Description

The oil-free scroll vacuum pump is a highly efficient, compact, and clean vacuum solution, widely used across industries where strict oil-free requirements and high vacuum performance are essential. Its advanced design—comprising a pump head, motor, and machine base—ensures reliable performance with minimal maintenance.

Working Principle

The pump operates via the relative rotation of a movable and a fixed scroll disk, forming a crescent-shaped compression chamber. As the chamber volume decreases, gas is drawn in, compressed, and discharged through the exhaust port. The scroll disks do not contact each other, eliminating friction loss and ensuring quiet, efficient operation. The unique involute spiral design enables continuous suction and compression for consistent vacuum performance.

Main Features

  1. All oil-free: No oil return or oil spray, making it ideal for environments with strict oil requirements and preventing oil/gas contamination.
  2. High vacuum capability: Achieves ultimate vacuum up to 1 Pa, suitable for various vacuum needs.
  3. Quiet operation: Non-contact scroll design significantly reduces noise and vibration for quieter work environments.
  4. Energy-saving & high efficiency: Delivers high pumping rates with low power consumption for reduced energy costs.
  5. Frequent start/stop: Can start and stop frequently between atmospheric and vacuum states, adapting to dynamic operational requirements.
  6. Compact design: Small, easy-to-install pump body saves valuable workspace.
