Double Stage Vacuum Pumping for Transformer

Double stage vacuum pumping for transformers produced by YUNENG is fast in start-up and pumping, and thus it is especially suitable for the vacuolization of transformers. Besides, it can also be used for vacuumize in vacuum metallurgy, welding, chemistry, pharmacy, coating, and electronic industries.

What is Double Stage Vacuum Pumping for Transformer?

In most cases, a 2 stage pump will go down below 1 micron .001mm mercury vacuum. A single-stage pump is generally specified out at less than 15 microns .015mm mercury vacuum. 2 stage pumps are more expensive than a 1 stage pump because they have a high vacuum stage, what we refer to as an exhausting stage.

Advantages of Vacuum Pumping for Power Transformer:

  1. Double Stage Vacuum Pump System for power transformer oil filtration machine has GIS connection.
  2. It features digital vacuum degree management, anti-absorption, fast start, strong vacuum pumping capacity, stable performance, and easy operation.
  3. There is a combination of axial fan and condenser to deal with moisture and gas from the vacuum pump and roots pump. It can prolong the time to change vacuum oil while meeting emission standards.
