Pump Types CENTRIFUGAL Centrifugal pump design is the most typical for Fire Pumps and Auxiliary Pumps in modern fire apparatus and its proven design has been used in fire apparatus for well over a century. In a basic centrifugal pump, typically a single casing, water enters through the pump inlet into the center (eye)
Centrifugal pumps are one of the most common types of pumps used in various industries for transferring fluids from one place to another. The working principle of a centrifugal pump is based on the centrifugal force, from which it derives its name. In this article, we will explore the basic working principle of centrifugal pumps, their components, and their applications.

Working Principle of Centrifugal Pump
A centrifugal pump works by converting mechanical energy from a motor into kinetic energy in the form of velocity and pressure in the pumped fluid. The pump consists of an impeller that rotates at high speeds, creating a centrifugal force that propels the fluid towards the outer edges of the impeller. As the fluid moves radially outward, it gains velocity and pressure due to the centrifugal force.
The fluid enters the pump through the suction inlet and is directed towards the center of the impeller. The rotating impeller then imparts kinetic energy to the fluid, increasing its velocity. The fluid is then forced out through the discharge outlet at a higher pressure than the suction pressure. This pressure difference allows the fluid to be transferred from one location to another.
Components of a Centrifugal Pump
- Impeller: The impeller is the rotating component of the pump that imparts energy to the fluid.
- Casing: The casing surrounds the impeller and helps guide the flow of the fluid.
- Suction Inlet: The point where the fluid enters the pump.
- Discharge Outlet: The point where the fluid exits the pump at a higher pressure.
- Shaft: The shaft connects the motor to the impeller and transmits the rotational energy.
Centrifugal Pump vs. Peripheral Pump
While centrifugal pumps work on the principle of centrifugal force, peripheral pumps operate on a different mechanism. In a peripheral pump, the fluid is transferred using the action of rotating impeller blades that push the fluid around the edge of the impeller. This results in a different flow pattern and pressure characteristics compared to centrifugal pumps.
Centrifugal Pump Inlet and Outlet
The suction inlet of a centrifugal pump is where the fluid enters the pump, while the discharge outlet is where the fluid exits the pump at a higher pressure. Proper positioning and sizing of the inlet and outlet are crucial for the efficient operation of the pump and to prevent cavitation, which can damage the pump.
Applications of Centrifugal Pumps
Centrifugal pumps are widely used in various industries for a range of applications, including:
- Water supply and distribution
- HVAC systems
- Chemical processing
- Petroleum refining
- Wastewater treatment
- Agriculture
The main parts of the Centrifugal Pump are: 1. Impeller 2. Casing 3. Backplate 4. Suction & Discharge Nozzles 5. Suction pipe 6. A foot valve 7. Strainer 8. Suction nozzle or suction
A lantern ring is a perforated hollow ring located near the center of the packing box that receives relatively cool, clean liquid from either the discharge of the pump or from an external source and distributes the liquid uniformly around the shaft to provide lubrication and cooling. The fluid entering the lantern ring can cool the shaft and packing,Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid . See more
