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: permanent operation, short-term operation or periodic operation characterized by one of more loads and which remains unchanged during a certain period, or, in the case of non-periodic operation, where the load and speed generally change within the permissible operating range; Name: Operation type time sequence of the drive
