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.
