Abstract
A pumping system for delivering unstable fluids under pressure, comprising a pair of alternately operated single-acting pumps operated by a double-acting air motor. The air motor is controlled by a reversible spool valve and mechanically operated air pilot valves. The single-acting pumps deliver and contain relatively small quantities of the unstable fluid to a positive flow metering system for connection to an outlet to spray guns or other equipment using the fluid. The metering system includes a metering valve, a flow meter and a bypass valve for removing trapped air and presetting flow.
