  • Type of Fluid
  • Viscosity or thickness
  • Required flow rate
  • Required output pressure

    2-ball pumps are among most versatile in the ARO line.
    Capabile of handling applications from simple transfer to the extrution of
    low to medium viscosity materials up to 100,000 centipoise (cPS) with fluiddelivery up to 18.1 gpm (68.6 L/min)

  • Spray: 2-ball pumps deliver the constant flow rate and pressure
    needed for consistent and efficient coatings applications
  • Transfer & Supply: 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-ball pumps provide the flow and pressuire
    required for moving light oils and grease lubricants
  • High Pressure Cleaning: ARO Wash Pump Packages are portable and
    offer the right option for industrial cleaning
  • Advantages

  • Sheer sensitive materials: ARO 2-ball pumps minimize friction
    points to prevent fluid shear, when compared to other similar
    pumping technologies
  • Abrasive and high solids materials: 2-ball pumps minimize friction
    points and allow for smooth passages to maintain fluid consistency
  • Optional ceramic coating provides abrasive fluids like paint
    and glass-filled sealer

    4-ball piston pumps are designed to transfer high volumes of low and medium viscosity
    fluids up to 12,500 cPs with fluid delivery up to 32.8 gpm (124.0 L/min).

    Transfer & Supply: 4-ball pumps are designed to move high volumes of fluids
    in order to minimize time spent filling or emptying large containers.
    The high flow rate is a result of double-acting pumping
    (draws materials on the upstroke and downstroke) and is ideal
    for the large scale transfer of paints, chemicals, varnishes, enamels, lacquers
    and other low-to-medium viscosity fluids.


  • Corrosive materials: ARO 4-ball lower ends are constructed
    with stainless steel to maximize fluid compatbility with
    water based materials
  • Abrasize materials: A ceramic coating on the plunger
    rod and cylinder tube come standard on ARO 4-ball pumps,
    protecting from highly abrasive materials and extending the service
    life of these pumps up to 2 times.


    Designed to move medium-to-high viscosity fluids in difficult applications.
    Move medium to high viscosity fluids ranging from 15,000 cPs to more than
    1,000,000 cPs, and at delivery rates up to 12.2 gpm (46.3 L/min)
