Automatic Double Diaphragm Pumping System (1)

As the well charges, fluid rises above the downwell level sensor. When approximately 9 inches (23 cm) of fluid is detected, the air flow control is signaled and compressed air is introduced into the double diaphragm pump. The diaphragms then move back and forth creating a vacuum that draws in fluid. When the fluid level is reduced to about 6 inches (15 cm) above the end of the sensor and no longer detected, the pump turns off. Fluid then continues to enter the well, raising the water level, and the cycle repeats itself.
