Abstract
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.
Claims20
A pump comprising:
- a first diaphragm assembly, wherein the first diaphragm assembly is disposed in a first chamber and includes a first diaphragm forming a first pumping chamber and a first diaphragm chamber within the first chamber;
- a second diaphragm assembly, wherein the second diaphragm assembly is disposed in a second chamber and includes a second diaphragm forming a second pumping chamber and a second diaphragm chamber within the second chamber, wherein a connecting rod is operatively connected to the first and the second diaphragms and allows the first and the second diaphragm assemblies to reciprocate together between a first diaphragm position and a second diaphragm position;
- a center section, wherein the center section at least partially causes a compressed fluid to be alternately supplied to or exhausted from the first and the second diaphragm chambers, and;
- an integrated power supply, wherein the integrated power supply utilizes compressed air supplied to the pump to supply power to at least a first component of the pump.

A method for supplying power to a pump, the method comprising the steps of:
- providing a first diaphragm assembly, wherein the first diaphragm assembly is disposed in a first chamber and includes a first diaphragm forming a first pumping chamber and a first diaphragm chamber within the first chamber;
- a second diaphragm assembly, wherein the second diaphragm assembly is disposed in a second chamber and includes a second diaphragm forming a second pumping chamber and a second diaphragm chamber within the second chamber, wherein a connecting rod is operatively connected to the first and the second diaphragms and allows the first and the second diaphragm assemblies to reciprocate together between a first diaphragm position and a second diaphragm position;
- a center section, wherein the center section at least partially causes a compressed fluid to be alternately supplied to or exhausted from the first and the second diaphragm chambers, and;
- an integrated power supply;
- generating electrical power, wherein the integrated power supply generates electrical power utilizing compressed air supplied to the pump.
