MD 4C NT diaphragm vacuum pump
Three-stage, high-power diaphragm vacuum pump with extremely high delivery rate almost up to the end vacuum. Often used as a replacement for rotary pumps due to reaching a very low end vacuum. Ideal for continuous, oil-free evacuation and conveying of gases and vapours to meet eh high vacuum requirements of physics and analytical applications
- NT series: particularly quiet, low-vibration operation, high gas-tightness and improved performance characteristics
- Extremely high diaphragm service life
For aggressive and corrosive gases and vapours.Application: vacuum generation for rotary evaporators/drying ovens, for pumping out large quantities of vapour from drying ovens/gel dryers and many other laboratory vacuum applications without solvent recovery.
- Excellent chemical resistance
- High vapour and condensate resistance thanks to integrated gas ballast valve - also suitable for high boilers thanks to the very high end vacuum (even with open gas ballast valve)
