Overview

ARO metallic diaphragm pumps achieve flow rates of up to 1041 litres/minute and offer a wide array of material and porting configurations. These pumps are often used for transfer, filling, recirculation and batching in Ceramic, Paint, Oil and Gas, Chemical and Petrochemical markets.

Features

The Ultimate in heavy duty pump design.
Up to 4 times the life of traditional diaphragm pumps due to the EXP’s new convoluted diaphragm design.
Efficiency – Simul-Shift™ valve provides ultra-positive, reliable shift signal
Reliability – ARO’s patented ‘Unbalanced’ air valve ensures no-stall operation
Versatility – Broad range in materials of construction for optimum fluid compatibility
Environmentally Sound -Bolted construction for leak-free fluid handling and ribless fluid caps to eliminate cracking
Serviceability – Easier service through modular design
