▶️Introduction
Centrifugal pumps are used in many applications all over the world. The pump is ideal for pumping fluids with a low amount of suspended bodies e.g. water. The centrifugal pump is low maintenance, reliable and relatively cheap.

Operation
Liquid is drawn into the impeller and flows outwards away from the impeller eye due to centrifugal force. The change in cross sectional area of the impeller vanes and volute casing causes the velocity energy to be changed to pressure energy (Bernoulli’s principle).

PHYSICS DISCLAIMER :Centrifugal force is an imaginary force, only centripetal force is a true force, but it is beyond the scope of this video to clarify this concept further.
