If you need an electric drum pump for high-viscosity fluids (such as heavy paints, adhesives, oils, or syrups), you’ll need a pump designed to handle thicker materials without clogging or overheating. Here’s what to look for and some top recommendations:
✔ High-Torque Motor – Handles thick fluids without stalling.
✔ Positive Displacement Design – Gear, piston, or progressive cavity pumps work best (avoid centrifugal pumps).
✔ Heavy-Duty Construction – Stainless steel or hardened internals resist wear.
✔ Heating Options (Optional) – Some pumps have heated tubes/jackets to keep fluids flowing.
✔ Adjustable Flow Control – For precise dispensing.
✔ Explosion-Proof Options (if needed) – For flammable materials (ATEX/UL certified).
Ideal for oils, resins, adhesives, and paints.
Handles viscosities up to 100,000 cP+.
Examples:
Lutz B45 Gear Pump (stainless steel, up to 1,000,000 cP)
Viking Pump Internal Gear Pump (for heavy oils/chemicals)
Smooth flow for shear-sensitive fluids (silicones, sealants, food products).
Works with extremely thick pastes (500,000 cP+).
Examples:
Seepex BT Series (food-grade options available)
Moyno 2000 Series (for wastewater, adhesives, etc.)
High pressure for fill/finishing applications.
Good for sealants, lubricants, and viscous paints.
Example:
Graco Husky Drum Pump (for paints/coatings)
Gentle pumping for high-viscosity fluids with solids.
Used in food, pharmaceuticals, and chemicals.
Example:
Alfa Laval Rotary Lobe Pump
| Fluid Type | Recommended Pump Type | Example Models |
|---|---|---|
| Heavy Paints/Resins | Gear Pump | Lutz B45, Viking Pump |
| Adhesives/Sealants | Progressive Cavity or Piston | Seepex BT, Graco Husky |
| Oils/Greases | Internal Gear Pump | Viking Pump, Yamada Electric |
| Food/Cosmetics | Sanitary Lobe Pump | Alfa Laval, Waukesha Cherry-Burrell |
Viscosity Range – Check cP (centipoise) rating.
Material Compatibility – Stainless steel for chemicals, PTFE seals for solvents.
Flow Rate Needed – From 1 GPM (slow) to 50+ GPM (industrial).
Power Supply – 110V/220V or battery-operated.
Explosion-Proofing – Required for solvents/flammables (look for ATEX/UL).
