High-Flow Air Drum Pump

This air-operated drum pump delivers fluid at up to 4.76 gallons per minute and develops a maximum discharge pressure of 750 psi. It uses a 5:1 pressure ratio to move liquids from standard drums and totes. The unit is self-priming and includes a suction tube and bung adapter for immediate installation.

Suited for viscous fluid transfer.

The pump handles viscosities up to 1,750 cps, making it appropriate for oils, lubricants and similar fluids in maintenance or production settings. It requires a compressed air supply regulated to 150 psi maximum. Buyers needing a pump for water-thin chemicals, food-grade sanitary service, or electrically driven operation should look at other pump types.

5:1 pressure ratio defines output capability

The fixed 5:1 ratio means discharge pressure scales directly with the regulated air input; at the 150 psi air limit the pump reaches its rated 750 psi. This single specification determines whether the pump can overcome your system back-pressure and deliver the required flow rate.

Questions about this item

How loud is the 5:1 air drum pump when it runs continuously at 150 psi?

The pump is air-driven, so its noise level depends on the compressor supplying the 150 psi maximum air pressure rather than the pump itself.

What existing air supply and fittings do I need to operate the 4.76 gpm drum pump?

You need a compressed-air source capable of 150 psi, a 1 3/8 in air outlet connection, and the included bung adapter and suction tube for drum mounting.

Will the 750 psi discharge pressure damage older steel drums or fittings I already use?

The pump delivers up to 750 psi at the FNPT discharge connection, so verify that your existing drums, hoses and fittings are rated for that pressure before connecting them.
