Abstract
An apparatus for selectively dispensing liquids, such as paint colorants. The apparatus comprises container assemblies with a container and a pump. A pump conduit connects the pump to a valve assembly. A recirculation conduit connects the container to the valve assembly bypassing the pump. The valve assembly is configured to be switched between a dispensing position and a recirculation position closing off the dispense conduit. Method of preventing segregation of a multiphase liquid in a pump conduit between a container and a dispense conduit. A valve assembly between the pump conduit and the dispense conduit closes off the dispense conduit while it opens a recirculation conduit between the container and the valve assembly. The liquid is circulated via a circuit formed by the container, the pump conduit, the valve assembly and the recirculation unit.
