Sewage centrifugal pump

The sewage centrifugal pump is a new type of pump developed by our company based on the structure and performance of ZX self-priming centrifugal pump and QW submersible sewage pump, and drawing on the advantages of similar foreign products. It integrates self-priming and sewage discharge. It can be used as a general self-priming pump for clean water without the need for a bottom valve or water injection. It can also suck up 60% of the large solid particles with an outlet diameter and 1.5 times the fiber length of the impeller diameter, including dirt, sediment, waste impurities, feces treatment, and all engineering wastewater and gelatinous liquids, completely reducing the labor intensity of human labor. Moreover, it is easy to install and use with minimal maintenance. The performance of self-priming sewage pumps has reached the international advanced level and has broad application markets and development prospects.

2、 Product features of sewage centrifugal pump:

1. ZW self-priming sewage pump has strong sewage discharge capacity: the special impeller anti blocking design ensures high efficiency and no blockage of the pump.

2. The self-priming sewage pump has high efficiency and energy saving: using an excellent hydraulic model, the efficiency is 3-5% higher than that of a general self-priming pump.

3. ZW self-priming sewage pump has good self-priming performance: the self-priming height is 1 meter higher than that of general self-priming pumps, and the self-priming time is shorter.

3、 Application and conditions of sewage centrifugal pump:

Suitable for industries such as chemical, petroleum, pharmaceutical, mining, papermaking, fiber, pulp, textile, food, power plants, municipal sewage engineering, public facility sewage, and river pond aquaculture.

The usage conditions of self-priming sewage pump: 1. Environmental temperature ≤ 45 ℃, medium temperature ≤ 60 ℃. 2. The pH value of the medium is 6-9 for cast iron pumps and 1-14 for stainless steel self-priming pumps. 3. The maximum diameter of the particles is 60% of the diameter of the self-priming pump, and the fiber length is 5 times 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 1240 kilograms per cubic meter
