Scroll vacuum pumps contain both a set and an orbiting scroll. As the orbiting scroll moves, voids are created at the inlet of the pump, drawing in the gas. As the rotor additional 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 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. Furthermore, the leak-tight design aids in preventing contamination of the pumped gas by ambient atmosphere. Maintenance is bound to Scroll Vacuum Pump changing the scroll tip seals which can be very easily completed by the operator and with no need for special tools.
