Scroll vacuum pumps contain both a set and an orbiting scroll. As the orbiting scroll techniques, 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 separated from the compression chamber therefore 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 Scroll Vacuum Pump changing the scroll suggestion seals which can be quickly done by the operator and with no need for special tools.
