Scroll vacuum pumps contain both a fixed 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 is certainly steadily compressed until it 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 Scroll Vacuum Pump pumped gas can be done. In addition, the leak-tight design helps prevent contamination of the pumped gas by ambient air flow. Maintenance is limited to changing the scroll tip seals which can be very easily completed by the operator and with no need for special tools.
