Cast Iron and Stainless Steel Pump Models Expand Diaphragm Pump Portfolio

Ingersoll Rand has announced it has expanded its ARO Pro Series portfolio of diaphragm pumps by enhancing the two- and three-inch ported metallic pump models to include additional materials of construction.

Previously offered only in aluminum, the Pro Series now includes pumps in cast iron and stainless steel. ARO now offers all three materials for all port sizes of its Pro Series portfolio, making them ideal for plant maintenance, OEM applications, primary and secondary production and bulk transfer. More information on industries and applications can be found online by visiting the Fluid Technologies Productivity Park.

Like their aluminum counterparts, the new models feature patented air valve technology that eliminates pump stalling by utilizing an “unbalanced” design. By creating an optimal pressure differential, air valves do not center, even under low air inlet pressures. Unbalanced valves reduce production loss and downtime by providing better shift signals and delivering faster trip-over with more flow (172 gpm and 237 gpm, respectively for two- and three-inch models).
