Improving pump reliability through its secondary components

摘要

Pumps are critical items of rotating equipment in the process industries. Their failure can have huge consequences in terms of cost and safety. Pump reliability is, in turn, dependent on performance of its principal secondary components such as seals, couplings and bearings. This paper looks at the influence of those components on overall pump reliability, sets targets for life times and looks at ways of improving the performance of those secondary components. The paper concludes with case histories, which show real improvements in practice.
