Abstract
Often, an application or process calls for multiple pumps operating within a piping network. Pump load, such as flow rate or pressure, is shared between these multiple pumps. The present disclosure relates to effective means of distributing the pumping load in a manner that satisfies the process requirements while keeping the pumping machinery safe from functioning in damaging operating regions. It also discloses a method of operating pumps in an efficient or optimal fashion. An additional aspect is a method of using an open-loop response to deal with large transients threatening to force a pump into an operating region that might result in damage or destruction.
