Magnetic stirrer coupling (G-MRK), glass+PTFE

Magnetic stirrer coupling (G-MRK)
  • Perfect combination of drive shaft with ball bearings, rotor and lower bearing made of PTFE/PEEK and a conductor made of borosilicate glass.
  • Requires little space due to compact construction.
  • No leakage or memory effects due to non-porous, welded rotor.
  • This rotor holds the stirrer shaft by means of three stud screws which are fixed in the counterbores of the stirrer shaft.
  • This provides optimum power transmission and a safe fixing.
  • The 6 mm square can be fixed into the stirrer coupling or into the agitator.
Product advantages:
  • Powerful transmission for ground joint size 19/26: 15 Ncm / for ground joint size 29/32 and 45/40: 50 Ncm
  • No grease required
  • All products which are exposed to the medium do not contain any metals
  • High speed of up to max. 1.500 rpm
  • High working temperatures up to +250°C are possible
  • Excellent chemical resistance
  • Safe to run dry
