Vacuum Pumps
Liquid Ring Vacuum Pumps
Reliable, oil-free vacuum generation for process applications. Liquid ring technology is suitable for dry & humid gases, and can handle small amounts of entrained liquid during normal duty. Model range includes LEMD 27, LEMD 52, LEMD 92, LEMD 127, LEMD 162, LEMD 252, LEMD 327 and LEMD 427.
Overview
Liquid ring vacuum pumps are single-stage displacement pumps designed for stable evacuation of process gases. They are suitable for demanding operating conditions where reliability, low vibration, and tolerance to humidity are required.
Key Benefits
- Nearly isothermal compression (non-polluting operation)
- No lubrication inside the working chamber (oil-free)
- Suitable for gases and vapours
- Can handle small quantities of entrained liquid
- Low noise with minimal vibration
- Reliable operation with easy maintenance
Typical Use Cases
- Process vacuum duties (wet or humid gases)
- General industrial vacuum generation
- Applications requiring stable vacuum performance
- Systems where low vibration is important
