Method for increasing compressed air efficiency in a pump

A method for optimizing an amount of supply compressed air utilized during operation of a pump, comprising:

• determining that a first current position (XCL) for a first diaphragm assembly of the pump has met a first turndown position (XSL), using a first sensor configured to detect the first diaphragm assembly at the first turndown position (XSL), the pump comprising:
• the first diaphragm assembly disposed in a first diaphragm chamber, wherein the first diaphragm assembly comprises a first end-of-stroke position (EOS1) and the first turndown position (XSL), the first turndown position (XSL) comprising a different position of the first diaphragm assembly in the first diaphragm chamber than the first end-of-stroke position (EOS1);
• and
• a second diaphragm assembly disposed in a second diaphragm chamber, wherein the second diaphragm assembly comprises a second end-of-stroke position (EOS2) and a second turndown position-(XSR), the second turndown position-(XSR) comprising a different position of the second diaphragm assembly in the second diaphragm chamber than the second end-of-stroke position (EOS2);
• decreasing supply compressed air to the first diaphragm chamber upon determining that the first current position (XCL) has met the first turndown position (XSL);
• and
• increasing supply compressed air to the second diaphragm chamber upon determining that the first current position (XCL) has met the first end-of-stroke position (EOS1), using a second sensor configured to detect the first diaphragm assembly at the first end-of-stroke position (EOS1).
