Abstract
A pumping unit for the filling of containers in packaging machines, in particular of foodstuffs with fluid behavior with the presence of suspended particles, which allows reliable operation under aseptic conditions, and which is easily cleanable. The conical shutter of the pumping unit, selectively connecting the pumping piston to the product intake duct and to the product delivery duct, is movable backwards from its seat, so as to allow an easy and reliable cleaning of unit's body, with no danger of product deposit with consequent loss of aseptic conditions.
