        how to determine the selection of the pump flow
        Time:2011-4-14
        The flow is the production of process equipment, requiring pumping of medium quality.
        Usually in the data table given the normal, minimum and maximum flow. When selecting a pump generally require the pump rated flow of not less than the maximum flow of the device. For only the normal flow given the circumstances require the pump rated flow of normal flow of 1.1 to 1.15 times.
        For the viscosity> 20mm 2 / s or the media containing solid particles, need to be converted into the time of delivery of water flow, and then determine the pumps rated flow.
