Abstract

A Metering pump includes a displacement element (4), a drive system with an electric drive motor (12) driving the displacement element (4) and a control device (22) controlling the electric drive motor (12). The control device (22) is configured in such a manner that it detects the current position of the displacement element (4), detects the torque (M) of the electric drive motor (12) at several positions of the displacement element (4) and monitors the torque (M) in relation to the position of the displacement element (4), and a method for controlling such metering pump.
