ARO 6661AJ-3EB-C Aluminum Polypropylene Diaphragm Pump is a Pro Series 1″ non-metallic air-operated diaphragm pump designed for efficient and reliable industrial fluid transfer. It features a lightweight aluminum center body that provides durability and structural strength while keeping the pump easy to handle. The polypropylene fluid sections offer excellent resistance to corrosion and chemical attack, ensuring long-lasting performance. It uses Santoprene ball checks for secure sealing and consistent operation with a variety of fluids. The Santoprene diaphragm adds flexibility and chemical compatibility for extended service life. With a maximum flow rate of 47 GPM, the pump delivers smooth and efficient fluid transfer. Its flange and NPT connections allow easy integration into standard piping systems. The pump handles solids up to approximately 1/8″ (3.2 mm) and supports a dry suction lift of about 15 ft (4.6 m). Overall, it is ideal for chemical processing, water treatment, and general industrial applications requiring durable and versatile pumping solutions.
