Abstract
A metering pump system for supplying an aqueous chemical to a destination stock includes a first metering pump and a second metering pump connected to a common suction line and a common discharge line and operable to supply a desired chemical feed rate, an electronic flowrate sensor in communication with one of the common suction line and the common discharge line to measure an actual flowrate of the metering pump system, a controller in communication with the first metering pump, the second metering pump, and the electronic flowrate sensor, a control loop in use implemented by the controller to operate one or more of the first metering pump and the second metering pump to correct a deviation between the desired chemical feed rate and the actual flowrate measured by the electronic flowrate sensor.
