Diaphragm
Couplings
High-performance flexible couplings for turbomachinery. Precision, durability, and ease of maintenance — available in high speed, low speed, and reduced moment configurations to API 671 standards.
Our Design
Flexible diaphragm couplings play a crucial role in torque transmission between shafts. This innovative design incorporates a metallic membrane securely affixed to the outer diameter of a drive flange, effectively channeling torque through the diaphragm to the inner diameter attachment point. The couplings excel in accommodating potential misalignments between connected shafts, ensuring optimal performance and reliability in diverse applications. Riverhawk can manufacture custom couplings to most OEM specifications, including low and high-speed designs, low-moment applications, and accessories including torque management devices.
Diaphragm Coupling Features
Weld Free Design
Modular, weld-free construction maximizes interchangeability and simplifies maintenance for heavy-duty applications.
Exceptional Balance Repeatability
Vibrations are minimized and equipment stays stable even under high loads and speeds — vital for tight-tolerance operation.
Contoured & Flexible
Accommodates angular, parallel, and axial misalignments between connected shafts, extending equipment lifespan and minimizing wear.
Easy Maintenance
Splined bolted connection allows repair or replacement of individual coupling components — no need to replace the entire assembly.
