Scroll vacuum pumps contain both a fixed and an orbiting scroll. As the orbiting scroll techniques, voids are created at the inlet of the pump, drawing in the gas. As the rotor additional moves, the gas is definitely steadily compressed until it is discharged to Scroll Vacuum Pump 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 can be done. In addition, the leak-tight design helps prevent contamination of the pumped gas by ambient atmosphere. Maintenance is bound to changing the scroll suggestion seals which can be easily done by the operator and with no need for special tools.
