Robust and durable, with high pressure and high gas tightness, the N 630 offers unparalleled capabilities. The pump series is already being expanded. Non-explosion-proof versions will now also be available for a wide range of tasks in the areas of environmental measurement technology and process manufacturing as well as in the chemical industry.

Features & Benefits

These are the main advantages of the N 630 gas pump series:

  • High chemical resistance
  • Durable even with difficult operating conditions
  • High level of gas tightness
  • Ambient temperatures of up to 60 °C possible with water cooling
  • The pump can start against the entire pressure and vacuum range 
  • Stable transfer rate at all pressure levels throughout process
  • Quiet operation with minimal vibration 
  • High operating pressure of max. 12 bar rel. (N 630.15 version only) 

The Right Fit for Your Need

The N 630 is available in four variants: either one-headed or two-headed and connected in series or parallel, as a vacuum pump or compressor. All models come with an optimized, PTFE-coated diaphragm, which is the primary reason for the pump’s robustness and long service life.
