3 Inch AODD Pump Assembly Ductile Iron PTFE Membrane - 270 GPM Flow Rate, 120 PSI Working Pressure
Industrial-grade 3-inch air-operated double diaphragm pump with ductile iron construction and PTFE membrane. Features 270 GPM maximum flow rate, 120 PSI working pressure, and safe operation in flammable environments. Handles corrosive media, viscous fluids, and particle-laden liquids with multiple diaphragm material options available.
This 3-inch AODD pump assembly features a ductile iron construction with PTFE membrane, designed for demanding industrial applications requiring reliable performance in challenging environments.
- Air-powered operation eliminates heat generation and spark production, making it safe for flammable and explosive environments
- PTFE diaphragm construction enables handling of volatile chemicals and corrosive media
- Capable of pumping particle-laden liquids and handling wide viscosity ranges
- No priming required, prevents fluid foaming, and eliminates stall damage risks
