This 1/2" pneumatic aluminum diaphragm pump is engineered for efficient waste water and sewage handling applications. Featuring ARO's patented unbalanced air valve technology, it delivers reliable no-stall operation in demanding industrial environments.

• Mobility: Compact, rugged design ensures easy transportation and installation
• Efficiency: Optimized motor design delivers maximum air efficiency
• Reliability: Patented unbalanced air valve prevents stalling during operation
• Versatility: Available in aluminum, cast iron, or stainless steel for various chemical applications
• Environmental Safety: Bolted construction provides leak-free fluid handling
• Serviceability: Easy access to ball checks and fluid caps simplifies maintenance

This aluminum diaphragm pump utilizes compressed air as its power source and represents the most advanced air-operated diaphragm pump technology currently available. The three-way air pilot valve ensures real no-dead-stop operation and faster reversing. Ideal for waste water treatment, chemical processing, petrochemical operations, painting systems, ceramics manufacturing, environmental protection, printing, and dyeing applications. Capable of handling corrosive, volatile, flammable, toxic fluids with particles and high viscosity.

Air-driven double diaphragm pumps are perfect for spraying paint, cleaning roofs, and spraying conveyers/bottles for anti-static purposes. These pumps are specifically suited for these applications due to their exceptional durability and consistent volume output. When combined with an air compressor, they enable precise dispensing of cleaning chemicals, paints, and other fluids at a constant rate.
