Abstract
A metering pump unit with a metering chamber (), a positive-displacement body that adjoins the latter and 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 () at least in a specific operating state in such a way that a stroke, in particular a pressure stroke, of the positive-displacement body is started at a first, lower stroke rate, and the stroke rate is increased to a second, elevated stroke rate as the pressure stroke () continues. A method is provided for controlling the positive-displacement drive () of such a metering pump unit.
