ZWPB stainless steel explosion-proof and unobstructed self-priming sewage pump usage precautions:

The shorter the suction pipeline, the better, not exceeding 10M.
If this pump is used to pump thick and viscous slurry, the pump chamber needs to be cleaned to prevent sediment from being left inside the pump.
3. When using a self-priming pump for the first time, the pump chamber still needs to be filled with water.
After 3000 hours of regular operation, the water pump needs to be disassembled, inspected, and maintained. If necessary, vulnerable parts that are no longer suitable for use should be replaced.
5. This pump can be customized with a direct connection type, which has high concentricity, enhanced stability, and is more economical, but maintenance may be a bit troublesome.
6. Environmental temperature ≤ 45 ℃, medium temperature ≤ 60 ℃.
7. The pH value of the medium is 6-9 for cast iron pumps and 1-14 for stainless steel self-priming pumps.
8. The particle diameter is 60% of the diameter of the self-priming pump, and the fiber length is 5 times the diameter.
9. The total weight of impurities in the medium shall not exceed 15% of the total weight of the medium, and the specific gravity of the medium shall not exceed 1240 kilograms per cubic meter.

ZWPB stainless steel explosion-proof non clogging self-priming sewage pump product introduction:

ZW type unobstructed self-priming sewage pump, also known as solid-liquid pump or impurity pump. It integrates the functions of a self-priming pump and a non clogging sewage pump, using an axial reflux external mixing type with a unique hydraulic design. The impeller is enclosed in a separate impeller chamber, connected to a pressurized water chamber. When the impeller rotates, the liquid in the pump generates a strong axial vortex effect, causing a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressure chamber, so its flow channel is completely unobstructed, and its sewage discharge effect is unparalleled by other self-priming sewage pumps. Through the unique design of the pump body and impeller flow channel, it is possible to suction and discharge liquids containing large solid particles and long fiber impurities without the need for bottom valves and inlet water like a typical self-priming water centrifugal pump.

Product advantages:

Compared with similar domestic products, the ZW type non clogging self-priming sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy use and maintenance.
The ZW type unobstructed self-priming sewage pump is the first of its kind in the sewage pump series in China. All technical performance indicators are leading domestically and have reached the international advanced level, with broad application markets and development prospects.

Product Usage:

ZW type non clogging self-priming sewage pump can be used without installing a bottom valve like a general self-priming water pump, and can also suck and discharge engineering wastewater containing large solid particles, long fibers, sediments, waste impurities, feces treatment, and all other materials. It can be widely applied to industries such as municipal sewage engineering, light industry, papermaking, textile, food, chemical industry, electric power, petroleum, mining, and river pond aquaculture. It is currently a very suitable impurity pump for pumping solid particles, fibers, slurries, and mixed suspensions in China.
