ARO 4-Ball Piston Pumps

High-volume fluid handling is essential for maintaining production efficiency and throughput. When operations require moving large quantities of paints, chemicals, coatings, or other low- to medium-viscosity materials, having a reliable pumping solution ensures consistent performance and keeps production schedules on track.

Built for High-Volume Applications

ARO 4-ball piston pumps support high-volume operations with dependable, continuous performance. Designed for materials up to 12,500 cPs and flows up to 32.8 gpm, they deliver smooth, consistent output on every stroke. Robust material options allow these pumps to handle diverse fluids while helping keep production predictable and efficient.

Where 4-Ball Pumps Deliver Best

• Transfer & Supply: Move high volumes of paints, chemicals, varnishes, enamels, and lacquers efficiently. Flow rates up to 32.8 gpm minimize time spent filling or emptying large containers, keeping production lines supplied without delays.
• Recirculation Systems: Circulate fluids continuously from original containers to application points and back, maintaining material consistency throughout production while reducing waste.
• Bulk Material Handling: Transfer large quantities of coatings and industrial fluids between storage tanks, supply vessels, and production equipment.
• Feeding Process Equipment: Provide steady, reliable material supply to mixers, reactors, spray systems, and other downstream equipment requiring continuous flow.

What Sets These Pumps Apart

• High-Flow Double-Acting Technology
  Four-ball valve design combined with double-acting operation creates fluid movement on both pump strokes. This delivers nearly twice the flow rate compared to single-acting designs, maximizing throughput for time-sensitive operations where transfer speed directly impacts productivity.
• Material Compatibility for Industrial Fluids
  Stainless steel lower end construction handles water-based and corrosive formulations. When your process involves abrasive materials, standard ceramic coating on plunger rods and cylinder tubes provides enhanced wear resistance, extending component durability.
• Pneumatic and Hydraulic Options
  Available with pneumatic air motors or hydraulic motor configurations, providing flexibility to integrate into your existing facility infrastructure without requiring new power source installations. 
• Simplified Maintenance Approach
  Universal valve block design means serviceable components work across different motor sizes, reducing spare parts inventory. Interchangeable parts speed up maintenance procedures and minimize equipment downtime when service is needed.
• Support Throughout Your Operation
  Our application specialists work with you to determine the right pump specifications based on your fluid properties, desired flow rates, and operating pressures. From selection to installation and ongoing operation, we provide guidance to help optimize your fluid handling processes.
