Description: Power consumption due to friction in bearings and shaft seals at certain working conditions of the pump; Name: mech power losses of pump
Description: power absorbed by friction in bearings and shaft seal at given operating conditions of the pump; Name: pump mechanical power losses
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
