A Flux pneumatic drum pump is an air-powered pump designed for transferring liquids (including corrosive, viscous, or hazardous chemicals) from drums, barrels, or IBCs. These pumps are ideal for environments where electricity is unsafe or unavailable.
✅ Air-powered – Safe for flammable/explosive environments (ATEX certification available).
✅ Lightweight & portable – Easy to move between drums.
✅ Chemical-resistant materials – Often made of stainless steel, polypropylene, or PVDF.
✅ Adjustable flow rate – Controlled by air pressure (typically 20-90 psi).
✅ No electricity required – Reduces ignition risks.
Runs on compressed air (usually 1-10 CFM at 6-8 bar).
Often vane-type or piston-driven for efficiency.
Made from stainless steel, PP, or PVDF for chemical resistance.
Houses the rotor/stator mechanism.
Moves fluid smoothly, even high-viscosity liquids.
Extends into the drum (often telescopic or cut-to-length).
Material matches pump body (e.g., PP, SS316).
May include a shut-off valve or nozzle for controlled dispensing.
Adjustable air pressure controls flow speed.
May include a filter/lubricator (FRL unit) for clean, smooth operation.
Viton, EPDM, or PTFE seals for chemical compatibility.
Prevents leaks at connections.
Prevents backflow when the pump stops.
Secures the pump to the drum opening (standard 2" NPT or DIN bung).
✔ Chemicals – Acids, solvents, adhesives.
✔ Paints & inks – High-viscosity fluids.
✔ Food & Pharma – Hygienic transfers.
✔ Oils & fuels – Safe for flammable liquids.
Lubricate the air motor (if required) to extend lifespan.
Inspect seals & gaskets regularly for wear.
Clean after use to prevent clogging (especially with viscous fluids).
Check air supply – Low pressure reduces efficiency.
