The Least Whole Life Costs of Progressive Cavity Pumps in the Coating Kitchen

The principles of designing a progressive cavity pump that will give the lowest total cost of ownership. the “Least Whole Life Cost”, are described and discussed. A balance between initial capital cost and subsequent operating costs will result in the most economical solution.The factors influencing the maintenance and operating costs over the typically 20-year life of the pump include power consumption and component wear. The mechanisms of wear and the conclusions drawn from 10 years of a scientific research program are summarised.The Mono Pump that offers the lowest Least Whole Life Cost is described, and actual site experience is quoted to illustrate the successful application of the theory.
