| 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
is dependent on the type and style of flexible coupling applied. Left unchecked, coupling
misalignment has a significant impact on the overall life of the mechanical seals and
bearings of the pump. |
