Abstract

A paint spraying machine for applying plural component coating materials with a component A and a component B, the machine having separate hoppers for each component in which the components A and B are held respectively, a pump operable to separately pressurize the components to independently selected pressures for each component, where the pump includes a separate pump lower for each component, a mix manifold configured to receive the components separately from the pump and mix the components to a selected, fixed mix ratio, manually operated controls adjustable to control flow of the components through the machine, and a spray line including a spray gun operable to spray the mixed and pressurized components. The fixed mix ratio is determined by the volumetric displacement of the pump lowers selected. The components remain separate until combined together in the mix manifold forming the coating.
