Centrifugal Pump
A centrifugal pump produces a head and flow by increasing the velocity of a fluid through the pump via a rotating vane impeller.
Centrifugal Pumps
The rotating impeller increases pressure and moves the fluid. The fluid enters the pump close to the rotating axis (or eye) of the impeller and enters the cavities between the vanes of the impeller.
As the pump impeller rotates, the fluid flows outward from the central axis into a chamber where it is discharged. As the fluid leaves the the axis of the impeller, a low pressure area is created and this draws more liquid into the pump inlet.
Centrifugal pump types include radial, axial and mixed flow and can be categorised into the following groups.
- End suction pumps
- In-line pumps
- Double suction pumps
- Vertical multistage pumps
- Horizontal multistage pumps
- Submersible pumps
- Self-priming pumps
- Axial-flow pumps
Multistage Centrifugal Pump
A Centrifugal Pump with two or more impellers is called a Multistage Centrifugal Pump. The impellers can be mounted on a single or multiple shafts and can be connected to increase pressure or flowrate.
Where to use a Centrifugal Pump
A Centrifugal pump is commonly used to move thin fluids like water, juice or thin oils.
