Description: Representation of the pump head height as a function of the flow rate; Name: Plant (NPSH) characteristic curve
Description: representation of the pump head plotted against the flow rate; Name: installation NPSH curve
Description: the pressure whose value is equal to the algebraic difference between the absolute pressure and the atmospheric pressure. To this end, the overpressure for a pressure room can, for example, be negative with underpressure or under vacuum; Name: Max. overpressure of the shaft seal
