<p>An air operated double diaphragm pump comprises an integrated electric generator and an air efficiency device. The integrated electric generator increases the portability of the air operated double diaphragm pump. The air efficiency device varies the amount of compressed fluid entering the pump between a high volume and a low volume dependent upon the velocity and position of the pump's diaphragm assemblies to optimize the pump's efficient use of the compressed air.</p> |
