Portable Vacuum Pump Unit Fast Pumping Rate Double Stages Energy Saving



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.


Description of ZYK:

ZYK series vacuum pumping device is a new type of vacuuming equipment developed and produced by our company. It is widely used in the process of producing vacuum condition for various equipment. Its vacuum pressure can reach much lower than any other products in the same field.

It is widely used in the vacuuming process in the production, installation and maintenance of many electric power equipment, like electric power transformer, capacitor etc., and is also used in the technical process of industrial production, such as vacuum drying, vacuum distillation, vacuum wielding, vacuum coating etc.

It is not suitable for the vacuum process for air and gases containing too much powder, water and oxygen

as well as explosive, corrosive, poisonous and chemical substances.



◆ 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.

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

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

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

◆ Simple structure and convenient in operation,DYK adopt standard closed type structure suitable for outside operation

1. The former pump adopts the European original imported vacuum pump with the world leading level (natural air cooling). The Roots pump can choose the high quality domestically produced or imported products according to the purchasing power of the user. The pumping speed is fast and the working vacuum can be quickly obtained.
2. Equipped with pipe filter, can effectively prevent the larger particles of impurities into the system and cause damage to the vacuum pump.
3. The standard configuration of machine is closed type.The machine has beautiful appearance and convenient for outdoor operation
