Technical information. Selecting Centrifugal Pumps. 2 Pump Types. Typical selection criteria for centrifugal pumps are their design data (flow rate or capac­ ity Q The input power P of a pump (also called brake horsepower) is the mechanical power in kW or W taken by the shaft or coupling. Pumps type TCK, TBK and TBAK create a high magnetic field.
