The robustly designed of Becker U Series rotary vane pumps excel in vacuum applications with higher pressure differences. A rotor, eccentrically mounted with slots, rotates within a cylindrical housing. Precision-fitted sliding vanes move within the slots, creating separation between individual working chambers. In contrast to dry-running rotary vane pumps, oil-lubricated pumps not only provide lubrication but also seal the working chambers with the transported oil. This sealing capability allows the pumps to achieve a fine vacuum, making them ideal for applications requiring high vacuum levels.
