American Lube 66605J-322 1/2″ DIAPHRAGM PUMP
ARO Diaphragm Pumps
Patented Air Valve – ARO's patented “unbalanced” air valve design eliminates stalling, a common occurrence in competitive pumps.
Hi-Flow – These pumps offer high-volume delivery of material even at low air pressures.
Runs Dry – ARO diaphragm pumps can run dry without any damage to the pump.
Bolted Construction – Pumps feature bolted construction to avoid the proven problems created by band clamp type pump fasteners.
Lube-Free Air Motor – ARO diaphragm pumps are pre-lubricated. They do not require an air lubricator, eliminating maintenance concerns. (The use of a lubricator is not recommended)
Variable Flow Rate – Adjusting the air pressure to the pump allows precise control over the pump's flow rate without damaging the pump.
Simple Design – Provides trouble-free operation and virtually maintenance-free performance.
