Abstract: A method of actuating a double-action pump assembly with a reciprocating plunger includes signaling the reciprocating plunger to stop for a changeover period; while the pump is stopping, signaling the first inlet and outlet valves to close; while the first inlet and outlet valves are closing, signaling the second inlet and outlet valves to open, such that the second inlet and outlet valves begin to mechanically open at least a dwell period after the first inlet and outlet valves have entirely closed; and signaling the reciprocating plunger to begin moving while the second inlet and outlet valves are closing.

Abstract: A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a target primary-to-secondary spray component flow ratio, sensing an output pressure of the first pump, controlling the first pump to a first speed set via a proportional-integral-derivative loop using the sensed output pressure and the target spray pressure, and controlling the second pump to a second speed equal to the first speed multiplied by the target primary-to-secondary spray component flow ratio.
