Abstract
An improved adhesive pump and pump control system for automatically changing the flow rate of adhesive materials being dispensed onto a workpiece in conformance with changes in movement of a robot controlled adhesive dispensing nozzle used to apply adhesive materials automatically onto the surface of the workpiece in accordance with a predetermined pattern. The system includes an improved adhesive gear pump having a novel sealing arrangement which employs lubricant grease supplied under pressure for preventing leakage of the adhesive along the shaft into the bearings of the pump thereby assuring long and reliable operating life for the pump under normal operating conditions.
