The invention relates to a double diaphragm pump having flexible diaphragms disposed in displacement spaces and connected and mechanically coupled to piston rods, the displacement spaces being communicated via check valves to a suction manifold on the one hand and to a pressure manifold on the other hand, wherein each diaphragm is connected to a piston rod, which piston rods extend coaxially and are mounted on opposite sides to a guide frame having at least one lineal guide for a guide block which rotatably mounts a crank pin of a crankshaft.

A double diaphragm pump having flexible diaphragms disposed in displacement spaces and connected and mechanically coupled to piston rods, the displacement spaces being communicated via check valves to a suction manifold on the one hand and to a pressure manifold on the other hand, wherein each diaphragm (26,28) is connected to a piston rod (66,68), which piston rods extend coaxially and are mounted on opposite sides to a guide frame (64) having at least one lineal guide (84,86) for a guide block (88) which rotatably mounts a crank pin (102) of a crankshaft (94), the lineal guide comprising round rods (84, 86) for engagement with corresponding guide bores (90, 92) of the guide block.
