Product Details

Product introduction:

1. ZW horizontal electric centrifugal waste water pump industrial sewage self priming pump is special designed for sewage and waste water transfer and treatment.

2. The sewage pump is with self-priming structure, at the bottom of inlet, there’s a hole for unloading of solids left in pump.

3. It also could be equipped with diesel engine for wild application.

4. The unique structure of open impeller makes sure the free pass of solids in sewage with max size of 60% of outlet DN and fiber 150% of impeller diameter.

5. The self priming pump is widely applicable for the lines of urban diacharge projects, light industry, papermaking, textile, foodstuff, chemicals, electric power, petroleum, mines, aquiculture and so on.
