Function: The expeller and expeller rings work together to reduce the pressure and minimize leakage from the pump.

b. NPSH (Net Positive Suction Head):

The impeller is a rotating component within the pump that transfers energy from the motor to the slurry. It plays a significant role in creating the flow and pressure necessary to move the slurry through the system. Impellers for slurry pumps are typically heavier and more robust than those used in standard pumps to withstand the harsh conditions encountered in abrasive applications. Their design can vary, with options for different shapes and sizes to accommodate specific types of slurries.

Wear Factors: Continuous contact with the slurry and seals can cause wear on the shaft sleeves.
