Oil-free diaphragm pumps are nowadays the number one choice amongst the established vacuum pump technologies for generating vacuum in laboratories. However, even with known process parameters concerning ultimate vacuum, pumping speed and chemical resistance, the choice of suitable diaphragm pump is still often difficult. In this case it is important to take a detailed look at the technology within the pumps themselves and into the technical data which holds the key to the true performance and economic efficiency of the diaphragm pump.
Closer inspection of the New Technology behind the diaphragm pumps of the “NT” series from VACUUBRAND provide a very revealing insight. The unique “floating motor drive“ for example, is a patented new drive system which provides for extra quiet and low-vibration running of the pump and contributes to greater energy efficiency. New internal hose connections mean that the heat emission of the pump is used to reduce the condensation effect. Also, a patented new valve mounting system simplifies servicing and allows for independent changing of the diaphragms and valves. The culmination of these improvements has meant that VACUUBRAND has increased the benchmark vacuum performance yet again. So now with all “NT” products higher pumping speed and better ultimate vacuum can be achieved.
Add to this the proven VACUUBRAND technology for the gas contacting parts e.g. PTFE sandwich diaphragm, stability core system for the head cover and clamping disc and altogether it is easy to see how the “NT” diaphragm pumps provide an outstanding chemical resistance and superior vapour tolerance coupled with a market leading diaphragm life time.
To summarize, the “NT” product portfolio offers a broad range covering all of the diverse applications in the vacuum range from 0.3 to 70 mbar: for corrosive or non-corrosive gases and vapours, with fixed or frequency controlled pumping speed, as stand-alone diaphragm pumps or as complete, ready for use systems equipped with components for efficient solvent recovery and vacuum regulation.
