Scroll vacuum pumps consist of both a set and an orbiting scroll. As the orbiting scroll movements, voids are manufactured at the inlet of the pump, drawing in the gas. As the rotor additional moves, the gas is steadily compressed until it is discharged to atmosphere at the pump exhaust.

The scroll pump design provides 100% oil-free procedure as it will not require any lubrication. The bearings are separated from the compression chamber therefore no contamination of the pumped gas can be done. In addition, the leak-tight design aids in Scroll Vacuum Pump preventing contamination scroll vacuum pump201909161349237135848of the pumped gas by ambient air flow. Maintenance is limited to changing the scroll tip seals which may be very easily done by the operator and without the need for special tools.
