Abstract
Disclosed herein is a wobble diaphragm pump having a housing with an open neck. A wobble piston can be passed through the open neck and fit onto the pump motor shaft. A separate support ring is fastened to the housing to close the open neck and provide a circumferential support surface for the diaphragm. The support ring also includes locking projections that mate with recessed features in the housing and a valve head to properly align and unite these components during assembly.
