200 Litre Drum Pump Maintenance and Selection

For safe, efficient transfer of liquids from standard 200L (55-gallon) drums, here’s what you need to know:

1. Pump Types for 200L Drums

2. Key Selection Factors

A. Material Compatibility

• Polypropylene (PP): Budget option for mild chemicals

• Stainless Steel (316SS): Corrosive/sterile applications

• PVDF/PTFE: Aggressive solvents (acetone, MEK)

B. Viscosity Handling

• Low (<1,000 cP): Centrifugal pumps

• Medium (1,000-50,000 cP): Gear pumps

• High (>50,000 cP): Diaphragm/piston pumps

C. Safety Features
✔ ATEX certification (flammable liquids)
✔ Grounding wire (static protection)
✔ Drip-proof motor (IP54+)

3. Top 200L Drum Pump Recommendations

A. Best Manual Option

• Lutz Jesco 8500

• Materials: PP/SS316

• Flow: 12 LPM

• Ideal for: Acids, solvents, oils

B. Best Electric Option

• FLUX FLEXI-FLO 25

• Materials: PVDF/SS316

• Flow: 25 LPM

• Features: ATEX, self-priming

C. Best Pneumatic Option

• Yamada NDP-15

• Materials: Aluminum/PTFE

• Flow: 18 LPM

• Ideal for: Paint, adhesives

D. Best Battery Option

• Koshin KTL-20

• Materials: PP/SS

• Flow: 20 LPM

• Runtime: 4-6 hrs per charge

4. Maintenance Tips

1. Always prime before use (especially for viscous liquids)

2. Flush with clean solvent after chemical transfers

3. Store vertically to prevent shaft bending

4. Replace seals annually (Viton®/EPDM)

5. Accessories to Consider

• Drum adapters (for secure bung mounting)

• Flexible discharge hoses (1-2m length)

• Nozzle kits (for precise pouring)

• Filter attachments (for particle-laden fluids)

Pro Tip: For 200L drums of high-viscosity fluids (>10,000 cP), choose a pump with gear or piston mechanism – centrifugal models will struggle.
