About the series

Technology and features

Operating principle

Scroll vacuum pumps compress the gas between two interleaved scrolls: one scroll is fixed, the other orbits, so that the gas is conveyed from the outside to the inside towards the outlet in chambers that become smaller and smaller. The pump chamber is oil-free, and the pumps run quietly and with low vibration.

The technology page shows the operating principle with an interactive drawing: Scroll vacuum pumps.
