b. Impeller Design:
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.
Wear plates are installed within the pump casing to protect the surfaces from the erosive wear caused by the particles in the slurry. These plates can be easily replaced when worn, allowing for maintenance without needing to replace the entire pump. Some wear plates are designed to be adjustable to optimize the pump's performance by fine-tuning the clearance around the impeller.
