Scroll Vacuum Pump Scroll vacuum pumps consist of 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 additional moves, the gas is 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 so no contamination of the pumped gas can be done. In addition, the leak-tight design aids in preventing contamination of the pumped gas by ambient surroundings. Maintenance is 
limited to changing the scroll suggestion seals which may be very easily completed by the operator and without the need for special tools.
