Summary
ZW Non Clogging Self priming sewage centrifugal pump is based on the diffuser principle, this pump is a combination of self priming and non clogging. It adopts wide flow channel of the impeller to transfer sewage with big solids, long fiber impurity, sediment impurity.

Construction

Advantage
1. Back-pull-out construction: Convenient formaintenance and troubleshooting.
2. Daily maintenance can be performed rapidly bycommon tools,saving time and labor.
3. Strong solids passing capacity:wide flow path impeller structure and non-clogging design.
4. with only the suction line down in the liquid (thepump shall be filled with water for first start).
5.the series of ZW series self-priming pumps do not need to install a bottom valve, but only need to ensure that there is a quantitative amount of liquid in the pump body.
