Key Advantages
  • High level of gas tightness, from 5 × 10-5 to 6 × 10-6 mbar × l/s
  • The pump copes well with aggressive/corrosive media
  • The pump can start against the entire pressure and vacuum range 
  • Stable transfer rate at all pressure levels throughout the process
  • The permissible ambient and media temperatures can be extended to 60 °C / 140 °F with water cooling for non-Ex versions
  • The affixed base rails and shock mounts effectively minimize noise and vibration
  • The series fulfills the criteria for completed machinery according to directive 2006/42/EC, thus comes with the CE mark
Possible Areas of Use
