Rotary Vane Pumps

Elmo Rietschle’s V-Series rotary vane pumps leverage decades of engineering expertise to deliver reliable, efficient, and versatile vacuum and compression solutions. Available in both oil-lubricated and dry running models, our pumps cater to diverse industrial needs while ensuring long up-time and minimal maintenance.


• Oil-Lubricated Pumps: These pumps utilize oil as both a lubricant and a sealing agent, ensuring smooth operation and reducing wear over time. The rotating vane mechanism creates suction and compression cycles, generating a powerful vacuum efficiently. This robust design makes them ideal for applications requiring consistent performance and extended service life.


• Dry Running Pumps: Designed to operate without oil lubrication, these pumps use a rotating vane mechanism to compress air or gas, creating vacuum or pressure. Their oil-free design eliminates maintenance concerns related to oil, making them perfect for applications requiring clean, dry, and contamination-free operation.

How Does a Rotary Vane Pump Work?

Oil-Lubricated Rotary Vane Pumps: These pumps operate using a rotating vane mechanism within a cylindrical chamber. The vanes slide in and out, maintaining contact with the chamber walls. Oil serves as a lubricant, sealing agent, and cooling medium, ensuring efficient operation and reduced wear. As the vanes rotate, they create varying chamber volumes, generating suction and compression cycles to produce vacuum. The result is a reliable and powerful vacuum solution for demanding industrial applications.


Dry Running Rotary Vane Pumps: Dry running pumps use a similar rotating vane mechanism but eliminate the need for oil lubrication. The vanes compress air or gas within the cylinder, generating vacuum or pressure. This oil-free design ensures clean, dry, and contamination-free performance, making it ideal for industries that prioritize environmental sustainability and clean operation.
