Electric Diaphragm Pumps

Electric Operated Double Diaphragm Pumps (EODD) use an electric motor to drive flexible diaphragms, providing smooth fluid transfer with low noise and energy efficiency, making them ideal for long-duration continuous operation in automated smart production lines. Graco's Quantm auto shutoff under back pressure, eliminating air compressor needs and reducing energy and noise.

Difference Between Air-Operated and Electric Pumps

Diaphragm pumps come in two main types: Air-Operated Double Diaphragm (AODD) and Electric Operated Double Diaphragm (EODD).
AODD pumps use compressed air to drive diaphragms back and forth, resulting in high energy consumption and loud exhaust noise.
EODD pumps, in contrast, use an electric motor for precise speed control, continuous flow, and quiet, energy-efficient operation, with VFD and I/O support for smart production integration.

8x Continuous Torque – More Power, Less Wear

Quantm pumps use a patented FluxCore direct-drive motor, integrating a flux-concentrated stator and direct-drive eccentric shaft for higher torque without a gearbox. This design reduces wear, noise, and maintenance, delivering quieter, more efficient performance in the same compact size.

Smart Back-Pressure Shutdown Protection

The only EODD pump on the market with automatic back-pressure shutdown, stopping the pump when idle without the need for pressure sensors or external controls, preventing damage from pipeline blockages or closed valves.

Quieter Operation, Smaller Footprint

Unlike air pumps, which generate loud exhaust noise and compressor hum, electric pumps run quietly with only motor rotation, eliminating the need for noisy air supply. Tests show up to 23 dBA noise reduction, cutting sound intensity by 90%, significantly improving workplace conditions.

Real-Time Leak Protection System

The QUANTM electric double diaphragm pump is equipped with a leak detector installed inside the pump’s control housing. It is connected to the pump’s diaphragm chamber via a dedicated line. When a diaphragm rupture causes leakage, fluid enters the sensor area of the detector, immediately triggering the yellow LED warning light on the pump and automatically stopping pump operation to prevent further leakage or equipment damage.

Multiple Sizes and Wetted Material Options

Quantm pumps are available in various sizes and wetted materials:
• Aluminum – Ideal for oils and coolants
• Stainless Steel – Suitable for corrosive liquids or particle-laden fluids
• Polypropylene (PP) – Great for acids, alkalis, and explosive environments
• PVDF – Designed for high-corrosion and high-purity chemicals

High Efficiency, Quick Payback in 12–24 Months

According to Graco's energy comparison, Quantm EODD pumps achieve an 83% energy efficiency, generating $0.83 of effective output per $1 of electricity – about 5 times more efficient than traditional AODD pumps.
For example, a 2" i120 Quantm pump has a rated power of just 1.8 kW, while a similar flow AODD system typically requires a 4-6 kW air compressor. Over 4,000 hours of annual operation, this can save 12-17 MWh in energy costs alone. Factoring in compressor maintenance, noise control, and cooling costs, most customers recover the initial investment within 12-24 months, despite a higher upfront cost.
