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

 
Features
ULVAC KIKO's Direct-Drive Oil-Sealed Rotary Vacuum Pumps are the sliding vane "Gaede Type". Oil is used to lubricate the rotary mechanism and to seal the vacuum pumping chamber, producing excellent vacuum stability and reliability. Small direct-drive pumps feature faster start-up and quicker pump down compared to belt-driven pumps. In addition, ULVAC KIKO 's G-Series Oil-Sealed Rotary Vacuum Pumps are cost-effective and operate quietly.

G-Series pumps are available in single and dual stage versions with pumping speeds ranging from 5 L/min. to 100 L/min..

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.
