A multiple membrane pump for food liquids, comprising at least one duct for the compensated intake of the liquid, which is closed on itself in a loop and is provided with at least one intake port, at least one duct for the compensated delivery of the liquid, which is closed on itself in a loop and is provided with at least one delivery port, at least four branches, which provide a unidirectional connection between the intake duct and the delivery duct and are associated respectively with four liquid pumping membranes, a gearmotor assembly, which is associated with a crank system for actuating the membranes and is adapted to convert the rotary motion of an output shaft of the gearmotor assembly into a reciprocating motion, adjusted with an appropriate timing between two mutually opposite intake and delivery stroke limit positions, of each of the actuation axes of the membranes.
