One of the main advantages of propeller pumps is their simplicity and durability. Given their straightforward design, maintenance requirements are generally low, which is advantageous for organizations looking to minimize operational costs. Furthermore, these pumps can be made from various materials designed to resist corrosion, extending their lifespan even in harsh environments.

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.

-
Function: Seals prevent slurry from leaking out of the pump and protect the internal components.
-
- Packing Seals: Use a packing material to create a seal around the shaft.

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.
