ArcOflex – diaphragm coupling

Diaphragm coupling with all-steel design

The diaphragm packs, which are made of rust-free stainless steel, allow for a high misalignment compensation capacity with low restoring forces and have been optimised using the finite element method (FEM). The comprehensive modular system allows a large number of potential variations - also for high-temperature ranges.

Highlights

• High misalignment compensation capacity
• High-strength, flexible stainless steel diaphragm packs
• Optimised via FEM – tapered diaphragm shape
• Can be used at high temperatures

Structure and function

The ArcOflex is a diaphragm coupling that is available in various designs:

• The single-cardan version compensates for axial and angular misalignments
• The double-cardan version additionally compensates for radial misalignments

The diaphragm pack made of rust-free stainless steel is provided as a complete module The connection at the port is performed using fit screws.

Features

• Backlash-free and torsionally rigid diaphragm coupling
• Single- and double-cardan design
• Wear-free and maintenance-free
• Temperature range: -35° to +150°C

Application area / utilisation

• Packaging machines
• Printing machines
• Pump drives
• Test bench construction
