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
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.

A piston pump motor is the driving force behind a piston pump — a type of positive displacement pump that moves fluids using a back-and-forth motion.
Your formulation hasn't changed. Your process parameters look identical. Yet one batch passes quality control with flying colors while the next gets rejected for inconsistent viscosity or trapped air bubbles. The real issue? Unstable flow during transfer and dispensing.
