Lubricant drum pumps

Lubricant Drum Pumps – Selection Guide

Lubricant drum pumps are designed to efficiently transfer oils, greases, and other viscous lubricants from drums, barrels, or IBCs. They must handle varying viscosities (from light oils to heavy greases) while preventing leaks, contamination, and pump wear.


Types of Lubricant Drum Pumps

1. Manual (Hand-Operated) Lubricant Pumps

  • Best for: Occasional use, low-budget applications, or hazardous areas where electricity is unsafe.

  • Design: Rotary crank or lever-action mechanism.

  • Materials: Steel, aluminum, or polypropylene.

  • Examples:

    • Rotary hand pumps (for light to medium oils).

    • Piston pumps (for thicker greases).

2. Electric Lubricant Drum Pumps

  • Best for: Frequent, high-volume transfers in workshops or factories.

  • Motor Types:

    • Gear pumps (for medium-viscosity oils).

    • Vane pumps (for higher-pressure applications).

    • Positive displacement pumps (for heavy greases).

  • Features:

    • Adjustable flow rate.

    • Explosion-proof (ATEX) options for flammable oils.

3. Pneumatic (Air-Powered) Lubricant Pumps

  • Best for: Hazardous environments (flammable oils, explosive atmospheres).

  • Advantages:

    • No electricity = safer for fuel and solvent transfer.

    • Handles high-viscosity fluids well.

4. Battery-Operated Lubricant Pumps

  • Best for: Mobile lubrication (e.g., field maintenance, remote sites).

  • Example: 12V/24V DC oil transfer pumps.

5. Drum Pumps with Agitators (for Settled Greases & Additives)

  • Best for: Semi-fluid greases, gear oils with suspended solids.

  • How it works: Rotating blade keeps lubricant homogeneous during pumping.


Key Features to Consider

✔ Viscosity Range – Light oil (ISO 10-100) vs. heavy grease (NLGI 2-3).
✔ Material Compatibility –

  • Stainless steel (corrosion-resistant for synthetic lubes).

  • Aluminum (lightweight for general oils).

  • PTFE seals (for aggressive chemicals).
    ✔ Flow Rate – Typically 1-20 GPM (varies by pump type).
    ✔ Hose & Nozzle Options – Flexible hoses, grease gun adapters.
    ✔ Safety Certifications – ATEX for flammable oils, OSHA compliance.


Top Applications

  • Engine & gear oil transfer (automotive, marine, industrial).

  • Grease dispensing (NLGI 0-3 consistency).

  • Hydraulic fluid transfer.

  • Food-grade lubricants (USDA/FDA-approved pumps).


Recommended Models by Viscosity

Maintenance Tips

  • Clean after use (prevents clogging in grease pumps).

  • Check seals regularly (prevents leaks).

  • Use filters (for oils with debris).
