Professional Milwaukee M18™ Cordless Utility & Water Transfer Pumps
Drain water heaters, clear flooded mechanical vaults, empty plumbing trenches, and transfer clean water rapidly with the high-performance selection of Milwaukee M18™ transfer pumps at Ohio Power Tool. Driven by the trade-proven M18™ REDLITHIUM™ battery platform, these cordless utility pumps bring elite portability to remote field environments where dragging extension lines is impossible. Built with rugged, self-priming engineering, the M18™ transfer pump lineup maximizes efficiency and eliminates setup delays across every service call.
High-Volume Delivery: Moving 480 Gallons Per Hour Comfortably
Ditch the manual hand pumps and slow siphon lines. The Milwaukee M18™ transfer pump is engineered around a powerful 1/4-HP mechanical drive system that moves clear water at a blistering rate of up to 480 gallons per hour (8 GPM). Whether you are an agricultural technician routing water storage or a facility engineer managing an emergency reservoir overflow, this cordless tool matches the performance benchmarks of traditional corded utility pumps without the restrictive clutter of power cords.
Advanced Lift and Head Clearances with Full 3/4" Brass Connections
Conquer complex elevation changes and deep utility excavations easily. The M18™ utility transfer pump generates an impressive 18 feet of structural suction lift to draw water out of deep basins, paired with a maximum head height rating reaching up to 75 feet of vertical delivery. To preserve maximum flow velocities and prevent thread stripping under frequent attachments, the pump housing is assembled with rugged 3/4-inch male brass inlet and outlet garden hose threads (GHT).
Intelligent Dry-Pump Safety: Built-In REDLINK™ Cutoff Monitoring
Protect high-value components from unexpected field failures and internal wear. Running a flexible rubber impeller dry will create extreme internal friction heat, melting the blades and destroying the tool block within minutes. Milwaukee eliminates this operational hazard by embedding smart REDLINK™ electronics directly into the tool layout. The instant the water stream drops out and the pump runs dry, the onboard sensors automatically halt the motor cycle, safeguarding your hardware asset completely.

Milwaukee M18 Transfer Pumps Frequently Asked Questions
What is the maximum flow rate and delivery volume of the Milwaukee M18 transfer pump?
The Milwaukee M18™ utility transfer pump (model 2771-20) delivers a maximum fluid flow rate of 8 Gallons Per Minute (GPM), which translates to a high-volume output of 480 Gallons Per Hour (GPH) under optimal baseline tracking heights. Flow velocity will naturally scale downward depending on your total vertical delivery elevations and hose friction limits.
What do the metrics "maximum suction lift" and "maximum head height" mean?
These two structural measurements define the vertical fluid-moving parameters of the tool:
- Maximum Suction Lift (Up to 18 Feet): The vertical distance the pump can mechanically pull water upward from an open source reservoir into the tool inlet channel using a vacuum.
- Maximum Head Height (Up to 75 Feet): The maximum vertical height the tool can physically push liquid out of the discharge nozzle to reach a high drainage basin or upper-floor line.
How does the self-priming architecture speed up emergency field operations?
Traditional utility pumps require the operator to manually pour water down the line to fill the internal chamber before turning the motor on, a slow process that can cause severe motor damage if done improperly. The M18™ transfer pump features an advanced Self-Priming system. Once you attach your hoses, you simply hit the power button; the internal flexible impeller instantly evacuates air from the intake side to pull a clean water prime automatically.
How does the built-in automatic shut-off feature protect the internal impeller?
The pump uses a flexible nitrile rubber impeller to move water. If the source tank runs empty and the pump continues to spin dry, the rubber blades generate intense friction heat flat against the housing wall, quickly melting or cracking. Milwaukee\'s integrated REDLINK™ Intelligence constantly monitors the tool; the absolute fraction of a second the water flow drops out, the system automatically cuts power to the motor, preventing dry-running damage.
What type of hose line must be utilized on the intake side of the M18 transfer pump?
You must exclusively utilize a reinforced, heavy-duty suction hose or short, large-diameter thick-walled hose on the inlet side of the tool. Standard thin-walled consumer garden hoses are highly flexible; the immense vacuum suction pressure generated by the pump will collapse a soft hose completely flat, choking off the water flow and risking dry-pump stalls. The outlet line can utilize any standard garden hose.
Can I safely use this tool to pump gasoline, fuel oils, or liquid chemicals?
No, the M18™ utility transfer pump is strictly certified for clear water applications only. You must never pump flammable or volatile liquids like gasoline, diesel fuel, kerosene, or chemical solvents, as the internal electric motor can generate microscopic sparks that could cause a catastrophic fire or explosion. Additionally, do not utilize this tool to pump heavy wastewater, thick mud, sewage, or corrosive acids, as solids will tear the rubber impeller blades instantly.
Is the Milwaukee M18 transfer pump rated for transferring potable drinking water?
No, this tool is not certified for potable drinking water or food-grade fluid transfers. The internal pump chamber, brass connectors, and flexible rubber impeller tracking materials are manufactured for raw trade utility applications (such as water heater flushings, flooded trenches, and HVAC condensation maintenance) and do not conform to federal NSF safety certifications for human consumption.
What is the maximum water temperature rating this transfer tool can endure?
The M18™ transfer pump handles a maximum liquid media temperature threshold reaching up to 140°F (60°C). This structural threshold is an exceptional asset for plumbing tradesmen, allowing you to hook up lines directly to residential and commercial water heaters to drain hot, scale-filled tanks rapidly without waiting hours for the system to cool down completely.
How many gallons can the pump move on a single standard M18 battery charge?
When deploying a standard, fully charged M18™ REDLITHIUM™ XC5.0 battery pack, the tool can continuously transfer up to 240 gallons of clear water per cycle, allowing you to empty multiple large tanks or deep basements completely before needing to slide the pack onto a sequential rapid charger block.
Where can I buy factory-direct replacement impellers, seals, and inlet fittings?
As an authorized elite distributor and trusted industrial sales provider, Ohio Power Tool stocks a comprehensive inventory of genuine Milwaukee components. We carry factory-direct 45-24-2771 replacement impeller kits, replacement rubber sealing gaskets, brass GHT adapter couplers, and waterproof battery protective replacements to keep your field pipeline operations running at maximum capacity and efficiency.
