What is Suction Shell and Pressure Shell?

Question

Accepted Answer

Suction shell and pressure shell are components of a centrifugal pump.

Suction shell is the part of the pump that houses the impeller and creates a low-pressure area to draw in fluid.
Pressure shell is the part of the pump that contains the discharge nozzle and creates a high-pressure area to push out fluid.
The two shells are separated by the impeller, which rotates to move fluid from the suction shell to the pressure shell.
Suction shell is also known as the volute, while pressure shell is also known as the casing.
The design of the shells can vary depending on the specific application and fluid being pumped.
