AF1045 Series 2-Ball Piston Pumps

  • 45:1 Ratio
  • 10" Air Motor
  • Max Flow: 6.27 GPM (23.7 l/min)
  • Max Fluid Pressure: 4,050 psi (279.3 bar)

About the range of ARO 2-ball pneumatic piston Pumps: The most versatile piston 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).

Applications advantages of 2-balls:

  • Spray: 2-ball pumps deliver the constant flow rate andpressure needed for consistent and efficient coatingsapplications
  • Transfer & Supply: Depending on themodel, 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 andgrease lubricants
  • High Pressure Cleaning: ARO® WashPump Packages are portable and offer the the right option forindustrial 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
