Casing/Housing in Centrifugal Pumps

Casing in centrifugal pump serves to seal off the inside of the pump to the atmosphere to prevent leakage and retain pressure. In the case of centrifugal pumps, they surround the pump rotor which transmits energy to the fluid handled via the impeller mounted on the rotating shaft.

The term “casing” is generally used to describe the component that “contains” the pump. In practice a pump’s casing has five functions:

1. It will Provide pressure containment.

2. Incorporate the collector, either as an integral part of the casing or as a separate piece.

3. Permit rotor installation and removal.

4. Support the pump or provide a structural connection to the pump’s support.

5. Maintain alignment of the pump and its rotor under the action of pressure and reasonable piping loads.

There are three types of casing in a centrifugal pump are described below

1. Volute casing

2. Vortex casing

3. Casing with guide blades

In our EG-250 Series Centrifugal pump, we use Vortex casing.

Vortex casing is a casing in which circular chamber is provided between the casing and the impeller.

Vortex casing is helpful to increase pump efficiency by reducing eddies formation to a considerable extent.

EG-250 Centrifugal pump casings normally are made of casting iron material, casings can also be produced in stainless steel material or high Chrome material as per clients requests.
