Abstract
A gear pump for mixing first and second components includes an inlet port, a premix chamber, and a second component valve. The premix chamber has a first end communicating with the inlet port, and a second end communicating with a source of the first component, thus providing a fluid path to carry the first component through the inlet port upon operation of the gear pump. The second component valve regulates fluid communication between a source of the second component and the premix chamber. Upon operation of the gear pump, the first component is drawn from its source into the premix chamber, the second component is drawn from its source, through the second component valve, and into the premix chamber, and a premix of the first and second components is fed from the premix chamber through said inlet port.
