ADDITIONAL INFORMATION:
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
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
VARIETY
ARO diaphragm pumps are available in metallic and composite bodies, single and multiple-port designs, and many different ball, seat, and diaphragm configurations to suit your applications
