1、 Product Overview

The pump integrates self-priming and non clogging sewage discharge. It can not only eliminate the need for bottom valve and irrigation water like ordinary clean water self-priming pumps, but also pump dirt, sediment, waste mineral impurities, fecal treatment and all engineering sewage containing large particle solids and long fibers, completely reducing the labor intensity of workers, and it is easy to use, move, install, rarely maintain, and has stable performance.

Scope of use

1. Ambient temperature ≤ 45 ℃, medium temperature ≤ 60 ℃.

2. Medium PH value is 6~9 for cast iron pump and 1~14 for stainless steel pump.

3. The larger diameter of passing particles is 60% of the pump diameter, and the fiber length is 5 times of the diameter.

4. The total weight of impurities in the medium shall not exceed 15% of the total weight of the medium, and the specific gravity of the medium shall not exceed 1240kg/m3.

5、 Structural characteristics

ZW type self-priming sewage pump is developed by our designers according to the structure and performance of ZX type self-priming centrifugal pump and QW type sewage pump, drawing on the advantages of similar products at home and abroad, and absorbing the use requirements and suggestions of users in many aspects. It not only eliminates the need for bottom valve, irrigation and water diversion, but also can pump dirt containing large particle solids, long fibers, settling objects The treatment of waste mineral impurities, feces and all engineering sewage and colloidal liquids can completely reduce the labor intensity of workers, and it is convenient to use, move and install, with little maintenance and stable performance.
