Roots Pump Rotary Piston Industrial Vacuum Unit For Distillation Vacuum Suction

Roots Pump Rotary Piston Industrial Vacuum Unit For Distillation Vacuum Suction


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.


□ The working vacuum range is 7~133 Pa; the limiting vacuum can be up to 7 Pa. The vacuum unit is quick start and big pumping speed that can be used for vacuum smelting, jointing, pharmacy, electric vacuum device, especially for the vacuum evacuating of transformers.

□ DYK unit adopts roots vacuum pump as the main pump, rotary-vane vacuum pump as the fore pump. Between them connecting an electric-magnetic pressure differential valve which would be turned on when the fore pump is working. The inlet of DYK unite equips a micro thermocouple which can meter and control the vacuum of pumped container. All the valves are imported from German with good ability of airproof.

□ Circulating vacuum pump oil filter and circulating water cooling device are set up to ensure a reliable operation, keeping normal temperature of circulating water, without vacuum oil aging.

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

□ 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.

□ 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.

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


□ This system has a remarkable energy saving effect.

□ This system has very fast pumping speed during high vacuum pressure range.

□ This system can work well with filter device, if the gas contains small amount of water vapor or dust.

□ This system has the advantages of compact structure and convenient operation.
