Direct Drive Oil-Sealed Rotary Vacuum Pumps G-20DA
Two-stage / with cord, and switch

 
Features

Our company's Direct-drive Oil Sealed Rotary Vacuum Pump is the Sliding Vane "Gaede type". It employs oil in the vacuum pump to lubricate the rotary part and to allow sealing effect upon vacuum formation, thus obtaining a high degree of stable vacuum and high reliability. This small direct-drive motor excels over belt-driven types both in quickness of starting and pumping.

Caution
1. Ensure the proper oil level and oil condition are maintained at all times.
2. Before stopping a pump it should be vented to atmosphere to prevent the back-streaming of oil. (Contact your local sales representative for applications assistance.)
3. When operating a pump for long time above 0.1MPa, it is possible that oil mist be exhausted from the exhaust port. Installation of Oil mist trap (OMT Series) will eliminate this potential source of contamination.
4. Oil-sealed rotary pump is not recommended for continuous operation near atmospheric pressure.
