Description: Design flow rate in the pump inlet port divided by the inlet cross-section of the pump; Name: average design speed in the inlet
Description: rated flow at pump inlet connection divided by the inlet area of the pump; Name: mean rated velocity at inlet
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
