Application examples:
Suitable for high pump capacities.
With the TMR G3 series, Lutz presents a reliable magnetic coupling pump with a patented magnetic axial thrust compensation that easily handles even critical application conditions.

Features:

  • Drive via magnet coupling with patented magnetic axial thrust compensation
  • Motor and pump mechanically separated
  • Performance range max. 48 m³/h and 42 m delivery head
  • Suitable for densities up to 1.8 kg/dm3 and viscosities up to 150 mPas
  • Housing material PP (GF) or ECTFE /CF)
  • Connections with BSP/NPT thread or ISO/ANSI flange
  • Version GX approved according to ATEX Directive 2014/34/EU, Category 2

Benefits:

  • No dynamic shaft seal
  • Pump housing hermetically sealed
  • By “magnetic axial thrust compensation” the bearing system “R” is suitable for dry running
  • Also for liquids with a high specific density
  • Variable connection options
  • Metallic protection plate protects the pump housing against mechanical damage
