AF0402M Series 4-Ball Piston Pump

  • 2:1 Ratio
  • Max Flow: 21.3 GPM (80.6 LPM)
  • Max Fluid Pressure: 312 psi

Simply Versatile

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.
