Technical Specifications

The patented Flexible Diaphragm Coupling from KOP-FLEx couplings transmits torque from the driving shaft via a rigid hub, then through a flexible diaphragm to a spacer. The diaphragm deforms while transmitting this torque to accommodate misalignment. The spacer in turn drives matching components attached to the driven equipment. Outstanding design features include:

  • Field-replaceable stockable diaphragms
  • Specially-contoured one-piece diaphragm design
  • Patented diaphragm shape
  • Piloted fits
  • Diaphragms are 15.5 PH shot-peened stainless steel
  • Inherently low windage design
  • Conforms to API 671 specifications
