ARO Metallic Pumps
The ARO® range of diaphragm pumps offers many materials of construction compatible for the chemical industry:
Our metallic offering consists of aluminium, cast iron, stainless steel and hastelloy.
Metallic Model Overview
All 1/2" - 3" Metallic PD pumps are now upgradeable!
PD pumps are manufactured such that solenoid operation, flow monitoring and leak detection functionality can be
added at a later date. As your processes mature, this capability allows you to enhance manually operated processes to
incorporate additional control and monitoring capabilities. Simply remove two plugs and replace with a proximity sensor
and (or) leak detector. Call ARO® Technical Service to learn more. Once upgraded, these components can also be integrated with the ARO® controller for seamless integration.
