    Abstract: A liquid pumping, handling and spraying system for liquid compositions and especially those liquid coating compositions having a suspension of metal particulate therein which tends to settle out of suspension of metal particulate therein which tends to settle out of suspension quite rapidly and which includes metal particulate having an affinity for adherence to metal surfaces. A fluid supply system is provided which accomplishes continuous agitation of the liquid composition to sprayed to maintain the metal particulate thereof in properly entrained suspension and even distribution with the liquid carrier fluid and which permits the use of low cost, lightweight containers for the liquid supply. A packingless pump is provided for pressurized delivery of the liquid composition from the supply container to a packingless spray gun. The packingless pump achieves pumping of liquid by hydro mechanical deformation of polymer variable volume pump chambers which induce intermittent suction and pressurization of the liquid for pumping and which have externally mounted check valve heads for controlling the flowing of the pumped liquid from the supply container to the spray gun. The packingless spray gun employs a body of resilient polymer which functions as a columnar spring to control the opening and closing movement of a spray valve assembly. Valve seats of the check valve head and spray gun assembly may be of flexible nature to ensure efficient separation of metal particulate therefrom. Metal operational components of the check valve head and spray gun, such as valve stems and valves define outer surfaces composed of titanium to minimize metal particulate adherence thereto.
