Powerflex High Performance couplings have an innovative design that bring high reliability for transmissions in
They are projected to comply with most requirements of the API 671 standard, with respect to assembly.
Hubs, guard rings and spacers are manufactured with high alloy steels, while flexible elements are made with
high grade stainless steel and the fixture parts undergo rigourous quality control.
As a result of controlled assembly, interference pilot guide and screws with controlled tolerance insure the
balancing integrity even after many assemblies.
The flexible coupling must handle two functions: (1) Transmit drive torque to the driven machine and (2)
accommodate misalignment of the axles.
High Performance Powerflex couplings are specifically designed to handle these tasks required in critical
actions such as: compressors, feeding pumps, injection pumps, generators, gas and vapor turbines and
API 671 applications.
- More flexibility.
- Low reaction force.
- Uniform stress distribution.
- Reduced weight and inertia.
- Compact assembly.
- Hubs allow high bore capacity.
- Use of materials with high
- Tolerances and balancing
that comply with the API 671
