  • The SC Type coupling consists of two flanges, a sleeve and two shaft hubs
Quick Coupling Removal
  • The center drop out section consists of two flanges and the flexible sleeve
  • The flange is bolted to the shaft hub with four hex head cap screws
  • The center drop out section can be removed by removing the hex head cap screws
  • Flats on each hub provides a convenient grip for a wrench in order to facilitate loosening of the screws and, if desired, turning of the pump/motor shafts
  • Once the hub is removed from the pump shaft, maintenance on the pump can be done without disturbing equipment alignment
