A centrifugal pump is defined as a rotodynamic pump that makes use of a rotating impeller to raise the rate of a fluid. This type of equipment might seem complicated if it is your first encounter with it. A centrifugal pump is one of the easiest types of equipment.
Its primary function is to convert the energy of an engine, or an electric motor, into kinetic energy or velocity. This will create pressure to force the fluid out. The energy changes occur in two main centrifugal pump parts: the volute and impeller. The volute, which is inactive, converts kinetic energy into pressure. The impeller, on the other hand, is the revolving component that converts the driver energy into kinetic energy.
What It Does with Centrifugal Force
When liquid is pumped into the impeller's eye, it creates centrifugal force. The impeller rotates and instantly turns the liquid into hollows. This imparts centrifugal acceleration, vanes outward, and instantaneously spins the impeller. As the liquid exits the impeller's eye, a low-pressure zone is created that allows more liquid to flow into the inlet.
Multistage Centrifugal pumps
Multistage centrifugal pumps contain two or more impellers. These impellers may be mounted on different shafts or similar shafts. A multistage basically has two essential functions: it ejects a lot of liquid and generates a high head.
The impellers must be mounted on a similar shaft in order to achieve a high head. Installing impellers on different shafts can result in a large amount of liquid being released.
