Abstract
A fluid dispenser is disclosed for dispensing multiple fluids and that includes valve assemblies with rotary recirculation and dispense valves. A table controlled by a motor and a controller moves all of the valve assemblies to either a dispense position or a recirculation position together. The controller selectively operates the pump motors associated with individual canisters of fluid so that the system can dispense a single fluid or multiple fluids at a time. When in the recirculation position, the fluids can be continuously, intermittently or periodically recirculated to maintain the fluids in a homogenous state.
