Abstract
A plural material dispensing system () includes a pump () having a cylinder () mounted between a first bracket () and a second bracket (), a piston () disposed within the cylinder (), and a pump rod () extending from the piston () and out of the first bracket (). Material is provided to the cylinder () through a flow path extending through the pump rod (). The piston () drives material downstream out of the cylinder (), and the interface between the piston () and the inner surface of the cylinder () provides a dynamic seal during pumping. The flow of material into and out of the pump () is controlled by actively-controlled inlet and outlet valves.
