A metering pump (1) for feeding grout formed of at least two components. The metering pump (1) comprises a feed cylinder (2) within which a feed piston (2a) is positioned. Two or more metering cylinders (3, 4) with respective metering pistons (3a, 4a) therewithin are connected to the feed cylinder. The metering cylinders (3, 4) comprise metering spaces (V1, V2) into which liquid is introduced for metering grout. By displacing the feed cylinder, liquid contained in the spaces (V1, V2) is passed into the storage spaces of the different components, so that each grout component is forced into the drill hole in an amount equal to the amount of liquid removed from the spaces (V1, V2) by the movement of the pistons (2a to 4a). |
