What Is a Drum Pump?
A drum pump, also called a barrel pump, is a portable pump that moves liquid out of a drum, barrel or storage tank without tipping it. A motor sits on top of a tube that holds a shaft and pumping element inside the container, so the liquid is lifted up the tube to a discharge hose.
A drum pump is not a submersible, because its motor stays above the container. It is also not a metering pump: it transfers liquid, while a chemical dosing pump feeds it in controlled amounts. For fixed, continuous duty, see our air operated diaphragm pump.

The tube length row is a general guide for standard drums, not a model rating. Exact flow, motor, viscosity limit and materials depend on the model you select, so we confirm them from your liquid and container.
Electric vs Air-Driven Drum Pump
The motor is the part that changes. The same tube can often be fitted with either drive, so pick the drive by your site and your liquid.
| Feature | Electric Drum Pump | Air-Driven Drum Pump |
|---|---|---|
| Power source | Mains electricity | Compressed air |
| Typical use | General and frequent chemical transfer, often with higher flow and head as reported by suppliers | Flammable liquids and hazardous areas |
| Ignition risk | Flammable liquids need an ATEX or flameproof motor | Lower, because the air motor makes no electric spark |
| Flow control | Variable speed on some models | Air regulator changes the flow |
| Viscosity limit | Some series list a higher limit on electric drive | Some series list a lower limit on air drive |
| Weight | Heavier motor | Lighter motor |
| Best fit | Chemical stores and plant rooms with power and non-flammable liquids | Solvent and fuel transfer, or areas with no safe power supply |
Values are typical figures from pump makers' guides and vary by model. Confirm the drive, ATEX rating and limits against the datasheet of the exact pump.
How a Drum Pump Works
- Tube Goes InThe tube goes through the drum opening and a barrel adapter holds it in place. A standard 200 L drum uses a tube of about 100 cm.
- Motor Turns the ShaftThe motor sits on top, outside the container, and turns a vertical shaft inside the tube.
- Pump Section Draws LiquidThe impeller or pumping element at the bottom of the tube pulls liquid in from near the base of the drum.
- Liquid Rises Up the TubeThe liquid climbs between the shaft sleeve and the outer tube to the discharge port at the top.
- Hose Fills Your TankA hose carries the liquid to a day tank or process tank, often feeding a dosing pump.
Key Benefits
Moving chemicals safely starts with not lifting or tipping the drum.
- Empties drums without tipping, which cuts spill risk and manual handling
- Motor stays above the container, so only the tube and pump section touch the liquid
- Light and portable, and the motor can usually be moved to another tube
- Tube in PVDF, PP or stainless steel 316 to match acids, corrosives, oils and solvents
- Suited to low to high viscosity liquids, depending on the model
- Local engineering and after-sales support from Techno Bangla
Which Pump Fits Your Transfer Job?
Choose a Drum Pump When
- Liquid arrives in drums, barrels, carboys or IBCs
- You fill a day tank or dosing tank by hand-held transfer
- You want to avoid tipping or pouring chemicals
- The pump must move between several containers
- The liquid needs a PVDF, PP or stainless steel tube
Choose Another Pump When
- You need exact metered feed. See our chemical dosing pump
- Transfer is continuous or fixed-position, or the liquid is sludge. See the diaphragm pump
- The pump may run dry, because most drum pumps must not
- The liquid is thicker than the model's viscosity limit
- It carries abrasive solids or slurry
Where Drum Pumps Are Used
Any site that buys liquid in drums and needs to move it safely.
- Chemical Transfer
- Hydrochloric Acid
- Sulfuric Acid
- Flammable Liquids
- Oil Transfer
- ETP pH Correction Chemicals
- Coagulant Make-Up Tanks
- WTP Chemical Feed
- Textile and Dyeing Plants
How to Choose the Right Drum Pump
Share these details with our engineers and we will recommend a suitable model and tube.
- Liquid and materials. Give the chemical name and strength. Check the chemical resistance chart for the tube, seal and impeller. Do not assume one tube fits every chemical.
- Viscosity. Centrifugal-type drum pumps suit thin to medium liquids, and many sets list limits of roughly 400 to 1000 mPa·s. Thicker liquids need a screw-type model.
- Flammable or not. Flammable liquids need a spark-safe set: an ATEX-approved air motor or flameproof electric motor, a stainless steel tube and an earthing cable. Polypropylene tubes are not for flammables.
- Container and tube length. A standard 200 L drum takes a tube of about 100 cm. Tell us if you use 20 L pails, carboys or IBCs.
- Temperature and protection. In Bangladesh's warm stores, check the tube's temperature limit. One maker lists about 54°C for polypropylene and about 82°C for 316 stainless steel. Never run the pump dry.
Why Safe Chemical Transfer Matters
Effluent and water treatment plants rely on drummed chemicals. Acid or alkali corrects pH, and coagulants such as alum, ferric chloride or PAC help remove colour and suspended solids, including in textile effluent.
A drum pump moves these chemicals from the drum to a day tank without tipping it, and a dosing pump then feeds the process. See our ETP plant and water treatment plant pages for complete solutions.

Frequently Asked Questions
What is a drum pump (barrel pump)?
A drum pump, also called a barrel pump or transfer pump, is a portable pump that empties drums, barrels, IBCs and tanks without tipping them. A motor on top drives a shaft inside a tube, and the liquid is lifted up the tube to a discharge hose. The tube, seals and motor are matched to the liquid.
How does a drum pump work?
The motor sits outside the container and turns a vertical shaft. An impeller or pumping element at the bottom of the tube draws liquid in, and the liquid rises between the shaft sleeve and the outer tube to the discharge port. A hose then carries it to your tank or container.
Which tube material should I choose: PVDF, PP or stainless steel 316?
PVDF is often used for aggressive chemicals such as strong acids. PP suits many corrosives and acid-washing solutions but is not for flammable liquids. Stainless steel 316 is often used for fuels and solvents. Always check the chemical resistance chart for your exact liquid and strength before ordering.
Can a drum pump transfer flammable liquids?
Yes, but only with a spark-safe set. Makers recommend an ATEX-approved air motor or flameproof electric motor, a stainless steel tube and an earthing cable. A polypropylene tube is not suitable. Tell us the liquid and the area classification, and our engineers will confirm the right model.
What viscosity can a drum pump handle?
Centrifugal-type drum pumps suit thin to medium liquids, and many sets list limits of roughly 400 to 1000 mPa·s. Screw-type versions are reported to handle much thicker liquids, up to about 15,000 cP. Send us your liquid's viscosity and we confirm a model that fits.
Is a drum pump suitable for hot and humid Bangladesh?
Yes, when materials match the conditions. Check the tube's temperature limit: one maker lists about 54°C for polypropylene and about 82°C for 316 stainless steel. Keep the motor dry, store drums sealed, and tell us the liquid temperature when you request a quote.
Can I use a drum pump instead of a dosing pump?
Usually not. A drum pump is built to transfer liquid, not to meter it precisely. Use it to fill your day tank, then feed the process with a chemical dosing pump. Some electric models offer variable speed, but this is not the same as accurate dosing.
How can I get a quotation for a drum pump?
Send your liquid name, strength, viscosity and container size to our engineers by phone or email. We reply with a free quotation for your ETP, STP, WTP or chemical handling equipment, with installation and after-sales support in Bangladesh.
