Flexible element 1: polyurethane in the form of a Maltese cross.
Flange 2: cast iron with drive segments 3 supplied unbored (except633054 and 633055).
Variations : For assemblies with a ring or spacer, consult our technical manuals.
The MPP coupling is designed with the following features:
– Push fit assembly.
– Smooth, compact cylindrical shape, without protrusions.
– The flexible element operates under compression,
– Safe in use.
– Temperature range – 30°C to + 70°C in continuous operation.
Advantages:
– Reduced size.
– Easy to use.
Recommendation:
It is recommended that the coupling should not be subjected to axial tension which might cause the flexible element to slip off the drive segments on the flanges.
