Patent ID: 8801404

Claim:
A method for optimizing an amount of supply compressed air utilized during operation of a pump, comprising: determining that a first current position (X CL ) for a first diaphragm assembly of the pump has met a first turndown position (X SL ), using a first sensor configured to detect the first diaphragm assembly at the first turndown position (X SL ), 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 (EOS 1 ) and the first turndown position (X SL ), the first turndown position (X SL ) comprising a different position of the first diaphragm assembly in the first diaphragm chamber than the first end-of-stroke position (EOS 1 ); and a second diaphragm assembly disposed in a second diaphragm chamber, wherein the second diaphragm assembly comprises a second end-of-stroke position (EOS 2 ) and a second turndown position-(X SR ), the second turndown position-(X SR ) comprising a different position of the second diaphragm assembly in the second diaphragm chamber than the second end-of-stroke position (EOS 2 ); decreasing supply compressed air to the first diaphragm chamber upon determining that the first current position (X CL ) has met the first turndown position (X SL ); and increasing supply compressed air to the second diaphragm chamber upon determining that the first current position (X CL ) has met the first end-of-stroke position (EOS 1 ), using a second sensor configured to detect the first diaphragm assembly at the first end-of-stroke position (EOS 1 ).
