Abstract
A metering pump aggregate has a metering chamber (), adjoined by a positive-displacement body () that can be moved by a positive-displacement drive (), as well as a controller () for actuating the positive-displacement drive (). The controller () is designed to actuate the positive-displacement drive () in such a way, at least for specific setpoint conveyed flows to be generated by the metering pump, that a stroke of the positive-displacement body () begins with a first, elevated stroke rate (n), and is subsequently continued at a second, lower stroke rate (n). A method for controlling such a metering pump aggregate is also provided.
