Scroll vacuum pumps 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 additional moves, the gas is certainly steadily compressed until it is discharged to atmosphere at the pump exhaust.

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