This 1/2" air operated double diaphragm pump delivers reliable performance with maximum discharge pressure of 100 PSI and flow capacity of 15 GPM. Constructed from durable aluminum alloy, it provides explosion-proof operation ideal for industrial applications.

• Self-priming capability with idling and submersion operation
• Stall-free, ice-free zero leak performance
• Epoxy-coated air section for tough environmental conditions
• Low shear force preserves material structure integrity
• Modular air valve design for low pulsation and smooth operation
• Explosion-proof - safe for flammable and hazardous environments
• No electricity required - operates on compressed air only
• Handles corrosive, volatile, flammable, and poisonous fluids
• Stepless adjustment of delivery lift and flow via pneumatic valve

This advanced diaphragm pump uses compressed air as a power source and features three-way air pilot valve technology for no dead stop operation and faster reversing. Widely used in wastewater treatment, chemical processing, petrochemical industries, painting, ceramics, environmental protection, and printing/dyeing operations. Handles various corrosive, volatile, flammable, poisonous fluids with particles and high viscosity.

Ideal for spraying paint, cleaning roofs, and anti-static spraying on conveyors and bottles. The pump's durability and consistent volume output make it perfect for dispensing cleaning chemicals, paints, and other fluids at a constant rate when combined with an air compressor.
