Abstract
During the life of a plant, there often arises a need to change a pump’s rating to match a new plant operating condition or raise the mean time between repair (MTBR) of an unreliable pump. In these cases, rerating the pump instead of buying and installing a new one, if that is feasible, offers the plant owner worthwhile capital savings. Often the capital savings are sufficient to lower the payback period and raise the return on investment (ROI) to the point where the project becomes financially viable. The tutorial first addresses the circumstances when a rerate is warranted, then how to determine the new rating, and finally, by way of three examples, the general techniques for carrying out rerates.
