ABSTRACT:
A vane pump delivers pasty materials, particularly sausage stuffing, for the purpose of filling doses of the stuffing into sausage cases. The flow of material into the pump chamber generally takes place by a stuffing device in the hopper and by the action of the vacuum to which the vane pump is exposed. The degree of filling and therefore the dosing accuracy is improved by providing a curved portion in the transition area between the inner wall of the cylindrical part of the cup-shaped pump casing and the base part of the latter receiving the pump rotor mounting.
