Ingersoll Rand, ARO has been a leading developer and manufacturer of high-performance hydraulic piston pumps for more than 70 years. ARO® piston pumps are available in different styles, including 2-ball, 4-ball and chop-check piston pumps, providing exceptional performance and reliability. When choosing the right model of piston pump for your application, you’ll need to consider the type of fluid you’re handling, its viscosity or thickness, the required flow rate and required output pressure. For a piston pump, water handling is easy, but other materials require special consideration. If you need a high pressure piston pump, there are solutions for that as well.  Read more...

ARO 2-Ball Piston Pumps

The ARO 2-ball piston pumps are made for consistent, uniform fluid delivery. These pumps are highly versatile. They can handle simple fluid transfer to extrusion of low to medium viscosity materials up to 100,000 cPs, with fluid delivery up to 18.1 GPM. The 2-ball pump design provides a constant flow rate and pressure that’s ideal for applying coatings. These pumps offer the right flow and pressure to move light oils and greases. They can also be used for high pressure cleaning. The design minimizes friction points, preventing fluid shear and allowing for fluid consistency.

ARO 4-Ball Piston Pumps

ARO 4-ball piston pumps are designed for low and medium viscosity fluids up to 12,500 cPs with fluid delivery up to 32.8 GPM. These 4-ball pumps can process higher fluid volumes, which minimizes the time spent filling and emptying containers. The double-acting pumps, drawing material on both the upstroke and downstroke, allow for a higher flow rate. Large scale operations can use 4-ball piston pumps to transfer chemicals, paints and similar types of liquids. These pumps are frequently used to circulate fluids from one container to where it is used and back again. The lower ends of ARO 4-ball piston pumps are made with stainless steel for greater compatibility of fluids with water-based materials. The cylinder tube and plunger rod have a ceramic coating to protect from abrasive materials and extend service life.

ARO Chop-Check Piston Pumps

For moving medium to high viscosity fluids in challenging applications, choose ARO’s Chop-Check pumps. These heavy-duty pumps can move fluids that range from 15,000 cPS to more than 1,000,000 cPs, with a delivery rate of up to 12.2 GPM. Sample applications include the delivery of sealants, caulking, heavy lubricants and adhesives, with the desired flow rate and pressure. Certain models can efficiently transfer inks and heavy greases. These chop-check pumps are designed to handle stringy materials and, with certain options, tacky materials.
