KEY BENEFITS
  • Self-Priming

The QUANTM EODD pump is self-priming and delivers excellent suction performance.

  • Seal-Less Design

Its seal-less diaphragm design eliminates costly rotary seals, reducing spare part expenses and minimizing downtime.

  • Stalls Under Pressure

The QUANTM EODD is the only electric diaphragm pump that stalls under pressure without requiring sensors or extra controllers, preventing damage from clogged lines or closed valves.

  • Run Dry Capability

The pump can run dry without causing system damage, avoiding costly repairs.

  • Low Operating Costs

Its energy-efficient electric drive can reduce energy consumption by up to 80% compared to pneumatic systems.

  • Quiet Operation

Without the need for an air motor muffler, the QUANTM EODD runs much quieter than traditional AODD pumps.

  • Wide Operating Range

It handles varying flow rates, pressures, and applications safely, including shear-sensitive fluids, abrasives, and solids. The pump can also be configured with a variety of materials to suit most processes.

  • Compact Footprint

The pump’s small design saves valuable floor space.

  • Low Shear

QUANTM pumps provide gentle pumping action, minimizing the breakdown of sensitive materials.

Other industrial pump types Graco QUANTM EODD pumps
Narrow best efficiency point and preferred operating range Consistent reliability over operating range
Deadhead/stall causes severe damage Easily deadhead/stall with no additional equipment
Expensive/complex repair Easy to repair at low cost
Process changes can lead to cavitation No degradation due to changing conditions
Difficult to choose correct pump Simple pump selection (pressure/flow/chemical composition)
Shaft alignment difficult to maintain No spinning shaft seals; no alignment necessary
Not self-priming Excellent self-priming
High operating cost Energy-efficient drive; low operating cost
Damaged when running dry Can run dry indefinitely
