The diaphragm pump unit is powered by compressed air and is a 1:1 pressure ratio design. The diaphragm pump operates under balanced conditions during the discharge stroke, which allows the unit to be operated at discharge heads over 75 meters of water head. The pump is non-metallic and all seals and ball valves are made of Teflon overlay, which makes the pump excellent for operating with all kinds of high or low viscosity oils, acids and chemicals. The (special) design ensures that the flow variation range is controlled by an air pressure regulating valve and an air/water separator including injection of lubrication in the air flow, which secures a safe, reliable and efficient supply of liquid
