Abstract:
A system, method, and process of using a button diaphragm for a piston pump are provided. The button diaphragm is a thin sheet of material with a raised bead located on its periphery. The button diaphragm also has a button with a button face and a relief. The button is centered and inserted into a mating receptacle on a piston pump thereby aligning the diaphragm on the piston.
