Scroll vacuum pumps Scroll Vacuum Pump consist of both a set and an orbiting scroll. As the orbiting scroll techniques, voids are created at the inlet of the pump, drawing in the gas. As the rotor further moves, the gas can be 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. Furthermore, the leak-tight design aids in preventing contamination of the pumped gas by ambient atmosphere. Maintenance is limited to changing the scroll tip seals which may be easily carried out by the operator and with no need for special tools.
