Centrifugal Pumps: Basic Concepts of Operation

2015-10-8  centrifugal pump is one of the simplest pieces of equipment in any process plant. Its purpose is to convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. The energy changes occur by virtue of two main parts of the pump, the impeller and the volute or diffuser. The impeller is the rotating part that

PUMPS DON'T SUCK! And Other Centrifugal Pump Basics

2015-2-12  Centrifugal pumps move fluid by using centrifugal force to generate velocity of the liquid. Fluid enters the pump through the suction nozzle, into the eye of the impeller. The impeller vanes catch the fluid and rotate it, both tangentially and radially until it exits the pump on the discharge side.
