Horizontal sewage pump
Horizontal sewage pumps are mainly used to transport urban sewage, feces, or liquids containing impurities such as fibers, paper scraps, and solid particles.
Horizontal sewage pump
The P and ZW type direct-coupled self-priming non-clogging sewage pumps integrate self-priming and non-clogging sewage discharge. They employ an axial backflow external mixing design and, through a unique design of the pump body and impeller flow channel, can operate like a regular self-priming clean water pump without requiring a foot valve or priming, while also capable of pumping liquids containing particulate solids and long fibrous impurities. This pump features a direct-coupled structure, characterized by its simplicity, compactness, low vibration, excellent self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and convenient use and maintenance. It is widely applicable to municipal sewage projects, river and pond aquaculture, light industry, papermaking, textiles, food, chemicals, power generation, fiber, pulp, and mixed suspension media, making it an ideal impurity pump.
