Two-Stage Transformer Vacuum Pump with Roots Pump


Two-Stage Transformer Vacuum Pump with Roots Pump vacuum is mainly used for vacuum drying and vacuum oiling of 220KV, 500KV, ±800KV, 1000KV, and other high-voltage power transformers. The powerful vacuum pump makes the working vacuum degree reach 10Pa, and the vacuum degree is limited to 1Pa.

Product Features:

  1. A large pumping rate is available over a wide pressure range. It acts as an “accelerator” on the foreline pump for raising its high pumping speed and ultimate vacuum.
  2. ZJ series roots vacuum pump running parts without friction, no lubrication, no oil in the pump cavity, and you can get a clean vacuum.
  3. The vertical flow of gas in the pump chamber is conducive to the elimination of dust and condensate in the pumped gas.
  4. The rotor, with complete symmetry and precise dynamic balance, runs smoothly and reliably.
  5. Compact structure, designed with vertical and horizontal two exhaust ports, easy to install.
  6. The mechanical friction loss is small, so the driving power is small.
  7. Easy to maintain and repair, low cost, and high life.
  8. The vibration and noise are small.
  9. Can extract condensable gas.
  10. Eliminate oil leakage and emulsification – the application of imported oil seal shaft extension seal and composite seal structure design.
  11. Safe and reliable, it is equipped with an overflow valve to automatically protect the function.

Applications of Two-Stage Transformer Vacuum Pump with Roots Pump:

  1. Two-Stage Transformer Vacuum Pump with Roots Pump is mainly used for vacuum drying and vacuum oil-injecting for high voltage electrical transformer as 220KV, 500KV, ±800KV, 1000KV.
  2. Strong vacuum pumps make working vacuum degree to 10 Pa and limit vacuum degree to 1 Pa.
  3. In addition to this, you can also choose from more types of vacuum pumping systems.
