Two-Ball Pumps

Two-ball piston pumps are the most versatile type of piston pump capable of transferring a wide range of low to medium viscosity fluids (0 - 25,000 cPs). ARO two-ball pumps can provide up to 6000 psi fluid pressure and are available in a wide range of packing options to accommodate an array of chemical compatibilities.
   
Four-Ball 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.
   
Chop-Check Pumps

Chop-check (extrusion) pumps are most frequently utilized in the most difficult of applications, as they are designed to move medium to high viscosity fluids (15,000 to 1,000,000+ cPs) such as caulking, heavy lubricants, mastics, sealers, and inks. ARO extrusion pumps are available in a wide variety of materials of construction to accommodate your pumping needs.
