Overview- Contamination-free pumping and evacuation
- High performance even close to the ultimate vacuum
- Whisper-quiet operation
- Very low vibration
- Long diaphragm life and maintenance-free drive
Product descriptionFour-stage diaphragm pump designed for continuous, oil-free pumping of gases down to fractional millibar ultimate vacuums. All wetted parts are made of aluminum, stainless steel and selected plastics suitable for a wide range of non-corrosive applications. The pump combines high pumping speed with an excellent ultimate vacuum (down to 0.5 mbar). Highly flexible, fabric-reinforced double diaphragms made of FKM extend service life. The 8-head NT design provides quiet operation and smooth, easy-to-clean external surfaces.
