What is an aro pump?

ARO started its business in 1930, began selling pumps in the 1950s and was acquired by Ingersoll-Rand in 1990. ARO pump factory has passed ISO9001 and European CE certification, providing high quality products and services.

Ingersoll-rand, ARO pump’s main advantage lies in the key components of pneumatic pump — pneumatic motor, with a number of patents, no dead point, no stall motor, D valve structure and so on, these patents ensure that ARO pneumatic diaphragm pump is in an absolute position in motor technology.
