ZW series self-priming sewage pump sets have the advantage of self-priming and non-clogging, can be installed without bottom valve like clean water self-priming pump, but also pumping dirty water with large particles, dirt, fibers , abandoned mine sediment impurities, and other works of sewage treatment and waste material.
ZW series self-priming sewage pump sets have the advantage of self-priming and non-clogging, can be installed without bottom valve like clean water self-priming pump, but also pumping dirty water with large particles, dirt, fibers , abandoned mine sediment impurities, and other works of sewage treatment and waste material, completely reducing labor intensity, and can make mobile type, easy installation, minimal maintenance, stable performance.
1. ZW series self-priming non-clogging sewage pump, is mainly composed of pump body, impeller, back cover, mechanical seal, bearing, inlet valve, water valves, suction and discharge pipes, etc.
2. In the pump body has a reservoir chamber, which is connected with the top back-flow hole and bottom circulation hole and pump working chamber, interlinked to form the axial pump back outer recirculation system. When pump stops working, the pump cavity has a certain volume of the liquid reservoir. When the pump starts, under the action of the impeller, the air is rounded up with the liquid through the gas-liquid separator, and the liquid back into the working chamber, while the gas is discharged from the pump, so as to form a certain vacuum in the pump chamber, to achieve self-absorption effect.
ZW type self-priming non-clogging sewage pump can be widely used in municipal sewage works, Hetang farming, light industry, paper making, textile, food, chemical, electrical and other industries, is the best trash pump for pumping fiber, pulp and other chemical media mixed with suspension.

During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.
The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
Diaphragm pump is a new type of conveying machinery that can convey various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. Diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel.
