Ingersoll Rand Expands ARO Pro Series Diaphragm Pump Portfolio

ThomasNet brings a news release of Ingersoll Rand. The company announced it has expanded its ARO Pro Series portfolio of diaphragm pumps by enhancing the 2- and 3-inch ported metallic pump models to include additional materials of construction.

Previously offered only in aluminum, the Pro Series now includes 2- and 3-inch ported 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 2- and 3-inch models).

"Our Pro Series pumps continue to lead the way for industrial applications where robust pump construction and reliability is required," said Oakley Roberts, global marketing manager for Ingersoll Rand. "These new models enhance our Pro Series portfolio and provide our customers with greater flexibility for their applications."

Pro Series pumps also deliver gains in energy efficiency. With bolted construction and a variety of material options, these pumps feature leak-tight integrity and excellent chemical compatibility. O-rings and U-cups prevent air leakage by providing a positive seal as the air valve shifts. Air flow stops when the fluid flow stops.

ARO Pro Series diaphragm pumps are backed by a five-year warranty on materials and workmanship. For further details on ARO Pro Series diaphragm pumps, see your local distributor, call (800) 495-0276 or visit fluids.ingersollrand.com.
