M Series Multiple Membrane Straight Diaphragm Coupling with Stainless Steel Discs in Pre-assembled Single Diaphragm Packs
With John Crane’s Metastream® MHS Series coupling range, the torque is transmitted through pre-assembled packs with a built-in safety bush to help protect your equipment. The coupling meets API 610 and provides a strong level of angular, lateral and axial misalignment, while maintaining a high level of balance integrity. In the unlikely event of membrane (disc) failure due to a torque overload or excessive misalignment, the coupling will disconnect the drive and run on the safety bush, permitting the driven machine to safely come to rest without further damage to the equipment. This series is available with a single pre-assembled pack (MHSO) for short shaft separations on three bearing applications and with two pre-assembled packs (MHSS) with a high strength spacer piece between for longer shaft separations on four bearing applications. The pre-assembled pack(s) are available in numerous material combinations, including a spark resistant option.
