Coupling description
RIGIFLEX®-HP is available as a compact type C with a high power density and type L for larger shaft diameters.
Thanks to variable lengths, the spacer mounted by the manufacturer allows for an individual adaptation to each of the
drive trains concerned. Both types are characterized by low ventilation and benefi t from an easy assembly. Apart
from that they are in accordance with the standards API 671 of the American Petroleum Institute which means that
they are permissible, among others, for an international application in petro-chemistry.
