A high-speed and high-torque coupling
Voith diaphragm couplings combine unique know-how and decades of experience, resulting in their reliable and exceptional performance. As high-performance units, they convert high torque at high speed despite their low weight.
Technical features
Compensating for axial, radial, and angular misalignment of two coupled shafts, our diaphragm couplings are manufactured for torques of up to 1,500,000 Nm and speeds of up to 80,000 rpm. These high-speed and high-performance couplings fulfill the requirements of API 671 as well as ISO 10441 and are approved for Zone 1 and Zone 2, following ATEX standards. Furthermore, the standard couplings are designed for angular misalignment up to 0.25°, and bespoke couplings are available on request for angular misalignment of up to 0.5°.
