GKF – GROOVED FLEXIBLE COUPLING – TDS_EN.pdf

Description

 Flexible couplings are designed to allow axial displacement, rotation and some angular movement. The coupling can accommodate angular misalignments up to a few degrees. It can also accommodate parallel misalignment and/or thermal deformation when using two couplings with an intermediate pipe.
