If you're looking for a hand-operated drum pump siphon designed for polyethylene (HDPE) 55-gallon drums, here are the best options and key considerations:
Polyethylene (HDPE) drums typically have 2" NPT or 3/4" bung openings, so ensure the pump fits securely. Since HDPE is non-conductive, static electricity buildup is a risk when transferring flammable liquids—opt for grounding-safe models.
Justrite 7250120 Manual Drum Pump
Material: Steel with polypropylene components
Flow Rate: ~3 GPM
Hose Length: 4 ft
Fits: 2" NPT bungs
Best For: Diesel, kerosene, oils
Why? Durable, chemical-resistant, and safe for HDPE drums.
Tera Pump TRH-025 Hand Siphon Pump
Material: Aluminum & thermoplastic
Flow Rate: ~5 GPM
Hose Length: 5 ft
Fits: 3/4" & 2" bungs

Why? Lightweight, corrosion-proof, and includes a grounding wire.
Lutz HDP-3 Poly Drum Pump
Material: Polypropylene (chemical-resistant)
Flow Rate: ~2 GPM
Hose Length: 3 ft
Fits: 2" NPT
Best For: Acids, bleach, ag chemicals (non-flammable)
Why? Affordable, inert to most chemicals, but not for fuels (static risk).
Fill-Rite FR1610 Hand Crank Pump

Flow Rate: ~6 GPM
Hose Length: 6 ft
Fits: 2" NPT
Best For: High-viscosity oils, diesel
Why? Heavy-duty, self-priming, and long hose.
✔ Bung Compatibility – Most HDPE drums use 2" NPT (some have 3/4").
✔ Static Safety – For fuels, choose pumps with grounding clamps.
✔ Chemical Resistance – Polypropylene or aluminum pumps resist corrosion.
✔ Self-Priming – Helps start flow without manual suction.
| Type | Pros | Cons |
|---|---|---|
| Siphon Pump (e.g., Tera TRH-025) | Lightweight, no moving parts, cheaper | Slower flow, requires priming |
| Hand Crank Pump (e.g., Fill-Rite FR1610) | Faster, self-priming, durable | Heavier, more expensive |
⚠ Ground the Drum – Use a grounding strap to prevent static sparks when pumping flammables.
⚠ Avoid PVC Hoses – Can degrade with fuels; use UL-listed fuel hose instead.
⚠ Check Compatibility – Some chemicals (e.g., strong oxidizers) may degrade HDPE.
