Description: relationship between the total head of the pump and the rate of flow at given operating/rated conditions of speed and liquid; Name: pump head capacity curve
Description: pump H(Q) curve where the maximum head and shut-off head are coincidental, and the total head declines continuously as the rate of flow increases; Name: Pump H(Q) curve
Description: voltage which, together with the rated operating current, determines the use of the device and to which the various tests and the use categories refer. With single pole devices the rated rated operating voltage is generally the voltage over the pole. With multi-pole devices it is generally given as chained voltage; Name: Operating voltage
