Features & benefits
Low energy cost
Electricity cost < compressed air cost, high efficient (IE3 class) drive
Long diaphragm lifetime
Pneumatic and mechanical support of the diaphragm
Run dry without damage
Easy to use, no need of guarding device
Low spare parts cost
Pump has almost identical design of the wetted side as standard Tapflo air operated diaphragm pump therefore many spare parts are the same
Self-priming from dry suction pipe
More options of installation
Clean & easy maintenance
No hydraulic fluid required, no danger of leakage
Few components & long life design
Low downtime and maintenance cost
The total operating cost
The purchase price of an AODD pump is essentially lower than the Electrically operated one. However, the operating costs of AODD outweigh the ones of EODD significantly. When the pump price/cost balance is considered, after 1-2 years of operation (depending on the pump size and configuration) the fundamentally lower operating costs of an EODD make up for its higher purchase price in comparison to the standard AODD pumps.
