Abstract
An apparatus is provided for transferring electrically conductive coating materials, such as water-based paint, from a source to at least one coating dispenser such as a spray gun for discharge onto a substrate. In alternative embodiments, the coating material is supplied to the dispenser(s) from parallel flow paths which are comparatively simple and inexpensive in construction, and which are capable of delivering high pressure, high volume flows of coating material while substantially eliminating pressure fluctuations in the coating material supply when switching from one flow path to another.
