Improve API and ASME centrifugal pumps reliability with permanent magnet shaft couplings

Alkhowaiter, A., Machinery Consultant

Many factors reduce centrifugal pump reliability. Internal factors include pump design aspects, manufacturing deficiencies, maintenance deficiencies such as lubrication, or process related problems. Other factors are external: the shaft coupling is one of the external elements causing reduced mean-time between failures (MTBF) and pump life through misalignment, friction and unbalance forces.
