Siemens presents ARPEX

At the Hannover Messe 2017, Siemens has presented the new N-ARPEX coupling with improved performance characteristics, which is an additional series in the range of torsionally rigid all-steel disc couplings. An optimized disc pack and a revised component design facilitate the transmission of higher torques and speeds as well as a higher bore capacity with standard hubs. All-steel couplings can be used in all applications that require reliable torque transmission in set-ups with shaft displacement.

The N-ARPEX all-steel coupling is suitable for driving pumps, fans, compressors, generator and turbine drives as well as paper and printing machine drives. The couplings are designed for a potentially explosive atmosphere in accordance with directive 2014/34/EU and fulfil the requirements of API610/ISO13709 and API671/ISO10441. N-ARPEX all-steel couplings are designed as standard for very low temperatures down to −50°C – which is up to 10° lower than previous versions in the ARPEX series.
