N 920 diaphragm vacuum pumps
A vacuum pump's pumping capacity at atmospheric pressure is a commonly cited measure of performance.
But in practice, suction capacity at low pressures has proven to be even more relevant.
This is where the diaphragm vacuum pumps of the N 920 series from KNF Neuberger set new standards.
Thanks to a patented diaphragm stabilisation system, they are able to pump considerably higher volumes under vacuum than conventional diaphragm pumps - and do it with greater long-term vacuum stability.
Their performance makes these units ideal for service as roughing pumps on turbo molecular pumps, for analytical engineering, and general laboratory use.
The new model N 920.29.18 now has a knob-type potentiometer that permits adjustment of the pumping capacities directly at the pump.
As a result, the pump is ideally suited for individual, flexible deployment in the laboratory.
Its compact design saves space on a lab bench.
The suction capacity is up to 1.3 cubic metres /hour and the ultimate pressure is <1.5 mbar absolute.
All vacuum pumps of the N 920 series transfer analytically uncontaminated, work quietly and with low vibrations.
They are driven by cool-running motors that work with high efficiency and low power consumption and are able to automatically adapt to the electrical power supply.
As a result, these pumps can operate on voltages that range from 90 to 264 V as well as with 50 or 60 Hz frequency.
