I am new to Pump engineering forum. This refers to the correct sizing of a motor drive for a pump to estimate the input electrical power (kVA) requirement. I understand that the following equation gives the required HP for a pump to give out a given discharge at a given head.) If it is a mechanical coupling, you can usually ignore the coupling loss. In the rare instance that it is an eddy current or a hydraulic coupling, I would allow 5% of pump power for preliminary sizing purposes only. Do not select motor size on duty point; if unsure add 20% and go for the next standard motor size up.
