ABSTRACT:
A cream whipping machine has an electric motor (1), a vane pump (3,9) and a whipping barrel (26) fitted closely together in axial alignment. Air and cream are sucked in to the pump chamber (14) via an intake assembly (16). A pump rotor (3) is fixed to a motor shaft (2) and a pump casing (9) together with the whipping barrel (26) and intake assembly (16), may be withdrawn from the rotor by undoing bolts (11). A space (13) to the motor side of a main pump seal (8) is vented to atmosphere through an opening (12) so that if the seal fails the liquid product is not forced into the motor.
