    GR Special Design Features
  • Antimony seals and bearings in the GRX provide longer life, especially on higher speed machines.
  • Sleeves are dual driven by two keys to give greater resistance to side load and eccentric motion.
  • External seal wear indicator for preventive maintenance.
  • All wear surfaces are treated for improved corrosion resistance.
  • Directly interchangeable with competitive designs.
  • Seal under compression design can better handle pressure surges and promotes longer life.
