Scroll vacuum pumps contain both a set 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 further moves, the gas can be steadily compressed until it is discharged to atmosphere at the pump exhaust.
The scroll pump design provides 100% oil-free Scroll Vacuum Pump operation as it will 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 atmosphere. Maintenance is bound to changing the scroll suggestion seals which may be quickly performed by the operator and without the need for special tools.
