TERA PUMP Manual Drum Pump TRDRUM40 — Heavy-Duty Lever Action, 5.5 GPM, 47.2" Hose

The TERA PUMP TRDRUM40 is a heavy-duty, battery-free manual drum pump that transfers up to 5.5 gallons per minute for clean and reliable fluid dispensing from 15–55 gallon barrels.

This lever-action drum pump is engineered for jobs that demand portability, ruggedness, and simple one-handed operation. Built with a segmented telescopic suction tube and a corrugated flexible discharge hose, the TRDRUM40 adapts to common drum sizes and a wide range of liquids — from light oils and diesel to potable water — without needing electricity. A built-in 2-inch NPS bung adapter and an adjustable air vent cap let you control flow and seal compatibility quickly on site.

How fast and how much liquid will this pump move?

The TRDRUM40 uses a manual piston action to deliver a maximum flow of about 5.5 gallons per minute under typical pumping motions. You can sustain steady transfer for rapid drum emptying, especially useful for 55-gallon barrels where speed matters.

• Max flow: approximately 5.5 gallons per minute (manual operation)
• Optimized for quick removal from full 55-gallon drums
• Flexible 47.2-inch corrugated discharge hose for reach and routing
• Lever-style action for single-handed pumping

What liquids and containers are compatible with the TRDRUM40?

This pump is compatible with a broad range of fluids including petroleum derivatives, light oils, diesel, kerosene, solvents used in thinning, and even potable water (BPA-free). The three-piece segmented suction tube fits most standard 15–55 gallon drums and includes a 2-inch NPS bung adapter for common drum openings.

• Works with petroleum products, diesel, kerosene, and lighter solvents
• Suitable for soaps, detergents, mild acids, antifreeze, and potable water
• Segmented telescopic tube: ~34.4 inches, fits 15–55 gallon barrels
• 0.75-inch outer diameter suction end and built-in 2-inch bung adapter

How do you start, stop, and control the flow safely?

Flow control is mechanical and intuitive: twist the air vent cap clockwise to open a siphon vacuum for continuous flow and turn it counterclockwise to slow or stop discharge. The pump’s corrugated hose includes an integrated nozzle holder to keep the outlet secure when not in use, minimizing drips and mess.

• Air vent cap provides straightforward flow start/stop adjustment
• Nozzle holder on hose keeps dispensing tip stowed and tidy
• Manual lever action enables metered transfers without electricity
• Portable design reduces need for tools or external power

What maintenance and warranty support should I expect?

Few moving parts make routine upkeep simple — rinse or flush after pumping reactive chemicals and inspect seals regularly for wear. TERA PUMP supports the TRDRUM40 with a 1-year warranty against manufacturing defects and has a decade of product experience informing parts and service decisions.

• Low-maintenance piston design with easy-to-clean hoses and tube segments
• Recommended: flush after use with corrosive or contaminating fluids
• 1-year manufacturer warranty on defects from TERA PUMP
• Proven company experience: over 10 years manufacturing pumps

Who this is for: the TRDRUM40 is designed for mechanics, farmers, fleet and equipment managers, contractors, and emergency-preparedness planners who need a dependable, electricity-free solution for transferring liquids. It suits workshops and job sites that require quick drainage of drums, safe dispensing of potable water in outages, or controlled handling of oils and mild chemicals without the complexity of powered pumps.
