A rotary lobe vacuum pump is a positive displacement pump that uses rotating lobes to generate vacuum.

Two three-bladed rotary lobes are mounted in parallel within the housing. They operate in opposite directions. The pumped medium is trapped through the rotation of the lobes, compressed, and transported to the outlet. The minimal clearance between the lobes and the housing optimizes the internal seal.

The oil-free operation makes rotary lobe vacuum pumps ideal for applications requiring dry vacuum environments. They are used for various applications in industries that require reliable vacuum generation, ranging from wastewater treatment to food processing.
