overview:

It is developed based on the structures and characteristics of ZX centrifugal pump and
QW drainagepump, referring to the advantages of similar productions at home and abroad,
soliciting the demands and opinions of various customers. It is integrated with self-suction
and drainage, which doesn't need to fix a foot valve or fill inducting water as common clean
water self-suction pump and can pump sewage, sediment, waste mine impurity, dejecta
containing great suspended solid sewage with a diameter 60% as the outlet diameter and
fibrous things whose lengths are 1.5 times as the impeller and all engineering sewage and
colloid liquid, completely reducing workers' labor intensity. It is easy to use, move and fix,
seldom needs maintenance and performs steadily.
