Description: highest head of a pump if it is not reached atzero flow rate; Name: peak head
Description: Highest total head developed by a pump when this does not occur at a zero rate of flow; Name: Head at peak point
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
