ZW type explosion-proof self-priming sewage pump

Stainless steel self-priming Sewage Pump overview

ZW self-priming sewage pump, also known as solid-liquid pump or impurity pump. The hydraulic design of this series of pumps is unique. The impeller is shrunk in a separate impeller chamber. The impeller chamber is connected to the pressure chamber. When the impeller rotates, the liquid in the pump produces a strong axial eddy current, which causes the inlet to create a vacuum and the outlet to generate a lift. Therefore, the impurities can be discharged from the pressurized water chamber, so that the flow passage is completely unobstructed, and the sewage discharge effect is unmatched by other self-priming sewage pumps. The ZW self-priming vortex does not block the sewage pump produced by this unit. It can be installed like a general Self-Priming Pump without the installation of a bottom valve, and can also contain large solid blocks, long fibers, sediments, waste minerals, and manure treatment. Everything works sewage. Can be widely used in municipal sewage engineering, light industry, paper, textile, food, chemical, electrical, petroleum, mining and river pond farming industries. It is an ideal impurity pump for pumping solid particles, fibers, slurries and mixed suspensions in China. Performance range flow Q: 8 ~ 800 m3 / h Diameter DN: 25 ~ 300mm Head H: 15 ~ 80m Speed N: 2900 ~ 1450r / min Motor power: 1.5 ~ 55kw.

ZW self-priming non-blocking sewage pump is the self-priming and sewage discharging system developed by our company based on the structure and performance of ZX self-priming centrifugal pump and QW submersible sewage pump, drawing on the advantages of similar foreign products. New pump type. It can be used as a general clean water self-priming pump without the need to install a bottom valve, without water, and can absorb dirt and sediment containing 60% of the diameter of the large solids and 1.5 times the diameter of the impeller. Waste ore impurities, manure treatment and all engineering sewage and colloidal liquids, completely reduce the labor intensity of manpower, and are easy to install and use, rarely repaired, and the performance has reached the international advanced level. It has a broad application market and development prospects. Using computer design and optimization processing, the company has strong technical strength, rich production experience and perfect testing methods to ensure the stability and reliability of product quality.

Stainless steel self-priming sewage pump product advantages

1. Strong sewage discharge capacity: special impeller anti-blocking design ensures that the pump is efficient and non-blocking.

2, high efficiency and energy saving: the use of excellent hydraulic model, the efficiency is 3 to 5% higher than the general self-priming pump.

3, self-priming performance: self-priming height is 1 meter higher than the general self-priming pump, and the self-priming time is shorter.
