Overview
About the AOD 400 PF Non-Metallic
The AOD 400 PP/PVDF Air Operated Double Diaphragm Pump is a heavy-duty, air-driven diaphragm pump suitable for handling corrosive, acidic, and chemically aggressive fluids. Its PP and PVDF construction provides excellent chemical resistance, making it ideal for industries where metallic pumps may fail due to corrosion.
This pump operates without an electric motor, making it safer for wet, hazardous, and chemical environments. The Teflon diaphragm offers superior compatibility with aggressive chemicals, while the Neoprene diaphragm is suitable for general-purpose industrial liquids. The Teflon NRV balls ensure smooth non-return valve operation and long service life.
Sando AOD 400 is widely used in chemical processing, wastewater treatment, electroplating, pharmaceuticals, acids, alkalis, and liquid transfer applications where reliability, safety, and corrosion resistance are important.

Selection Guide
AODD vs. Centrifugal Pumps
-
1
Use non-metallic AODD pumps when corrosion resistance, self-priming, and dry-run tolerance matter.
-
2
Use centrifugal pumps for clean, non-abrasive liquid movement at stable flow conditions.
-
3
AODD pumps handle changing viscosity and entrained solids better than many centrifugal selections.
For selection, share flow rate, discharge pressure or head, viscosity, temperature, solids content and installation conditions — our engineers will recommend the right aodd non-metallic configuration.
