Materials: High-quality bearings are used to withstand the operational stresses.

   - Ensure the pump has adequate NPSH available to avoid cavitation.

Function: Bearing assemblies support the pump shaft and ensure smooth operation.

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.

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.

Function: Shaft sleeves protect the pump shaft from the slurry and the mechanical seals.
