Rotary Vane Vacuum Pumps

Becker’s robustly constructed rotary vane pumps utilise a positive-displacement operating principle. An eccentrically mounted rotor with slots rotates in a cylindrical housing driven by a totally enclosed, fan-cooled motor. The precisely sliding vanes move in the slots, driven to the cylinder wall by centrifugal force. Separate the individual working chambers are created by the separation between the vanes.

Both our oil-less respectively dry-running rotary vane and oil-lubricated rotary vane vacuum pumps are suitable for higher pressure differences in vacuum applications. There are many factors to consider when choosing a pump technology, but the first issue is always the vacuum level required for the process. Time at the desired vacuum level, potential contaminants, ambient conditions are just a few of the multitude of factors that must be considered when choosing a technology.

Oil-Free Rotary Vane Vacuum Pumps

Oil-free respectively dry-running rotary vane vacuum pumps are suitable for higher pressure differences in vacuum applications. Self-lubricating, carbon-graphite composite vanes contact the cylinder wall directly. This limits the vacuum level that can be achieved to 100 mbar absolute.

Oil-Lubricated Rotary Vane Vacuum Pumps

Oil-lubricated rotary vane vacuum pumps generate a fine vacuum, making them suitable for high vacuum applications. Fiberglass vanes and a thin film of oil on the cylinder wall in the working chamber seal the chamber from leaks. This seal gives the ability to attain vacuum levels as deep as 1 mbar absolute.
