Mechanical Booster Pumps
Mechanical booster vacuum pumps are positive displacement pumps which use rotors or lobes to increase pressure differentials and boost the performance of a backing pump. This type of pump is best suited for industrial applications with high flow rates or varying pressures. These pumps operate without any oil, because of which they are widely used in industrial applications that require a clean and oil-free vacuum environment.
