An intensifier pump system includes a supply pump for delivering fluid products at an intermediate pressure. The products are delivered to one or more intensifier pumps that take advantage of hydraulic intensification to expel the product at high pressures to assure continuous product deployment in various systems. After an extension cycle in one of the intensifier pumps, product is delivered from the supply pump at a pressure sufficient to retract the intensifier pump and fill the chamber with fluid.
