For handling gasoline, solvents, alcohol, and other flammable liquids from drums/IBCs, you need specialized pumps designed to prevent ignition risks. Here's what matters:
✔ Explosion-Proof Certification (ATEX/UL/CSA for Zone 1/Class I Div 1)
✔ Grounding Wire – Prevents static sparks
✔ Non-Sparking Materials – Aluminum, brass, or conductive plastics
✔ Sealless Design – Magnetic drive or diaphragm pumps eliminate leak points
| Type | How It Works | Max Flow | Best For |
|---|---|---|---|
| Air-Operated Diaphragm | Pneumatic power (no electricity) | 15 GPM | Gasoline, acetone in hazardous areas |
| ATEX Electric | Low-voltage DC with sealed motor | 10 GPM | Diesel, kerosene in Zone 2 areas |
| Manual Rotary | Hand-cranked, no power needed | 5 GPM | Small solvent transfers |
| Magnetic Drive | Sealless impeller design | 20 GPM | Aggressive chemicals like toluene |
For Gasoline:
Yamada NDP-20-ATEX ($1,200)
Air-powered, handles 20 GPM
ATEX Zone 1 certified
For Solvents (Acetone/Xylene):
FLUX FLEXI-FLO EX ($950)
24V DC, magnetic drive
Zero leakage design
Budget Option:
Lutz 8500-EX Manual Pump ($250)
ATEX-approved for Zone 1
2 GPM flow rate
Bonding & Grounding – Use copper straps between drum, pump, and receiving vessel
Ventilation – Never pump in confined spaces
Nozzle Selection – Conductive hoses with automatic shutoff
North America: UL 79, CSA C22.2 No. 30
Europe: ATEX Directive 2014/34/EU
Global: IECEx Certification
Warning: Never use standard AC pumps with flammables – even a small spark can cause explosions. Always verify the pump's certification matches your liquid's flash point.
