ARO pneumatic piston pumps can help increase plant productivity by providing quick container change-over, operator convenience, a cleaner working environment, increased material savings and minimized downtime. Let ARO piston pumps increase your plant productivity, not just once but day after day.
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 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 (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.
Additional equipment is sometimes needed to keep an extrusion or finishing pump primed. Follower plates, lifts and rams assist the flow of material into the pump inlet. Lifts can be used for fluids with viscosities up to 200,000 cPs. Rams are needed for fluids with higher viscosities. If a fluid is stringy, a ram may be needed for fluids with viscosities as low as 60,000 cPs. Carts allow for mobility when engaging in finishing applications where pump location counts.
