Rugged and Reliable in Harsh Conditions.
ARO diaphragm pumps are expertly engineered to go the distance, even in the harshest environment.
These pumps feature maximized flow rates with minimized pulsation and air consumption. ARO’s patented unbalanced air valve design ensures stall-free, ice-free operation. Due to their pneumatic motor, ARO’s diaphragm pumps could be used in potentially explosive areas.
ARO’s diaphragm pumps are a reliable, cost-effective choice for industrial and chemical applications. The bolted, leak-free construction eliminates cross-contamination and increases operator safety. Modular construction, reduced parts count and easy-to-use repair kits minimize repair time and cost.
These pumps are rigorously tested — far beyond typical industrial use — to ensure that your diaphragm pump is built to last.
Diaphragm Pumps Tailored to Your Application
ARO diaphragm pumps are available with many flow rates and sizes, allowing you to vary the flow outlet and discharge pressure. These pumps can run as slow as 0.26 gallons (1 liter) per minute and up to 275 gallons (1079 liters) per minute for larger pump sizes. Adjust fluid pressure up to 125 p.si. (8.6 bar) by using an air filter/regulator and a needle valve.”
