For example, the normal and minimum flow rates of pumps can be calculated in the process of design and research. When selecting digital metering pump, if there is no maximum flow value data, the normal flow is considered. 1.1 times of normal flow can be considered as the maximum flow data for reference selection.
2. The lift required by the equipment system is another important performance data for selecting the pump.
generally speaking, the type is selected with reference to the lift enlarged by 5% or 1%.
