Ingersoll Rand expands ARO Pro line

Ingersoll Rand has expanded its ARO Pro Series portfolio of diaphragm pumps by adding additional construction materials to its 2 and 3 in ported metallic pump models.

Previously offered only in aluminium, the ported pump models are now also available in cast iron and stainless steel. ARO now offers all three materials for all port sizes of its Pro Series portfolio, making them suitable for plant maintenance, OEM applications, primary and secondary production and bulk transfer.

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 centre, even under low air inlet pressures. This can help 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 the 2 in and 3 in models).
