    what is Pumps process Minimum Flow?

    thanks for your suggestion but as per my knowledge pumps minimum flow should not be the more than the process minimum flow, and for shut off API 610 say for parallel operation minimum shut off head should not be less than 10 %,i want to know why 10 % shut off head is required.
