Description: Minimum NPSH for a pump achieving a specified performance at the specified rate of flow and speed (occurrence of visible cavitation, increase of noise due to cavitation, appearance of head or efficiency drop, head or efficiency drop of a given amount, etc.).; Name: NPSHR
Description: minimum NPSH-value at the pump inlet connection required to give the rated or operating performance at the specified conditions; Name: Net positive suction head required
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
