A Pump is generally used to induce flow or raise the pressure of a liquid. Centrifugal pumps are a category of Dynamic pumps. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes. The basic centrifugal pump theory of working is explained in the below video and the working stages illustrated below.
Centrifugal Pump Working Principle / Stages:
- Liquid enters the pump casing at the impeller eye. – Velocity energy is imparted to the liquid by means of the centrifugal force produced by rotation of the impeller and the liquid is radially pushed out towards the impeller periphery.- The velocity energy of liquid is converted to pressure energy by directing it to an expanding volute design casing in a volute type centrifugal pump or diffusers in a turbine pump.
