AF0828B Series 2-Ball Piston Pump

  • 28:1 Ratio
  • 8" Air Motor
  • Max Flow: 6.27 GPM (23.7 LPM)
  • Max Fluid Pressure: 3,360 psi (231.6 bar)

About the 2-Ball piston pump range of ARO: The most versatile pumps in the ARO line. They are capable of handling applications from simple transfer to the extrusion of low to medium viscosity materials up to 100,000 centipoise (cPs) with fluid delivery up to 18 gpm (68.6 l/min).

Simply Versatile

2-ball pumps are among the most versatile in the ARO line. They are capable of handling applications from simple transfer to the extrusion of low- to medium- viscosity materials up to 100,000 centipoise (cPs) with fluid delivery up to 18.1 gpm (68.6 L/min).

Applications advantages of 2-balls:

  • Spray: 2-ball pumps deliver the constant flow rate and pressure needed for consistent and efficient coatings applications
  • Transfer & Supply: Depending on the model, some 2-ball pumps can achieve flow rates up to 18.1 gpm, providing dependable results
  • Extrusion: 2-ball pumpsgenerate pressure to handle extrusion of low-tomedium-viscosity
  • Lubrication: ARO® 2-balls pumpsprovide the flow and pressure required for moving light oils and grease lubricants
  • High Pressure Cleaning: ARO® Wash Pump Packages are portable and offer the the right option for industrial cleaning applications

Materials advantages of 2-balls:

  • Sheer sensitive materials: ARO® 2-ball pumps minimize friction points to prevent fluid shear, when compared to other similar pumping technologies
  • Abrasive and high solid materials: ARO 2-ball pump minimize friction points and allow smooth passages to maintain fluid consistency
  • Optional ceramic coating provides an even stronger defense against highly abrasive fluids like paint and glass-filled sealer
