Self-Priming Pump

The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a foot valve in the pipeline, and only need to ensure that the pump body is stored with quantitative fluid extraction before working. Different liquids can be self-priming pumps made of different materials. Self-priming pumps work by filling the casing with water (or containing water in the casing) before the pump starts. After starting, the high-speed rotation of the impeller makes the water in the impeller channel flow to the vortex shell, and then the inlet forms a vacuum, so that the water inlet backstop door is opened, and the air in the suction pipe enters the pump, and reaches the outer edge through the impeller channel. Most of the self-priming pumps are matched with internal combustion engines and are installed on movable trolleys, which are suitable for field operations. Features::

1. Strong sewage discharge capacity: the special impeller anti-clogging design ensures that the pump is efficient and clogging-free.

2. High efficiency and energy saving: using excellent hydraulic model, the efficiency is 3~5% higher than that of general self-priming pumps.

3. Good self-priming performance: the self-priming height is 1 meter higher than that of the general self-priming pump, and the self-priming time is shorter.

Product use: ZW self-priming non-clogging sewage pump is suitable for chemical, petroleum, pharmaceutical, mining, papermaking, fiber, pulp, textile, food, power plant and municipal sewage engineering, public facilities sewage, river pond aquaculture and other industries.
