Slurry Pump Expeller

Pump Impeller

The pump expeller is an open impeller, which is installed on the opposite side of the back cover of the impeller in the opposite direction of the shaft. The main function is to balance the axial force and reduce the pressure in the sealed cavity.
When the pump is running and the shaft is rotating. The liquid in the propeller will rotate together. The rotating liquid will generate an outward centrifugal force that resists the liquid flowing to the mechanical seal and reduces the pressure. Also, prevent solids from flowing into the mechanical seal. It reduces the wear of the mechanical seal abrasive block, thereby extending its service life.
However, the use of ejector seals also has disadvantages. The propeller also consumed 3% of the energy. But we can reduce this consumption through reasonable design.
The slurry pump expeller is also an important part of the slurry pump. It can not only help seal the pump but also reduce centrifugal force. The design and material of the propeller are critical to its service life because it is also one of the wet components.
