Abstract
A double diaphragm pump for moving large volumes of water that may be laden with debris includes a pair of fourteen-inch diameter elastomeric diaphragms, driven by reciprocating push rods pivotally coupled to opposed eccentrics. An engine drives a gearbox having two outputs. One eccentric is attached to each output. A pair of weighted flap valves control flow to and from each diaphragm chamber. A vacuum pressure gauge monitors inlet pressure. A relief valve relieves vacuum pressure in the event of a blockage or other flow impediment.
