ZW Non-Clogging Self-Priming Sewage Pump
PRODUCT DESCRIPTION
ZW self-priming non-clogging sewage pump is a newly developed product with novel structure.
on the basis of repeated research of similar technologies at home and abroad . The pump integrates the advantage of self-priming and non-clogging,the unique design of pump body with impeller channel is used to combine self-priming and non-clogging functions .
Compared with domestic products,the pump has the characteristics of good self-priming performance,strong blowdown capacity,simple structure,beautiful appearance and so on.
With wear-resistant mechanical seal patent structure,can run for long time without load
No need to install the bottom valve,no need to inject water,and can be pumped containing large particles of solid blocks,long fibers of dirt,sediment waste mine impurities,fecal treatment and all engineering waste

Liquid pH value: 5-9
Liquid density: ≤1.2 x103kg/m3
Self-priming height: Should not exceed the self-priming height specified by the pump,the total length of the suction pipeline should not exceed 10 meters.
Passing capacity: The suspended particle diameter can not exceed 60% of the pump diameter, and fiber can not exceed 5 times bigger than the pump diameter.
