This invention relates to a device for pumping high delivery volumes of a liquid, with at least two pumps each forming a single structural unit, which are jointly hooked up to a pressure line on the delivery side, and coupled to a single drive. The device according to the invention further develops the known device described in greater detail above in such a way as to provide an easily transported and space-saving device. This is achieved by virtue of the fact that at least one pump (4) is positioned in a plane spaced vertically apart from the plane in which the respective other pump (5, 6) is located.
