Drum pump for 55-gallon containers

This air-operated drum pump delivers up to 22 GPM for transferring fluids from standard 55-gallon drums. It handles viscosities up to 330 cps with a maximum head of 38 feet. The unit weighs 19.35 and connects via a 1-inch hose barb discharge.

Upgrade from manual or low-flow pumps

Replaces hand pumps or slower electric units when moving higher volumes of oil or similar fluids. The jump is worth it when flow rates above 17 GPM for oil are needed and compressed air at 80 PSI is available. Maximum discharge pressure reaches 16.5 PSI.

Check air supply and fluid compatibility

Verify your compressor can maintain a steady 80 PSI at the 1/4-inch MNPT inlet. Confirm the fluid temperature stays above -20 degrees F and viscosity does not exceed 330 cps. Ensure the 1-inch ID discharge hose fits your existing plumbing.

Questions about this item

What discharge connection size does the 1 in ID hose barb need on my container?

The pump uses a 1 in ID hose barb with a 1 5/16 in OD tube outlet for discharge.

How do I connect the air supply to the 1/4 in MNPT inlet, and what pressure is required?

Connect a 1/4 in MNPT air line; the pump requires exactly 80 psi minimum and maximum air pressure to operate.

When should I inspect the pump if fluid viscosity reaches 330 cps or temperature drops to -20 Degrees F?

Inspect seals and the discharge hose regularly when pumping fluids at the maximum 330 cps viscosity or near the minimum -20 Degrees F temperature limit.
