If you need a plastic drum pump for transferring acids and alkalis, you’ll need a chemically resistant pump that can withstand corrosive liquids. Here’s a detailed guide to help you choose the right one:
Key Considerations for Acid/Alkali-Resistant Drum Pumps
Material Compatibility
Polypropylene (PP) – Good for most acids (e.g., sulfuric, hydrochloric) and mild alkalis.
PVDF (Kynar®) – Superior chemical resistance, ideal for strong acids (e.g., nitric, hydrofluoric) and aggressive solvents.
PTFE (Teflon®) – Best for highly corrosive chemicals but more expensive.
Avoid PVC or nylon for strong acids/alkalis.
Seals & Gaskets
Viton® (FKM) – Resistant to many acids and some alkalis.
EPDM – Better for alkalis but not strong acids.
PTFE/Teflon seals – Best for extreme chemical resistance.
Pump Type
Manual Rotary Pumps – Safe for flammable chemicals (no spark risk).
Electric Pumps – Must be explosion-proof if used with volatile chemicals.
Air-Operated (Pneumatic) Pumps – Good for harsh environments.
Recommended Plastic Drum Pumps for Acids & Alkalis

Flow rate: ~2 GPM.
2. FLUX PFA Lined Electric Pump (For Highly Corrosive Acids)
Best for: Nitric acid, hydrofluoric acid, aggressive solvents.
Features:
PFA (Teflon-like) lining, PTFE seals.
Explosion-proof motor option.
Flow rate: ~5-10 GPM.
Brands: FLUX, Lutz, Debem.
3. Kynar (PVDF) Drum Pump (Manual or Electric)
Best for: Strong acids, bromine, chlorine, oxidizers.
Features:
PVDF body, PTFE seals.
Longer lifespan than PP in harsh conditions.
Brands: March Pump, Fill-Rite.
4. GOAT Throat Drum Pump (Heavy-Duty Chemical Transfer)
Best for: Sodium hydroxide (lye), phosphoric acid.
Features:
PP or PVDF options.
Removable hose for easy cleaning.
Safety Tips When Pumping Acids/Alkalis
✔ Always check chemical compatibility charts before use.
✔ Wear gloves (nitrile/neoprene) and goggles.
✔ Ensure proper ventilation (some acids release fumes).
✔ Store the pump rinsed and dry after use.
