Scroll vacuum pumps contain both a fixed and an Scroll Vacuum Pump orbiting scroll. As the orbiting scroll techniques, voids are manufactured at the inlet of the pump, drawing in the gas. As the rotor further 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 procedure as it does 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 helps prevent contamination of the pumped gas by ambient surroundings. Maintenance is limited to changing the scroll suggestion seals which can be easily done by the operator and without the need for special tools.
