Abstract (en)

A multiple membrane pump for food liquids and the like, comprising at least one duct (6) for the compensated intake of the liquid, which is closed on itself in a loop and is provided with at least one intake port (7), at least one duct (8) for the compensated delivery of the liquid, which is closed on itself in a loop and is provided with at least one delivery port (9), at least four branches (10, 11, 12, 13), which provide a unidirectional connection between the intake duct (6) and the delivery duct (8) and are associated respectively with four liquid pumping membranes (14, 15, 16, 17), a gearmotor assembly (18), which is associated with a crank system (19) for actuating the membranes (14, 15, 16, 17) and is adapted to convert the rotary motion of an output shaft (20) of the gearmotor assembly (18) 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 (21, 22, 23, 24) of the membranes (14, 15, 16, 17).
