VACUUBRAND four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases requiring very low vacuum and high flow rates. All parts in contact with pumped vapors or gases are made of aluminum, stainless steel and carefully selected plastics compatible with a wide range of applications with non-corrosive gases. The four-stage, "double-star" design provides the advantageous combination of high pumping speed and an outstanding ultimate vacuum down to 0.6 mbar. The highly flexible, fabric-reinforced double diaphragms made of FPM ensure extended operating life.
