  • Discharge Pressure | Double Diaphragm Pumps

    2017-5-4 · Discharge Pressure All air operated diaphragm pumps are able to operate up to 0.5 bar (5 meters) below the drive air pressure. This means that if the pump is rated to accept 8 bar air drive pressure, the pump will transport fluids with a specific gravity of 1 (water) and viscosity of 1 (water) to 75 meters static height.
