ARO diaphragm pumps are expertly engineered to go the distance, even in the harshest environment. Their pumps feature maximized flow rates with minimized pulsation and air consumption. Patented unbalanced air valve design ensures stall-free, ice-free operation. Due to their pneumatic motor, diaphragm pumps could be used in potentially explosive areas. 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. ARO diaphragm pumps are a reliable, cost-effective choice for industrial and chemical applications.
