ARO Hydraulic Driven Four Ball Piston Pumps - Four-ball piston pumps are perfect for higher volume and recirculation applications involving low viscosity fluids (0 – 5,000 cPs). ARO four-ball pumps are constructed of stainless steel and are available in a wide range of packing materials to maximize fluid compatibility. Additionally, the plunger rod and cylinder tube are ceramic coated to fight the effects of abrasion and scoring.
