NOTICE:

Elastomeric couplings are specifically designed to accommodate angular shaft
misalignment, as well as parallel offset of the pump and motor shafts. However, the
amount of the offset and/or misalignment depends on the style of the applied flexible
coupling. If you do not correct this coupling misalignment, there is a significant impact on
the overall life of the mechanical seals and the bearings of the pump.
