ABSTRACT:
The invention involves an improved design for a diaphragm pump. The inlet and outlet valves for the pump have guided stems that prevent the valves from misaligning and jamming during operation. The stems extend away from each other enabling the valve heads to be moved close to each other so that the pump bowl can be made relatively short. The pump diaphragms include rim portions that cover and protect the members securing it in the pump. The stroke of the pump is adjustable by an arrangement that can vary the size of the stroke while keeping the suction and discharge portions of the stroke equal.
