More Information
Summary:A diaphragm pump includes a pumping chamber for pumped fluid and a hydraulic chamber. A diaphragm has a pumping chamber side and a hydraulic chamber side. The pumping chamber side of the diaphragm is proximate the pumping chamber and acts on the pumped fluid. The hydraulic chamber side of the diaphragm is proximate the hydraulic chamber. A plunger is in fluid communication with the hydraulic chamber and acts on the hydraulic fluid, which acts on the diaphragm. A plunger driver imparts reciprocal motion to the plunger. The pump includes a sensor assembly sensing position and direction of the plunger and sensing position of the diaphragm. By sensing the position of the diaphragm, hydraulic fluid flow is controlled by a control single valve.
