RIGIFLEX® couplings are used on such applications which require a reliable and maintenance-free torque transmission with shaft displacement at the same time. The laminas are waisted lamina sets arranged in layers. They are connected to the hubs or flanges, respectively, in an absolutely backlash-free fit by means of positive-locking set screws.

Laminae

RIGIFLEX® laminae are waisted laminae sets arranged in layers. They are connected to the hubs or flanges, respectively, in an absolutely backlash-free fit by means of positive-locking set screws. The number of the layers of individual laminae allows to vary torques, displacement figures and stiffness for special designs.

Securing the spacer

Since our main idea with the development of RIGIFLEX® couplings was to comply with the standards of API 610 and API 671, the spacer is secured by a safety catch, too. In case that the laminae break the spacer remains within the coupling.

In general the removable part is supplied along with a laminae set preassembled by the manufacturer.

API 610 and API 671

The RIGIFLEX®-N corresponds to the specifications of the API 610 standard and can optionally be supplied in accordance with the API 671 standard. RIGIFLEX®-N is designed for average and heavy operating conditions in the pump industry. It is used on process pumps, boiler feed pumps, pipeline pumps of chemistry and petrochemistry. RIGIFLEX®-N is furthermore suitable for applications in the marine and compressor industry.
