ABSTRACT:
A fluid pump is disclosed herein having a frame defining an internal pumping chamber in combination with a flexible diaphragm. A top ring retains the diaphragm in position on the frame and includes a central area carrying an actuation mechanism for cyclically maintaining the fluid pumping operation in the pumping chamber. Inlet and outlet valves are disposed in the frame and interconnected with the pumping chamber to complete the pump. The actuation mechanism includes a motor-driven eccentric cam coupled to the central diaphragm area with top surface attachment only.
