Graco’s Electric AODD Pumps Eliminate Drawbacks of Traditional Pump Technologies

Posted on by Sara Springer

If you are looking for an innovative pump designed to overcome common fluid handling problems associated with conventional pumps, consider Graco’s EODD pump (Electrically Operated Double Diaphragm).

These common problems include:

  • Damage caused by Running Dry
  • Inability to ‘Dry Prime’
  • Over-pressure damage caused by closed or blocked discharge

Centrifugal Pumps:

  • Not suited for abrasives or solids, damage to impellers
  • High shear causes product damage
  • Minimal flow rate adjustments capabilities
  • Need stable system conditions for optimal performance

Magnetic Drive Pumps:

  • Restricted to clean liquid applications
  • Magnets generate heat that transfers to fluid during processing

Rotary Lobe Pumps:

  • Require timing gears and additional maintenance
  • Lack of performance with low viscosity fluids

Gear Pumps:

  • Sensitive design resulting in constant, expensive maintenance/replacement parts
  • unsuitable for operations with large bulk flow rates

Progressive Cavity Pumps:

  • Requires constant lubrication
  • Rotation of shaft and mechanical seal creates friction, transferring heat to fluids
  • Mechanical seals require maintenance and costly replacement

Peristaltic Pumps:

  • Large footprint
  • High maintenance costs
  • Frequent replacement of hoses

Innovative features that will get you excited to make the upgrade to a Graco® Electric AODD Pump:

  • Self-priming / Dry-Priming with excellent suction capabilities
  • Seal-less diaphragm design eliminates rotational seals, saving time and money
  • Integral controls
  • Standard
    • Variable flow via VFD (sold separately)
    • Variable pressure (integral)
    • Eliminates the need for external Bypass Pressure-relief valves
  • BLDC Drive package provides
    • Variable Flow and Pressure
    • Manual, Remote, or Automatic
    • Batch Dispense Mode: the pump dispenses a preset volume. Stalls under pressure without the need for pressure sensors and additional controllers, to prevent pump failures from clogged lines or closed valves.
  • Runs Dry infinitely
  • Low operating costs, energy-efficient
  • Quiet operation
  • Wide operating range, ideal for applications including varying flow, pressure, shear sensitivity, abrasives, and solids
  • Small footprint
