Ingersoll Rand/ARO Piston Pumps are used in some of the toughest applications throughout industry. This broad range of pumps are used with low-to-high viscosity fluids for general transfer, fluid recirculation and extrusion. Lower ends are constructed of carbon or stainless steel, providing optimum fluid compatibility. Chrome-plating and their exclusive ultra-coating combat the wear associated with moving abrasive fluids. The six-inch stroke air motors allow operators to slow pump cycling, further extending service life. Ingersoll Rand/ARO Piston Pumps are available in ratios from 1:1-to-65:1 Models include two-ball, four-ball and chop-check (extrusion) lower ends.
