In nearly all industrial plants, and especially in the process industry, pumping systems require a considerable share of the total energy consumption. Therefore, saving energy in an economically feasible way is a constant concern for plant managers and engineers alike. Experience shows that in existing plants pump systems are often not optimized, in particular where energy consumption is concerned, utilizing ‘wrongly’ sized (mostly oversized) pumps. This is often the result of adding safety margins.
What is your experience of oversized pumps causing undue energy consumption and what solutions would you suggest?
