Electric operated diaphragm pumps, commonly referred to as EODD pumps, use an electric motor and mechanical drive to operate the diaphragm rather than compressed air.
This technology removes the inefficiencies associated with air systems, offering lower energy consumption, improved control and reduced maintenance, while retaining the core advantages of diaphragm pumps, including sealless operation, self-priming capability and the ability to handle difficult fluids.
EODD pumps are increasingly popular across manufacturing, process industries, chemical processing and wastewater applications for energy reduction, process control and system simplification.
Electric diaphragm pumps are commonly used for:
Chemical transfer and blending
Paints, coatings, pigments and inks
Slurry, abrasive and viscous fluids
Industrial wastewater, sludge and recycling processes
General process transfer where leak reduction is critical

While air operated diaphragm pumps remain suitable for some intermittent or hazardous environments, EODD pumps offer clear advantages where compressed air infrastructure is costly, inefficient or difficult to control.
EODD pumps are often selected when:
Energy consumption needs to be reduced
Flow and pressure control are important
Maintenance time and system complexity must be minimised
Continuous or long duty cycles are required
Pumps & Gearboxes supports both technologies, allowing us to provide unbiased, application-focused advice when selecting between EODD and AODD solutions.
An EODD pump uses an electrically driven mechanism to reciprocate the diaphragm, creating suction and discharge without the need for compressed air.
This allows operators to achieve:
Consistent, controllable flow and pressure
Reduced energy losses compared to pneumatic systems
Cleaner, quieter operation
Improved efficiency in continuous or duty-critical processes
EODD pumps maintain the inherent strengths of diaphragm technology, including leak resistance, dry-running capability and solids handling, while significantly improving overall system efficiency.
