Scroll vacuum pumps consist of both a set and an orbiting scroll. As the orbiting scroll movements, voids are manufactured 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 Scroll Vacuum Pump provides 100% oil-free procedure as it does not require any lubrication. The bearings are separated from the compression chamber so no contamination of the pumped gas is possible. In addition, the leak-tight design aids in preventing contamination of the pumped gas by ambient surroundings. Maintenance is limited to changing the scroll tip seals which can be quickly completed by the operator and without the need for special tools.
