High Voltage Transformers Vacuum Pump Unit Stationary Or Movable Type



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) The forward pump adopts the original world's leading vacuum pump imported from Europe, and customers can choose the imported Roots pump or homemade ones according to their purchasing power.The pump can attain high working vacuity at a vey fast pumping speed.

2) Roots pump automatically runs by the start of backing pump with electrical-contact vacuum meter.

3) 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

4) The pumping unit has vacuum valve at the inlet and a rough vacuum line (bypass). This makes it particularly efficient for rapid evacuation cycles.

5) The high vacuum pump unit offer outstanding energy savings, high efficient, reliable and low power consumption

6) Equipped with Pipeline filter so as to keep large impurities out of the system, not damaging the vacuum pump.

7) Simple structure and convenient in operation
