Abstract
A system for dispensing multiple discrete streams of a high viscosity liquid material, and particularly, systems such as those for applying sealants to the seams of an automobile body on a production line. The system is provided with a multi-speed pump for supplying the viscous liquid from a reservoir at high pressure to a distribution manifold from which it is distributed at regulated rates to a plurality of extrusion guns through drop lines from the manifold. A motor speed control which is settable to a number of predetermined motor operating speeds which selects the speed of the multi-speed pump in response to the combination of guns which is activated, so that the dispensing rate can remain the same regardless of which other guns are activated. Regulators which include volumetric metering pumps are included in the drop lines at each of the guns, with controls coordinated with the motor speed control.
