Multi-station viscous liquid distribution system

A system for dispensing multiple discrete streams of high viscosity liquids from a common liquid source comprising:

• a distribution manifold,
• a plurality of extrusion guns, each of said guns being independently operable to dispense said liquid in a stream onto a workpiece when activated,
• a plurality of connector lines, each of said connector lines having an input end connected to said distribution manifold and a discharge end connected to a different one of said guns,
• a multi-speed primary pump connected between said source and said distribution manifold for supplying said liquid to said distribution manifold at high pressure,
• a motor and motor speed control means for effecting different discrete speeds of said multi-speed primary pump in response to each different combinations of guns activated at any time so that the dispensing rate of the guns remains substantially the same as different combination of guns are activated.
