The self-priming pump relies on the high-speed rotation of the impeller to pump the low-pressure zone in the self-priming pump. Therefore, the self-priming pump must ensure that the inlet pipe does not leak. That is to ensure that the outside air can not enter the inlet pipe. Otherwise, it will not only affect the pumping efficiency, but also cause severe vibration and noise when the pump is working...

Submersible pumps often encounter problems such as oil leakage, low lift, low speed, Impeller does not turn, and low flow. Submersible pumps are widely used in agricultural irrigation and domestic water supply. Due to the long-term submersible work of the pump body, coupled with poor water quality in some areas and insufficient maintenance experience, the failure rate is high...

There are many reasons for the water leakage of the pump,mainly because the mechanical seal leaks.

Mechanical seals are also called end seals. The pump has apair of end faces that are perpendicular to the axis of rotation. The end faceis kept in conformity with the other end by the cooperation of the auxiliaryseal under the action of the fluid pressure and the compensation of themechanical external elastic force. And slide relative to prevent fluid leakage.
