self priming pump

The self-priming pump is a type of centrifugal pump that features a compact structure, convenient operation, smooth running, easy maintenance, high efficiency, long service life, and strong self-priming ability. It does not require the installation of a bottom valve in the pipeline, and before operation, only needs to ensure that a certain amount of liquid is stored inside the pump body. Different liquids can be handled by self-priming pumps with different materials. The working principle of the self-priming pump is to fill the pump casing with water (or the pump casing itself contains water) before starting the pump. After starting, the high-speed rotation of the impeller causes the water in the impeller channels to flow towards the volute casing, creating a vacuum at the inlet, which opens the non-return valve, allowing the air in the suction pipe to enter the pump and reach the outer edge through the impeller channels.

Self Priming Trash Pump is designed for the treatment of municipal and industrial sewage, as well as for stage treatment and concentrated treatment systems for various sewage applications. It has earned the title of the "King of Self-Priming Sewage Pump" and is recognized as the most ideal new-generation sewage product on the market.
