61204X-X 2-Ball Piston Pump & Packages

  • 1:1 Ratio
  • 2" Air Motor
  • 18 GPM (68.1 LPM) Max Flow
  • Max Fluid: 150 psi

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 coating 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 pumps generate pressure to handle extrusion of low- to medium- viscosity
Lubrication: ARO 2-balls pumps provide 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
