Scroll vacuum pumps contain both a set and an orbiting scroll. As the orbiting scroll techniques, voids are Scroll Vacuum Pump 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 is possible. Furthermore, the leak-tight design helps prevent contamination of the pumped gas by ambient surroundings. Maintenance is bound to changing the scroll suggestion seals which may be quickly done by the operator and without the need for special tools.
