Horizontal sewage self-priming pump
ZW self-priming centrifugal pump adopts axial backflow outward mixing. It does not need to install the bottom valve and irrigation water and the pump can suck the liquids.
ZW self-priming pump is equipped with the impeller of wide flow passage and volute house. All engineering sewage and slurry containing large particles solid and long fiber garbage, such as sewage, sediment, waste ore impurities, etc., can be pumped out.
It has the characteristics of simple structure, good self-priming performance, strong discharge capacity of sewage, high efficiency and energy saving, convenient operation and maintenance, etc.
ZW horizontal self-priming sewage pump is widely used as sewage pump, impurity pump to transport sewage or wastewater containing large particles and long fiber etc. impurities.ZW self-priming pump is suitable for chemical industry, petroleum, pharmaceutical, mining, papermaking, fiber, pulp, textile, food, power plant and municipal sewage engineering, public facility sewage disposal, river pond culture and other industries. It is an ideal impurity pump for pumping the liquid with solid particles, fiber, slurry and mixed suspension.
Pump material: cast iron or stainless steel
Pumped solid diameter: The diameter of suspended particles is 60% of the pump diameter, and the fiber length is 5 times of the pump diameter.
Suction height:4.5m-5meters
