API High-Performance Disc Couplings
High-performance metallic coupling solutions for critical rotating equipment.
Supplied as the original brand or as an engineered equivalent, depending on availability and the required delivery time.
What is an API coupling?
API couplings are high-performance metallic disc or diaphragm couplings designed to the requirements of API 610 (pumps) or API 671 (special-purpose couplings for compressors and turbines) used in the oil, gas and petrochemical industries. They are balanced for high speeds, need no lubrication and are engineered for long, reliable operation of critical rotating equipment.
For critical pump, compressor and turbomachinery duties where API-oriented engineering, documentation and verification may be required.
