Air Operated Pumps:

An AOD style pump has at least 50% more moving parts than a mechanical
diaphragm pump. This may require higher repair costs.

It may be difficult to repair an air operated diaphragm pump, as most working
parts are very small and internal.

AOD pumps may be more expensive. Air compressors are required to operate
pump and require their own maintenance program.

AOD style pumps require more power and are less efficient, since energy is
transferred from motor to compressor and then to the pump.

Multiple air hoses are required to drive the pump. These hoses frequently
leak, causing wasted energy.

AOD pumps require compressed air. Compressed air is not always available
where the pump needs to be located.

AOD pumps are noisier than mechanically driven pumps due to the
reciprocating motion of the high pressure air and compressor.

Difficult to remove AOD pump blockages, because of the amount of
elbows and turns that the fluid needs to make in the pump.

No visual inspection of diaphragm can be made without opening pump cavity.

Due to the amount of turns and bends the fluid needs to make, there is a
higher risk of clogs and overall efficiency loss.
