Abstract
An apparatus for supplying electrically conductive coating material, such as water-based paint, includes a manifold connected to a high voltage electrostatic power supply and to one or more coating dispensers, and, a number of coating transfer units which are movable between a discharge position or station at the manifold and a filling station physically spaced from the manifold. Each of the transfer units includes a combined shuttle and pumping device which initially receives coating material at the filling station, and is then movable to the discharge station where the coating material is transferred from the pumping device, through the manifold, and then to one or more coating dispensers for deposition onto a substrate.
