Product details
Chemistry-design diaphragm pumps provide a continuous, oil-free solution for pumping corrosive gases and vapors. The single-stage construction offers the advantageous combination of high pumping speed and an ultimate vacuum down to 70 mbar. All major parts in contact with the pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms improve reliability and extend operating life. The NT series delivers improved performance data and superior vapor tolerance. Items supplied: pump completely mounted, ready for use, with manual.
