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.
