A metering system for metering a liquid has an electric motor () for setting a desired feed rate, by modifying the rotation speed of the electric motor. It furthermore has an eccentric drive (), drivable by said electric motor (), for a pump () that has two delivery directions. It also has a pump ring () made of an elastomeric material and a stationary ring () which is arranged relative to the pump ring () and to the eccentric drive () in such a way that a pump chamber (), extending in a circumferential direction, is formed between the stationary ring () and pump ring (). The chamber changes shape upon rotation of the electric motor () in order to deliver a liquid to be metered through the pump chamber (). A stationary seal () is provided in the pump chamber (), between two fluid ports.
