ARO 4-Ball Piston Pumps

Applications advantages of 4-balls:

• 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 material 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. 

Another common application: circulating fluid from the original container to the point of use, and then back.

Materials advantages of 4-balls:

• Corrosive materials: ARO® 4-ball lower ends are constructed with stainless steel to maximize fluid compatibility with water based materials.
• Abrasive 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 parts up to 2x.
