Scroll vacuum pumps contain both a fixed and an orbiting scroll. As the orbiting scroll moves, voids are manufactured at the inlet of the pump, drawing in the gas. As the rotor additional moves, the gas is usually steadily compressed until it really 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 Scroll Vacuum Pump separated from the compression chamber therefore no contamination of the pumped gas is possible. In addition, the leak-tight design helps prevent contamination of the pumped gas by ambient air flow. Maintenance is bound to changing the scroll tip seals which can be easily performed by the operator and without the need for special tools.
