  • Patent number: 9850889
    Abstract: A hydraulic fluid control system for a hydraulic diaphragm pump including at least one hydraulic diaphragm containing a process fluid surrounded by at least one hydraulic fluid chamber containing a hydraulic fluid is provided. The system includes a differential pressure sensor operable to detect and measure a pressure difference between the process fluid contained in the at least one hydraulic diaphragm and the hydraulic fluid contained in the at least one hydraulic fluid chamber; a hydraulic fluid reservoir containing hydraulic fluid; and a hydraulic fluid pump fluidly connected to the hydraulic fluid reservoir and the at least one hydraulic fluid chamber, and operable to provide a volume of hydraulic fluid to the at least one hydraulic fluid chamber in response to the pressure difference measured by the differential pressure sensor. The system is optionally operable to withdraw a volume of hydraulic fluid from the hydraulic fluid chamber.
