What is a Pump Casing?

2025-07-12

The pump casing is the main component of the pump, located outside the pump, used to contain and guide the fluid.


The pump casing is usually a closed metal shell that is used to contain the rotating parts and other important structures of the pump. During the operation of the pump, it plays a role of protection and support to ensure the normal operation of the pump.

Pump Casing

The main function of the pump casing is to contain and guide the fluid, ensuring that the fluid flows in from the inlet of the pump and flows out from the outlet after being pressurized by the pump. In addition, the pump casing also plays a supporting and fixing role, so that the internal parts of the pump remain stable when rotating at high speed. The design of the pump casing also takes into account the functions of heat dissipation and noise reduction.


The pump casing is made of wear-resistant and corrosion-resistant materials, such as cast iron or stainless steel. Its structure varies depending on the type and purpose of the pump, but it usually includes designs such as inlet, outlet, and internal flow channels. The inlet and outlet are used for the entry and exit of the fluid, and the internal flow channel ensures that the fluid can flow smoothly through various parts of the pump.


The pump casing is an important supporting structure of the pump, and its quality and design directly affect the performance and service life of the pump. Therefore, when selecting and using a pump, it is necessary to consider the material, structure and performance of the pump casing to ensure that it can meet specific engineering requirements.


The pump casing is a key component that protects and supports the internal parts of the pump, ensuring that the fluid can flow smoothly and be pressurized. When selecting and using a pump, it is very important to consider the pump casing.
