Description: pressure of the atmosphere at a specified place and time; Name: pressure of the athmosphere
Description: Mean absolute pressure of the atmosphere measured at the place of installation of the pump ; Name: Atmospheric pressure
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
