Laboratory vacuum pump MD 1

diaphragmmulti-stagedry

Overview

• Oil-free, contamination-free pumping and evacuation
• High pumping speed even close to ultimate vacuum
• Ultimate vacuum 1.5 mbar (≈1.1 torr)
• Very low noise and vibration
• Long diaphragm lifetime; maintenance-free drive

Product summary
The MD 1 diaphragm pump is a compact, oil-free pump for evacuation and pumping of non-corrosive gases. Its three-stage design with precisely guided flat diaphragms provides superior pumping speed close to the ultimate vacuum compared with two-stage designs. Flow-path materials (aluminum and selected plastics), PTFE/FKM diaphragms and FKM valves make the pump suitable for a wide range of non-aggressive gas applications. The MD 1 is ultra-low vibration, has a documented long diaphragm life and is delivered ready for immediate use.
