Cast Iron Sewage Water Pump Manufacturer – WZ Self-Priming Dredge Pump(the Third Generation) – State Machinery Equipment Manufacturing

product description

ZW self-priming blockage sewage pump is a self-priming and sewage 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. kind. It can not only need to install a bottom valve like a general clean water self-priming pump, but also does not need to irrigate and divert water, but also can suck the dirt, sediment, sediment, which contains large particles with a diameter of 60% of the outlet diameter and a fiber length of 1.5 times the diameter of the impeller. Waste ore impurities, excrement treatment and all engineering sewage and colloidal liquid, completely reduce the labor intensity of human labor, and easy to install and use, less maintenance, has a broad application market and development prospects

Scope of application

Suitable for chemical, petroleum, pharmaceutical, mining, paper, fiber, pulp, textile, food, power plants and municipal sewage projects, public facilities sewage, river pond aquaculture and other industries.

Application Scope

1.Ambient temperature ≤50℃; medium temperature≤80℃.
2. Medium PH: 6-9 for cast iron pump and 2-13 for stainless steel pump.
3. Medium unit density not exceeding 1,250kg/m³.
4. Self-priming height not exceeding the set value, and suction pipe length ≤10m.
5. The diameter of the suspended particles is 60% of the diameter of the pump, and the fiber length is 5 times the diameter of the pump.

product advantages

1. Strong sewage discharge capacity: The special impeller anti-blocking design ensures that the pump is free from blockage.
2. Energy saving: The hydraulic model is adopted, and the efficiency is 3-5% higher than that of the general self-priming pump.
3. Good self-priming performance: The self-priming height is 1 meter higher than the general self-priming pump, and the self-priming time is shorter.
