Oil-sealed Rotary Vacuum Pumps
P222
Oil-sealed Rotary Piston Vacuum Pumps
Features
- Stable and continuous operation at high pressures (low vacuum zones)
- Withstanding operation characterized by severe repetition
- Robust exhaust valve
- Sight glass for observing oil circulation
- Oil gauge for observing oil level
- Efficient oil separator
- Easy to make an inspection and maintain the exhaust valve case
- Easy cleaning oil tank because of a large cleanout
