초록

The fluid-operated, double diaphragm pump of the invention includes a central housing block having opposed side faces, and a pair of diaphragm housing end sections secured to opposite sides of the central housing block. The diaphragm housings define a pair of enclosures having a common central axis. Mounted in each of the diaphragm housings is a diaphragm that serves to divide each enclosure into an inner pumping chamber, defined by a side face of the housing block and the diaphragm, and a drive chamber defined by the opposite side of the diaphragm and, ...
