Screw Type Dry Vacuum Pump is SCREW DIRECT COOLING TYPE
- No Thermal expansion of screw rotors
- No damage TEFLON coating
- No balance pocket
- No leak by the steam plushing
- Screw rotors patent
Low Ultimate Pressure
The single stage, slow rotational speed of 3600RPM at 60HZ is able to operate
from atmospheric pressure to its ultimate pressure level of 1 X 10-2 Torr and continous
operation is possible at any pressure level.
Unique Screw Rotor Design
Cooling water path through the inside of scrow rotors.
Low Temperature of screw rotor
Low Temperature of screw rotor enable Long-Life-Coating, and is suitable for chemical gas process.
Oil & Water free operation
No oil or water is needed inside the vacuum pump-no disposal cost, easy product recovery, environmentally friendely.
Mechanial seal design on the shaft prevents water or oil contamination and insures clean oil & water free operation.
Corrosion resistant design
As special anti-corrosion coating is applied to all parts that in contact with gas.
Durable mechanical design
No metal-to metal contact between rotors themselves or the casing, low rotational speed insures long pump life, low vibration, low noise level and minimum wear.
Severe duty operation
The DONGBANG has an inner purging system with nitrogen, cooled process gas or air. There is a flow control device for dilution of toxic, corrosive, and condensable process gases.
