Centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. Centrifugal pumps are the most common type of pump used to move liquids through a piping system. 
It is widely used in oilfield drilling mud system, as trip pump, measurement pump, charging pump, mixing pump, feeding pump. It can be used together with mixing hopper as a mixing unit, with trip tank as a trip pump/measurement pump, with mud pump as charging pump for mud pump, or as a transfer pump. It is ideal choice for drilling fluids transfer.
