Ask A Question

Description & Features

Manufactured by Ingersoll Rand Aro, this 1/2 in. diaphragm pump is built for reliable fluid transfer across a range of industrial fluid handling applications. Diaphragm pumps of this type are well suited for handling viscous, abrasive, or chemically aggressive fluids where centrifugal or gear-style pumps may not be appropriate.

The ARO Diaphragm Pump 1/2 carries the trusted engineering behind the Aro product line, making it a practical choice for maintenance, production, and process environments requiring consistent, leak-conscious fluid movement. Air-operated double diaphragm (AODD) designs in this class are commonly used in chemical processing, paint and coatings transfer, wastewater handling, and general industrial fluid management.

Is this here ARO pump alright to use with just about any fluid?
Answer by: Customer Support on Oct 3, 2025, 6:44 AM
As a general purpose pump, it should work in many applications. However, always ensure the fluid is compatible with the pump's materials.
Question by: Roy C on Nov 30, 2025, 8:01 PM
what brand makes this pump, and is it the same as Ingersoll Rand?
Answer by: Customer Support on Dec 2, 2025, 7:48 AM
ARO is the brand name on the pump itself, and it falls under the Ingersoll Rand family. The two names are tied together, so when you see either one listed, you're looking at the same manufacturer behind the product.
