VSX Double-Suction Split-Case Pump
Overview
Alignment-Friendly Coupling
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.
