4-ball Piston Pumps & Packages 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), depending on the application.
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.
