Drum Pump for 55-Gallon Drums

The Finish Thompson DPFP024 is an air-operated drum pump designed to empty 55-gallon drums. It suits industrial maintenance teams and plant operators who need a basic pump package with a discharge hose for transferring fluids from standard containers.

Build Integration and Air Requirements

The pump connects to a compressed-air supply at 80 psi through a 1/4-inch MNPT inlet and discharges through a 1-inch hose barb. It frees up manual labour by delivering up to 22 gallons per minute for low-viscosity fluids and 17 gallons per minute for oil, handling viscosities up to 330 cps.

Thermals, Noise and Power Draw

Operating solely on compressed air at a fixed 80 psi, the unit produces a maximum head of 38 feet and 16.5 psi discharge pressure. Fluid temperature must stay above 35 degrees Fahrenheit. No electric motor is present, so electrical power draw and motor noise are not factors.

Highlights

  • Air-powered operation eliminates electric motor hazards
  • 22 GPM maximum flow rate for rapid drum emptying
  • Handles fluids up to 330 cps viscosity
  • 38 ft maximum head pressure for elevated dispensing
  • 1/4 in MNPT air inlet connects to standard shop air

Questions about this item

What maximum viscosity in cps can this pump handle before flow drops off?

The pump is rated for fluids up to 330 cps viscosity; thicker liquids will reduce the 22 gpm maximum flow.

How much compressed air at 80 psi does the 1/2 HP motor consume during continuous operation?

The unit requires a steady 80 psi air supply at the 1/4 in MNPT inlet; sustained running will demand constant compressor capacity.

Which drum size and discharge hose connection are needed to install this package?

It fits a 55 gal drum and includes a discharge hose with a 1 in ID hose barb outlet.
