Claim 14:
15. A dispenser head as claimed in claim 1, in which the pump comprises:
a rotor housed within a pump housing, configured such that the rotor can be driven to rotate within the pump housing operable to transport concentrate liquid from the pump inlet in fluid communication with a concentrate source, to the pump outlet in fluid communication with the dilution chamber; and
a seal member bearing against the rotor operable to prevent concentrate liquid from passing from the pump outlet to the pump inlet, and to expel concentrate liquid into the pump outlet, wherein the pump and the diluent duct are cooperatively configured such that pressure of diluent liquid within the diluent duct can be transmitted onto the rotor via the seal member.
