Product Description
Mobile Type High Vacuum Transformer Vacuum Pump Units

  In case single vacuum pump is not suited for a certain process due to pumping speed or 
ultimate vacuum. DYK Series vacuum pumps unit consist of roots pump as booster and 
rotary vane pump as backing pump, the exhaust from the roots pump is connected to the 
suction side of the backing pump thereby giving advantage of high pumping speed at 
higher vacuum. The pumps unit also equips air cooling system, cooling water system, 
vacuum valves, ventilation valves, compensator, vacuum meter etc, and highly efficient, 
reliable and consume less power. It also can be designed and mounted on base frames 
ready for use, or trailer are offered to suit user's requirements. DYK unit is wildly applied 
in vacuum metallurgy, vacuum drying, welding, chemical, laboratory, power station and 
other industrial vacuuming, especially for vacuum transformers and other electrical 
equipment operation.

1.Roots pump automatically runs by the start of backing pump with electrical-contact 
   vacuum meter.
2.The powerful rotary vane backing pumps generate the necessary backing pressure 
   so that the diffusion pump can always attain its full pumping speed and an ultimate vacuum
3.The pumping unit has vacuum valve at the inlet and a rough vacuum line (bypass). 
   This makes it particularly efficient for rapid evacuation cycles.
4.The high vacuum pump unit offer outstanding energy savings, high efficient, reliable  
   and low power consumption
