ABSTRACT:
Apparatus for an improved diaphragm pump wherein hydraulic shock and mechanical wear to the diaphragm membrane is reduced by providing a circular reed valve member adjacent to the diaphragm. The reed valve member provides a barrier to pressurized hydraulic fluid jets from direct impingement upon the diaphragm membrane, and provides a valve closure member for reducing hydraulic shock effects on the diaphragm membrane.
