Abstract: 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.

Abstract: A portable fire extinguishing nozzle arrangement has a nozzle head provided with fire extinguishing nozzles that may be connected to a supply pipe. A plurality of fire extinguishing nozzles are mutually spaced apart at the free front side of the nozzle head. When supplied with fire extinguishing fluid, each fire extinguishing nozzle generates a mist of fire extinguishing fluid. The fire extinguishing nozzles may be selectively supplied with fire extinguishing fluid individually and/or in groups through a valve combination.

Abstract: A fire extinguishing device activates fire extinguishing nozzle-heads in multiple locations in response to fire-induced activation of one of the fire extinguishing nozzle-heads. The fire extinguishing nozzle-heads are connected to a supply pipe which conducts a fire extinguishing fluid from a pressure generator. Each nozzle-head includes at least one fire extinguishing nozzle and a fire detection contrivance, which, in the event of a fire, triggers the issue of the extinguishing fluid from the activated fire extinguishing nozzle. Each of the fire extinguishing nozzles-heads further includes at least two connecting channels providing communication between the fire extinguishing nozzles and a supply pipe. Both connecting channels are normally closed by respective shut-off devices while the extinguishing nozzle-heads are in a quiescent state.
