ABSTRACT:
A pump having a diaphragm positioned within a diaphragm housing comprised of an air cap and a fluid cap. The air cap and fluid cap include inner surfaces that cooperate to define a diaphragm chamber in which the diaphragm moves between a withdrawn deformed position and an extended deformed position. The inner surfaces of the air cap and fluid cap are designed to fully accommodate the movement of the diaphragm between its withdrawn deformed position and an extended deformed position. Finite element analysis is used to estimate the diaphragm's withdrawn deformed position and an extended deformed position.
