Abstract (en)
[origin: WO9421924A1] A pump including a sealed chamber (10) which can suck in a product feed through a first inlet (16) by means of an air pump (32) forming a partial air vacuum therein via a port (19). The product is received in an inner vessel (20) supported on a weight sensor (30) which outputs an electrical signal representative of the product weight. The signal is fed to an electronic air pump control unit (50). Once the product has reached the desired weight, it is discharged by the air pump pressurising said chamber, the product exiting through a vertical outlet (18) with its lower end at the bottom of the vessel.
