In firefighting systems, propeller pumps also play a crucial role. They provide the necessary pressure and volume of water needed to combat fires effectively. Their capability to move large quantities of water quickly makes them a reliable choice for fire departments, particularly in high-risk areas where rapid response is critical.

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.

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.

 3. Consider Material and Design

Wear Factors: Impellers are subject to high levels of wear due to the abrasive nature of slurries.Materials: Common materials for impellers include high-chrome alloys, natural rubber, and polyurethane.
