drum pump for corrosive liquids

If you need a drum pump for corrosive liquids, you’ll need a pump made from chemically resistant materials like polypropylene (PP), PTFE (Teflon), PVDF, or stainless steel (316 SS). Here’s what to look for and some recommended options:

Key Features for Corrosive Liquids:

1. Material Compatibility

• Polypropylene (PP) – Good for acids (e.g., sulfuric, hydrochloric) and solvents.

• PTFE (Teflon) – Best for highly aggressive chemicals (e.g., nitric acid, bromine).

• PVDF – Stronger than PP, handles harsh solvents and halogens.

• Stainless Steel (316 SS) – For some acids (e.g., nitric), but not for chlorides.

2. Seals & Gaskets

• Viton (FKM), EPDM, or PTFE seals for chemical resistance.

3. Type of Pump

• Manual Rotary Pump – Affordable, no power needed.

• Electric Pump – Faster, but must be explosion-proof if handling flammable chemicals.

Recommended Drum Pumps for Corrosive Liquids:

1. Manual Rotary Pumps (Budget-Friendly)

• Lutz Jesco Polypropylene Chemical Pump

• Material: PP body, PTFE seals

• Handles: Acids, solvents, bleach, etc.

• Price: ~$100–$150

• Where to Buy: Amazon, Grainger, U.S. Plastic Corp.

• GoatThroat Pumps GT-1 (PTFE Lined)

• Material: PTFE internals, HDPE body

• Handles: Aggressive chemicals (e.g., HCl, HNO₃, acetone)

• Price: ~$300–$500 (high-end but ultra-resistant)

2. Electric Pumps (Faster Transfer)

• Fill-Rite FR Series (PP or PVDF)

• Material: Polypropylene or PVDF

• 12V or 120V options, explosion-proof available.

• Price: ~$200–$600

• Tuthill D Series (316 SS or PVDF)

• Good for industrial chemical transfer.

• Price: ~$500+

Harbor Freight Alternative?

Harbor Freight’s polypropylene drum pump (if available) might work for mild chemicals, but for highly corrosive liquids, a specialty chemical pump (like Lutz Jesco or GoatThroat) is safer.
