ABSTRACT:
A pump for precision metered pumping of high viscosity materials. A pump housing has a material inlet and a material outlet, a drive gear and at least one cooperating driven gear for receiving material from the material inlet and pumping a metered amount of material to and out of the material outlet. A motor rotates the drive gear, and an impeller also driven by the motor feeds material under positive pressure into the material inlet where the material is metered and pumped downstream into the outlet.
