How Does an Electric Diaphragm Pump Work?
An electric diaphragm pump is a positive displacement pump that uses reciprocating diaphragms to move fluid through the pump. While traditional air-operated diaphragm pumps use compressed air as their power source, an electric diaphragm pump uses an electric drive to generate the pumping action.
As the diaphragms move back and forth, fluid is drawn into one chamber through the inlet before being displaced through the outlet, while the opposite chamber completes the corresponding cycle. This continuous alternating action enables controlled fluid transfer while retaining many of the characteristics associated with diaphragm pump technology.
These pumps are available with ball check valves or flap type check valves for handling sheer sensitive products and products with large particles that require gentle handling.
Benefits of Electric Diaphragm Pumps
- Up to 80% more energy efficient than traditional air-operated diaphragm pumps
- Energy-efficient electric drive can significantly reduce compressed-air consumption and energy use
- Stall-under-pressure capability helps protect the pump from closed valves or blocked lines
- Reduced pulsation without the need for additional pulsation dampeners
- Seal-less diaphragm pump design helps reduce the risk of leaks and failures
- Suitable for dry-running operation
- Self-priming, with no need to fill the pump before operation
- Mobile cart options available for easier movement between applications
- ATEX configurations available for suitable operating environments
Choosing an Electric-Driven Diaphragm Pump
Choosing the right electric-driven diaphragm pump depends on factors including required flow rate, fluid characteristics, materials of construction and the operating environment. The correct configuration should also account for the required level of pump control and whether specific requirements such as ATEX compatibility apply.

Electric Diaphragm Pump FAQs
An electric diaphragm pump is a positive displacement pump that uses an electric drive to operate reciprocating diaphragms. This pumping action draws fluid into the pump and then displaces it through the outlet.
The primary difference is the power source. An air-operated diaphragm pump relies on compressed air, while an electric diaphragm pump uses an electric drive. This can reduce reliance on compressed-air systems while retaining many of the operating characteristics associated with diaphragm pumps.
Electric diaphragm pumps can be used for a range of fluid-transfer applications where self-priming capability, dry-running operation, reduced pulsation or electrically driven operation are required.
The appropriate model and configuration depend on factors such as required flow, fluid properties, material compatibility and operating conditions. Dura Pump can help assess the application and recommend a suitable configuration.
