The diaphragm pump unit is powered by compressed air and has 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 up to 70 meters of water head.
The pump is non-metallic and the diaphragms, balls, ball seats, and o-rings are made of teflon, polypropylene and viton 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.
