b. NPSH (Net Positive Suction Head):

Impellers are the rotating parts of sewage pumps that convert rotational energy from the motor into kinetic energy within the fluid. This transformation occurs through the design of the impeller blades, which are shaped to create a flow of water, pushing it outwards through the volute or the casing. The design of the impeller directly affects the pump's efficiency, capacity, and performance.

Types:

b. Selection Software:

   - Verify that the pump operates efficiently at the desired operating point (usually within the best efficiency range).

Materials: Materials used for shaft sleeves include hardened stainless steel and ceramic-coated materials.

   - Volute Liners: Protect the pump casing in the volute section.
