PA3120-03: Self-Priming, Corrosion-Resistant, Oil-Free Purity! Pneumatic Double Diaphragm Pump Empowers Complex Fluid Transfer

In industries such as chemical, environmental protection, and food processing, which require handling high-viscosity fluids, fluids containing solid particles, or highly corrosive media, traditional pumps are prone to wear, corrosion, or contamination. The PA3120-03 Pneumatic Double Diaphragm Pump (AODD Pump), with its seal-less design, strong self-priming capability, and ability to run dry without damage, offers an ideal solution for transferring complex fluids.​​Core Product Advantages​​​​Leak-proof Self-Priming Capability​​No need for priming; self-priming lift can reach over 5 meters. The seal-less design completely eliminates leakage risks, ensuring safety and environmental friendliness.​​Corrosion and Abrasion Resistance​​Wetted components (diaphragms, ball valves, pump body) can be constructed from materials like Polypropylene (PP), Polyvinylidene Fluoride (PVDF), or Stainless Steel (SUS316), providing compatibility with various corrosive and abrasive media.​​Dry-Running Capability Without Damage​​Contains no mechanical transmission parts, allowing for extended dry running without pump damage. Particularly suitable for applications with frequent starts/stops or unstable media supply.​​Adjustable Flow, Easy Control​​Output flow and pressure (max. pressure typically ≤ 0.8 MPa) can be steplessly adjusted by regulating the inlet air pressure or flow, offering simple and flexible operation.​​Portable and Intrinsically Safe​​Operates entirely on compressed air, requires no electric motor, and produces no sparks, making it intrinsically explosion-proof. Can be used directly in hazardous areas.​​Typical Application Scenarios​​​​Chemical Industry:​​ Transferring paints, solvents, acids, alkalis, and other corrosive media.​​Environmental / Water Treatment:​​ Handling sludge, flocculants, wastewater, and other fluids containing solids.​​Food & Pharmaceutical:​​ Transferring jam, emulsions, pharmaceutical liquids, and other sanitary-grade media (requires food-grade materials).​​Mining & Ceramics:​​ Pumping mineral slurries, glazes, ceramic slips, and other highly abrasive media.​​Technical Parameters (Typical Values)​​​​Port Size:​​ DN25 / 1 inch (03 may indicate size code)​​Max Flow Rate:​​ Up to 200 L/min (dependent on air pressure and media)​​Max Air Pressure:​​ 0.8 MPa​​Self-Priming Lift:​​ 5 meters (water)​​Temperature Range:​​ -20°C ~ +100°C (dependent on diaphragm material)​​Summary​​The PA3120-03 Diaphragm Pump is a ​​”Versatile Performer”​​ for complex fluid transfer. Its powerful self-priming ability, broad media compatibility, and intrinsic safety features make it the preferred choice over traditional pumps in numerous industrial sectors.​​Choosing the PA3120-03 means equipping your critical processes with a reliable, flexible, and safe core component for fluid transfer!​
