Drum & Barrel Pumps

4 products available

Drum pump and barrel pump systems move production chemicals, lubricants, and fuels safely from bulk storage containers. Designed for industrial workshops, maintenance bays, and processing plants, these transfer tools eliminate manual container tipping and reduce fluid contamination. Compel supplies industrial fluid handling equipment built for standard 55-gallon (208 L) drums, storage barrels, and chemical tanks.

Our inventory includes everything from a manual hand crank barrel pump for localized maintenance to a high-output electric drum pump for rapid bulk transfer. With configurations spanning aluminum-copper alloy assemblies for fuel service to acid-resistant screw units, you can match your pump directly to fluid viscosity and container depth. Buy from Compel for reliable stock availability, precise specification data, and dependable international shipping.

Power Source: Manual Operation vs. Electric Drive

Choosing between manual and electric drive depends on daily transfer volume, job frequency, and power availability across your facility. Manual pumps suit intermittent jobs, remote storage pads, and utility trucks where electrical connections are absent.

Electric models handle high-volume fluid transfers quickly without operator fatigue. If your facility unloads multiple barrels daily or transfers viscous oils, an electric motor maintains steady flow across long cycle times.

  • Manual rotary crank: Features a rotating handle driving internal gears. Delivers a continuous 20 to 25 L/min flow rate for fuels and lubricants.
  • Manual lever action: Uses an up-and-down stroke to lift heavier oils and general liquids cleanly through an adjustable suction tube.
  • Electric units: Feature 800 W to 1300 W motors running on 220 V supply, using screw pump mechanisms to rapidly evacuate heavy fluids.

Material Selection and Chemical Compatibility

Fluid chemistry dictates pump housing and internal component materials. Mismatched materials lead to internal seal degradation, fluid contamination, and pump seizure.

Standard aluminum alloy and aluminum-copper alloy pumps are built for non-corrosive hydrocarbons. They transfer diesel, machine lubricating oils, and light petroleum products smoothly. Never use aluminum pumps for strong acids, caustics, or reactive chemical solutions.

For corrosive liquids, select dedicated chemical barrel pumps. These units use inert structural materials designed specifically to resist medium to high concentrations of acids and alkalis without pitting or leaking.

Container Fit and Suction Tube Sizing

Most industrial liquids ship in standard 55-gallon (208 L) drums. To empty the drum completely, the suction tube must extend near the bottom without blocking the inlet against the container base.

Check the suction tube specification before ordering. Compel supplies barrel pumps with adjustable suction tubes extending up to 100 cm. Telescoping or threaded segments allow operators to adjust the draw depth for shallower barrels or odd-sized storage vats, ensuring maximum fluid recovery.

Buying guide

Choosing Drum & Barrel Pumps

When should I choose a rotary drum pump over a lever-action pump?
Choose a rotary drum pump when you need smooth, continuous fluid delivery for fuel or light oils. Rotary gear models generate steady discharge rates between 20 and 25 L/min with continuous turning. Lever-action pumps work better for high-viscosity oils and precision dispensing where you control output stroke by stroke.
Will these pumps mount directly to a standard 55-gallon (208 L) drum?
Yes. Most units in our catalog feature drum and barrel bung mounts sized for standard 55-gallon (208 L) containers. They include rigid or adjustable suction tubes reaching depths up to 100 cm to reach the bottom of standard industrial drums.
Can I pump acidic or alkaline solutions with an aluminum alloy barrel pump?
No. Aluminum and aluminum-copper alloys corrode rapidly when exposed to acidic or alkaline media. For medium to high concentration acids and alkalis, select a specialized electric drum pump listed with acid-alkali resistance and inert wet components.
What flow rate does an industrial manual barrel pump provide?
A standard manual rotary drum pump delivers between 20 and 25 L/min under typical operating conditions. Actual flow depends on fluid viscosity, ambient temperature, and manual cranking speed. For higher volume requirements, step up to a 220 V electric model rated from 800 W to 1300 W.
Can electric drum pumps transfer flammable fluids like gasoline?
Only use a pump for gasoline if the product specification explicitly lists gasoline compatibility. Standard 220 V electric units in this category are intended for diesel, machine oils, and non-corrosive liquids. For volatile fuels, verify the specific product listing and datasheet for ignition protection before use.
