A pneumatic solvent drum pump is designed to safely and efficiently transfer solvents (like acetone, toluene, MEK, xylene, or other aggressive chemicals) from a 55-gallon drum using compressed air. These pumps are ideal for flammable, corrosive, or volatile liquids because they eliminate spark risks and can handle harsh chemicals.
Key Features of a Pneumatic Solvent Drum Pump
✔ Explosion-Proof (ATEX/UL Certified) – Safe for flammable solvents (no electric motor).
✔ Chemical-Resistant Materials – PTFE, polypropylene, or stainless steel for corrosion resistance.
✔ Self-Priming & Dry-Run Capable – Won’t burn out if the drum runs dry.
✔ Adjustable Flow Rate – Typically 1–15 GPM (gallons per minute).
✔ Sealed Design – Prevents leaks and vapor emissions (important for OSHA/EPA compliance).
Best Types of Pneumatic Solvent Pumps
1. Air-Operated Double Diaphragm (AODD) Pump
Best for: Most solvents, including aggressive chemicals.
Materials: PTFE diaphragms, polypropylene or stainless steel body.
Example Models:
Yamada NDP-15 (PTFE wetted parts)
Flux B30 Polypropylene
Wilden Pro-Flo X
2. Drum-Specific Solvent Pump (Compact & Portable)
Best for: Direct drum mounting with a dip tube.
Example Models:
Goat Throat Pumps GT-1 (ATEX-rated for flammables)
Lutz Solvent Pump (Polypropylene or SS)
New Pig SolventSafe Pump
Buying Considerations
Chemical Compatibility – Check pump material (PTFE, PP, SS) against your solvent.
Flow Rate Needed – 2–10 GPM is common for drum dispensing.
Air Pressure – Usually 20–100 PSI (verify your compressor can supply it).
Explosion-Proof Rating – Required if handling flammable solvents (Class I, Div 1 or 2).
Drum Connection – Ensure the dip tube fits a standard 2" bung.

Safety Tips for Solvent Pumping
⚠ Use in a ventilated area (solvent fumes can be hazardous).
⚠ Ground the drum (static electricity can ignite flammable vapors).
⚠ Inspect seals & diaphragms regularly (solvents can degrade materials over time).
