Diaphragm Membrane Coupling with SS Discs in Factory Assembled Disc Packs

Cartridge Design Membrane Unit Construction
The M Series coupling range is particularly suited for electric motor or turbine drives in the oil and gas industry. Torque is transmitted through two sets of pre-assembled membrane units, separated by a spacer element.

The coupling provides a good level of angular, lateral and axial misalignment, whilst maintaining a high level of balance integrity. In the unlikely event of membrane failure, due to a torque overload, the coupling will disconnect the drive, thus protecting the associated shafts. Standard options for spark resistance available.

Design Features
Product Description

  • Easy to fit cartridge and membrane units
  • Ideally suited for eletric motors and turbine drives in critical process industry, marine and power generation.
  • Meets API 610, can be supplied to meet API 671.
  • Intrinsic balance meets AGMA class 9.

Design Features

  • High misalignment capability.
  • Stainless steel flexible membranes for maximum life.
  • Excellent power-to-weight ratio.
  • Cartridge membrane design reduces stock inventory.
  • The replaceable membrane units can be fitted to any length spacer to maximise the use of inventory held.
  • Low imposed forces on machinery leading to a reduced machinery vibration and maximised bearing life.
  • A bearing is fitted between the guard rings in the very unlikely event of membrane failure the spacer will freely rotate giving no flow indication on the pump permitting the operators to shut down the machinery safely.
  • Anti-fly pretention of the spacer in the unlikely event of membrane failure.
  • Standard API puller holds incorporated into hubs.
