As industries demand higher efficiency, lower costs, and greater reliability in fluid transfer systems, diaphragm pump technology has become an essential part of modern manufacturing and processing operations. Among the most significant innovations in this field is the electric diaphragm pump, which offers the same robust performance as pneumatic models while greatly improving energy efficiency and control.
For decades, air operated diaphragm pumps have powered critical processes in sectors such as manufacturing, mining, chemical production, and wastewater treatment. Now, with sustainability and operational cost reduction becoming central to industrial strategy, companies are rethinking how their pumping systems are powered. Ovell Pump, a trusted diaphragm pump manufacturer, has been at the forefront of this evolution, providing efficient, reliable, and high-performance solutions designed for long-term industrial use.
From Air to Electric
Diaphragm pumps are widely recognised for their ability to handle challenging materials, including abrasive slurries, corrosive fluids, and viscous substances.
Traditional pneumatic diaphragm pumps rely on compressed air to move diaphragms back and forth, creating suction and discharge strokes. This long-proven technology offers many operational benefits:
Safe, spark-free operation Pneumatic pumps are driven by air rather than electricity, making them ideal for environments where flammable gases, vapours, or liquids are present. Their design inherently eliminates spark risk, ensuring safe use in chemical plants and hazardous zones.
Ability to handle thick or abrasive fluids These pumps can manage high-viscosity materials and slurries without clogging, thanks to their strong suction capability and minimal shear transfer. This makes them suitable for ceramics, adhesives, and paint applications.
Simple design and straightforward maintenance With relatively few moving parts and no need for lubricants, pneumatic diaphragm pumps are easy to maintain and service, resulting in long operational lifespans and dependable uptime.
However, as energy efficiency became a higher priority, industries began to identify the limitations of air-powered systems, including:
High energy consumption due to compressor inefficiencies and air leakage
Pressure losses caused by friction and piping constraints
Noise and heat generated by continuous air compression
To overcome these issues, the electric diaphragm pump was developed. Using an electric motor instead of compressed air, this design maintains the diaphragm’s proven mechanical motion but introduces several modern advantages:
Precise flow control for consistent output and improved dosing accuracy
Lower operating costs by reducing reliance on compressed air systems
Quieter, smoother operation with less vibration and energy waste
Simplified system setup, requiring only a power source, not a full air infrastructure
Recognising the potential for improvement, Ovell Pump engineered a line of electric diaphragm pumps that maintain reliability while offering superior efficiency and control across a wide range of industrial applications.
Inside the Electric Diaphragm Pump
An electric diaphragm pump uses a motor-driven crankshaft to alternately flex two diaphragms, creating suction and discharge cycles. This system mirrors the air-driven design but introduces significant performance and reliability upgrades.
Key engineering features include:
Back pressure protection This built-in mechanism helps stabilise output flow and pressure. It prevents excess strain on diaphragms and internal components, significantly extending pump life and maintaining consistent performance even in variable operating conditions.
Leakage alarm and automatic shutdown Integrated sensors and pressure monitoring provide instant feedback if leakage or pressure imbalance occurs. The automatic stop feature ensures safety for both personnel and equipment, preventing contamination or damage during operation.
Smooth and steady flow output Electric pumps maintain constant pressure and flow, reducing pulsation without requiring external dampers. This consistency enhances system stability and protects connected equipment such as valves, filters, and meters.
Self-priming capability Ovell’s electric pumps can start operation without manual priming, enabling faster setup and improved operational convenience. This feature is especially useful in installations where liquid levels fluctuate or suction lift is required.
Dry-run protection The diaphragm design allows temporary operation without liquid, avoiding mechanical failure during fluid shortages and enhancing reliability during startup or shutdown procedures.
Compared with traditional air-driven models, Ovell’s electric diaphragm pumps can:
Reduce overall energy use by up to 70%, offering substantial cost savings
Maintain a consistent discharge pressure, reducing wear on downstream systems
Minimise vibration, resulting in quieter operation and longer equipment life
Simplify maintenance routines by removing the need for air compressors or pneumatic controls
These advantages make Ovell’s pumps an ideal solution for facilities seeking both sustainability and high operational performance.

Generally louder during operation due to exhaust noise from air release.
Requires periodic maintenance of air lines and valves to sustain optimal performance.
Electric Diaphragm Pumps
Powered by an electric motor, offering direct mechanical control.
Highly energy-efficient, converting most of the power directly into fluid movement.
Quiet operation with minimal vibration, improving the work environment.
