✔ Explosion-proof – No electricity = no spark risk (ATEX/IECEx certified)
✔ High viscosity handling – Typically up to 50,000–100,000 cP (gear/diaphragm models)
✔ Materials – Aluminum, stainless steel (SS316), or PTFE-lined for chemical resistance
✔ Flow rates – 10–40 LPM (varies by model)
✔ Self-priming – Can run dry briefly without damage
| Model | Brand | Max Viscosity | Flow Rate | Best For |
|---|---|---|---|---|
| Yamada NDP-20 | Yamada | 50,000 cP | 20 LPM | Hydraulic oils, solvents |
| FLUX FPC-30 | FLUX | 30,000 cP | 30 LPM | Diesel, lubricants |
| Aro 233-A | Ingersoll Rand | 10,000 cP | 15 LPM | Light oils, kerosene |
| Wilden P1 | Wilden | 100,000 cP | 40 LPM | Gear oils, thick greases |
| Finish Thompson Sani-Force Air | FT | 20,000 cP | 25 LPM | Food-grade oils (SS316) |
Consider these factors:
Oil type – Hydraulic, gear, diesel, edible?
Viscosity – Light (10–100 cP) or heavy (10,000+ cP)?
Drum size – Standard 200L (55-gallon) or smaller?
Air supply – Requires 4–7 CFM @ 6–8 bar (check compressor capacity)
Material – Aluminum (general use), SS316 (corrosive oils), PTFE (solvents)
Safer – No sparks, no overheating
More durable – Fewer moving parts = less maintenance
Better for thick oils – Higher torque handles viscosity easily
Works in wet/dirty environments – No electrical components to fail
✔ Use an air filter-regulator (prevents moisture/dirt buildup)
✔ Lubricate with pneumatic tool oil (extends pump life)
✔ Store with pump head elevated (prevents oil residue hardening)
✔ Inspect diaphragms/gears annually (replace if worn)
Drum adapter kit – Secures pump to bung opening
Oil-resistant discharge hose – 1–2 meters with shutoff nozzle
Pneumatic moisture trap – Protects pump from water in air lines
Pressure gauge – Monitors air input (optimizes flow)
Pro Tip: For used motor oil or gritty fluids, choose a diaphragm pump (like Wilden P1)—it handles abrasives better than gear pumps.
