Elmo Rietschle’s dry running rotary vane pumps, compressors, and pressure-vacuum pumps deliver oil-free, environmentally friendly performance with exceptional reliability. Compact yet powerful, they are tailored to meet the demands of diverse industries with precision and efficiency. Browse our product range below to find the best fit for your needs.
Elmo Rietschle’s dry running rotary vane pumps are engineered to deliver robust, oil-free performance for vacuum, pressure, or combination applications. Designed for reliability and environmental sustainability, these pumps eliminate the need for lubricating oil, ensuring clean and contamination-free operation across diverse industries.
The innovative design features include:
The dry running rotary vane pumps operate on the principle of pressure increase through volume reduction. As the rotor turns within the cylindrical housing, vanes slide in and out of slots, creating cells that draw air in, compress it, and discharge it through the outlet port. This oil-free design ensures quiet, reliable, and eco-friendly operation.

Elmo Rietschle’s dry running rotary vane pumps are trusted across industries for their versatility, efficiency, and oil-free operation. Designed to adapt to challenging industrial environments, they excel in the following applications:
Dry running rotary vane pumps operate on the principle of pressure increase through volume reduction.
Inside the cylindrical housing, a rotor is positioned eccentrically, creating tight clearances with the cylinder walls. Vanes slide in and out of rotor slots due to centrifugal force, forming cells that change in volume during rotation. As air enters through the inlet port, the cell achieves its maximum volume. As the rotor turns, the cell's volume decreases, compressing the air until it reaches the outlet port, where it is discharged.
In vacuum pumps, the cell creates decreasing pressure relative to atmospheric pressure to generate suction. In pressure-vacuum models, additional inlet ports enable simultaneous vacuum and pressure generation, with the ratio between the two controlled by the design and configuration of the inlet ports. This allows precise adjustment of vacuum and pressure capacities to suit specific industrial applications.In pressure-vacuum models, additional inlet ports enable simultaneous vacuum and pressure generation, with the ratio between the two controlled by the choice of inlet port design. These innovative features make Elmo Rietschle’s dry running rotary vane pumps versatile and adaptable to a wide range of industrial applications.
The design ensures quiet operation, minimal maintenance, and optimized efficiency, making these pumps a reliable choice for industries seeking oil-free, environmentally friendly solutions.
