The ZW type self suction and non clogging sewage pump is developed by engineering technicians from Shanghai Blue Ocean Pump Industry, who have absorbed domestic and foreign technology and combined it with the actual situation of China's mechanical and electrical industry. Through a novel structure of impeller and pump body, the pump combines self suction and non clogging sewage. It can be used like ordinary water self suction pumps without the need for bottom valves or irrigation water, and can also suck pollutants containing large particle solid blocks, fibers, sediment, waste ore impurities, fecal treatment, and all engineering sewage, completely reducing the labor intensity of workers. Moreover, it is easy to use, move, install, with minimal maintenance and stable performance, and is highly favored by users.
The pump mainly consists of a pump body, impeller, rear cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water adding valve, inlet and outlet pipes, etc. Its working principle is that there is a liquid storage chamber inside the pump body, and it is connected to the pump working chamber through the reflux hole above and the circulation hole below, forming an axial reflux external mixing system of the pump. After the pump stops working, there is already a certain volume of liquid stored in the pump chamber. When the pump starts, the stored liquid inside the pump is returned to the working chamber through the grid of the gas-liquid separation pipe under the action of the impeller, and the gas is discharged from the pump, forming a certain degree of vacuum inside the pump and achieving self suction.
ZW series non clogging self suction 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 blade chamber, and the pressurized water chamber is connected to the impeller chamber. When the impeller rotates, the liquid inside the pump generates strong axial eddy currents, causing a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressurized water chamber, so its flow channel is completely unobstructed, and its drainage effect is very efficient.
The ZW series non clogging self suction sewage pump is widely used in industries such as municipal sewage engineering, light industry, papermaking, textile, food, chemical industry, electricity, petroleum, mining, and river pond aquaculture.
The ZW series non clogging self suction sewage pump is widely used in industries such as municipal sewage engineering, light industry, papermaking, textile, food, chemical industry, electricity, petroleum, mining, and river pond aquaculture. It is currently an ideal impurity pump for pumping solid particles, fibers, slurries, and mixed suspension media in China. The design is precise and the quality is excellent. This self suction sewage pump produced by Shanghai Lanhai Pump Industry is the best choice for many buyers.
