Selecting the right type of impeller is essential for the pump's performance. For instance, if a pump is expected to handle a high volume of sewage containing large solids, an open impeller would be more effective. Conversely, if the pump is mainly handling gray water with minimal solids, a semi-open or enclosed impeller would suffice.

8. Pump Backplate

Function: Liners protect the pump casing from the abrasive action of the slurry.

   - Reach out to the pump manufacturer’s technical support team for assistance in confirming your selection.

The pump casing encases the impeller and provides a pathway for the slurry to flow. It is structured to withstand high-pressure conditions and is often made from durable materials such as cast iron or high chromium content alloys. The casing must also be designed to minimize wear caused by the abrasive nature of the slurry, making material selection critical for long-term performance.

4. Shaft Sleeves

Materials: Typically made from the same material as the casing or other wear-resistant materials.
