This invention provides a double-acting, double diaphragm pump particularly for fluids such as chemical compounds. The pump employs adjustable disk members mounted on a reciprocable rod connecting and actuating the diaphragms. These disks alternately engage the extending shaft of a pilot valve to move the valve and redirect the flow of pressurized fluid therethrough. The pressurized fluid behind the diaphragm is now caused to flow to a slide valve and cause it to be moved to an opposite limit. The slide valve is cycled by the pilot valves as the disks on...
1. A double-acting, pressurized fluid-actuated double diaphragm pump for fluids and the like, said pump including: (a) a main pump housing support adapted for mounting to a support means; (b) a first pump housing means attachable to said main pump housing support, the first housing means including inner and outer diaphragm housing members with the outer members having inlet and outlet valve means providing one-way flow control of the pumped fluid; (c) a first diaphragm interposed between said inner and outer housing members and means for securing th...
