Self-priming Sewage Pump Description

The ZW Self-Priming Non-Clogging Sewage Pump combines self-priming and non-clogging capabilities in one unit. Featuring a unique axial reflux outer recirculation design through the pump body and impeller passage, this pump operates without the need for a bottom valve or irrigation water. It can handle liquids containing large particles and solid impurities up to five times the outlet diameter, with a self-priming height of up to 5 meters. It is ideal for replacing all types of submersible and liquid-type sewage pumps. Widely used in industries such as chemical, electrical, mining, paper, textile, printing and dyeing, environmental protection, food, municipal sewage, and more, the ZW sewage pump excels in pumping solid particles, fibers, pulp, and mixed suspensions.
