Specially for pump drives

RIGIFLEX-N® models are used wherever reliable and maintenance-free torque transmission needs to be combined with shaft misalignment handling capability.

The RIGIFLEX-N®, developed specifically for pump drives, complies with the regulations of API 610 and can optionally be supplied in API 671-compliant form (API = American Petroleum Institute).

This torsionally rigid coupling is particularly well suited for use in refineries.
