Centrigual Pumps: The Basics

LKH Exploded PicSome consider a centrifugal pump to be one of the most basic pieces of equipment.  The main purpose of the centrifugal pump is to convert the energy of an electric motor or engine into velocity or kinetic energy, and in turn convert it into pressure of a fluid that is being pumped.

The energy conversion takes place in the two key component parts of the centrifugal pump, that is in the impeller and volute.  The rotating component, which is the impeller, is responsible for converting the driver energy into kinetic energy, while the stationary component, the volute, is responsible for converting the kinetic energy into pressure.
