Votek VPS is a single-stage twin-screw vacuum pump. A pair of screw rotors rotate in the cavity and are compressed and transported to the exhaust port. During the compression process, the screw rotors do not contact each other, nor do they contact the cavity. No lubricating oil or working fluid is required for the compression chamber. The cooling method can be either direct water cooling or

Technical description

1. Inhalation efficiency (increased 15%).

2. Exhaust efficiency improvement (2-stage variable, continuously variable frequency).

3. Limit pressure: 1*10-2torr (torr).

4. The exhaust temperature decreases 50%.

5. Electricity consumption is reduced by 30%.

6. Do not use oil and water, will not cause oil and water pollution.

7. Low power consumption, low noise, low vibration, good dynamic balance, no inertial force, and high-speed operation.

8. The design structure is simple, easy to maintain, low maintenance cost and long life.

9. Wide application range and high vacuum performance.

10. The service life is long, and the gas contact parts are all coated with polytetrafluoroethylene, nickel and Hastelloy (some processes can choose special materials to solve the corrosion problem).

11. Lip seal and mechanical seal and other sealing methods to meet different process applications.

12. Rare lubrication is adopted before and after to improve bearing durability.
