Hydraulic Diaphragm Pump Method and Apparatus Abstract A hydraulically activated diaphragm pump. A pressure source is coupled to a pump diaphragm during a pump discharge stroke. During this discharge stroke, an air activated return assist cylinder is vented to atmosphere. On the return stroke the pump housing above the diaphragm is vented and the air cylinder activated. A single 4- way solenoid actuated valve controlled by an adjustable timer accomplishes this cylic pumping action. The timer is adjustable to set the number of pump cycles per minute and also adjusts the discharge stroke period of each cycle.
