The vacuum pump N 920 from KNF Neuberger pumps down very efficiently, with great process reliability. This is made possible by an innovative diaphragm stabilization system. lt ensures high suction speed, especially at low absolute pressures. Additionally, it provides a high degree of long-term vacuum stability. Thanks to the diaphragm technology, this pump transfers and pumps down analytically uncontaminated. lt is available in both a portable version and an OEM version for mounting. The suction speed of the diaphragm vacuum pump N 920 is up to 1.3 m³/h at atmospheric pressure, the ultimate vacuum is smaller than 1.5 mbar abs.
