Definition - What does Centrifugal Pump mean?
A centrifugal pump is a machine that imparts velocity to a liquid using rotation and then converts the velocity into flow. The components of a centrifugal pump include the impeller, casing and pump shaft mounted on bearings. This pump finds use in the oil industry and is used for handling and mixing of oilfield fluids. There are different types of centrifugal pumps such as electric submersible pumps used for separating water and oil to re-inject the water into the reservoir without bringing it to the surface.
These pumps are capable of handling low viscosity and dirty liquids if they are free from vapor, air and excess solid particles.
Trenchlesspedia explains Centrifugal Pump
The impeller in centrifugal pumps is the hydraulic component that rotates and imparts the required velocity to the liquid that is sucked in. The casing captures the velocity that the impeller imparts to the liquid and directs it to the pump exit. The impeller is designed with one or more vanes that extend from the center to its outer diameter. The turning of the impeller creates a centrifugal force that imparts rapid movement of the liquid from the center along the vanes to the outer diameter at high velocity.
The impeller can be closed, semi-closed or open type depending on what type of liquid is to be pumped.
