ABSTRACT

The primary objective of life cycle costing is to evaluate and/or optimize product life cost while satisfying specified performance, safety, reliability, accessibility maintainability, and other requirements. Centrifugal pumps rank first in failure incidents and maintenance costs. Carefully matching the pump with the system can ensure the lowest energy and maintenance costs, and yield maximum equipment life. The care and effectiveness in executing these installation activities will have a great impact on subsequent reliability, maintenance and down time costs, during the life cycle of the pump. Energy and maintenance costs during the life of a pump system are usually more than 10 times its purchase price. Downtime can be minimized by optimized preventive maintenance programs, and programming major maintenance during annual shutdown or process changeover. The cost of unexpected downtime and lost production is a very significant item in total life cycle cost, and can rival the energy costs and replacement parts costs.
