The centrifugal pump is mainly made up by the pump impeller and volute, the fluid indrawing from the mid impeller, and under the influence of centrifugal force, it get the power continuous ( kinetic energy and pressure energy ), then the fluid through the volute casing, one part of the fluid is transform into pressure energy and output. The below will analysis the work operation principle of the centrifugal pump.

Such analysis can help we have a deeper understanding of the drilling fluids centrifugal pump.The motion of the fluid in the centrifugal pump is quite complex, it mainly consist of tow kinds, one is the fluid moved with the impeller, the other is the fluid moved by the impeller cover from the entrance and exit. The motion state of the fluid is mainly decide by this two motions.
