ZW inline drain pump for waste water electric self-priming sewage
pump
Electric self-priming sewage pump belongs to self-priming
centrifugal oil pump, and the feature is simple construction, easy
operation, convenient repairing, high displacement, high
efficiency, wide application scope etc.
The pump is composed of suction room, store liquid room, vortex
room, liquid returning hole, gas and liquid dividing room etc. The
pumps adopt the single-row radial ball bearings, and have the
cooling room in the bottom of the bearing stand, and a seal ring is
used between the high press and low press area in the pump. They
adopt mechanical seals on shaft end.
