The dosing pump to force a concentrated cleaning agent in water, through beverage dispensing equipment, has a rotating drive disk (2) in the hollow space within a housing (1). It carries three sprung paddles (4), inserted into radial drillings at intervals of 120 deg . The hollow interior is formed by two half-cylinders (7,8), where the lower section (7) matches the radius of the drive disk (2) and the upper section (8) has a larger radius. As the disk (2) rotates, the paddles (4) slide against the walls of both half-cylinders (7,8). The hollow zone defined by the upper half-cylinder (8) has two fluid feed lines (10,11) to feed and extract the cleaning agent. A piston within a cylinder moves up and down to apply suction to the concentrated cleaning agent, with a connection for the cleaning agent feed line at the cylinder housing the piston.
