Structural components of a centrifugal pump

Impeller: The core component that generates centrifugal force through rotation. It can be classified into closed, semi-open, and open types based on its structure.
Pump casing: Collects the liquid and guides it to the outlet; usually designed as a volute casing to optimize energy conversion.
Pump shaft: Connects the motor and impeller to transmit power.
Sealing device: Prevents liquid leakage; common types include packing seals and mechanical seals.
Bearings: Support the pump shaft to reduce friction.
