The Samiflex® spacer coupling is designed for use in motor–pump assemblies.
It can be configured with a standard A or CS hub, a spacer, a flange hub, a ring, and an elastic insert. The spacer allows a free distance between shafts, enabling the pump rotor to be removed for maintenance without the need to move any components of the assembly.

The spacers are manufactured in different lengths according to the standard ISO specifications for centrifugal pumps.
