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. When suction is applied to the internal surface of the piston the button diaphragm, is aligned with the piston by the button, and the diaphragm is drawn toward the face of the piston, thereby ensuring the diaphragm is properly seated on the piston during operation of the piston pump.
