Product overview
ZW type self-priming non clogging sewage pump is a new type of pump which integrates self-priming and sewage discharge according to the structure and performance of ZX self-priming centrifugal pump and QW submersible sewage pump, and drawing on the advantages of similar products abroad. It not only does not need to install the bottom valve, does not need to inject water, but also can suck the dirt, sediment, waste mineral impurities, fecal treatment and all engineering sewage and colloidal liquid with the diameter of 60% of the outlet diameter and the fiber length of 1.5 times of the impeller diameter, which completely reduces the labor intensity of manpower, and is easy to install and use, with little maintenance and performance It has reached the international advanced level and has broad application market and development prospect
The company has strong technical force, rich production experience and perfect detection means, so as to ensure the stability and reliability of product quality.
Product advantages
1. Strong blowdown capacity: special impeller anti blocking design ensures high efficiency and no blockage.
2. High efficiency and energy saving: adopting better hydraulic model, the efficiency is 3-5% higher than that of general self-priming pump.
3. Good self-priming performance: the self-priming height is 1 m higher than the general self-priming pump, and the self-priming time is shorter.
