Description

Milwaukee 2771-20 M18™ Transfer Pump

Instant Self-Priming Setup. 480 GPH High Flow. Intelligent Dry-Pump Protection.

The Milwaukee 2771-20 M18™ Transfer Pump brings groundbreaking cordless innovation directly to the utility and plumbing industries. Moving far beyond traditional, heavy transfer pumps that require you to manually pour water into the housing before starting, this portable powerhouse features a specialized self-priming pump mechanism. This allows plumbing crews, HVAC techs, and facility managers to simply screw on their inlet hoses, slide in a battery, click the power toggle, and watch water move immediately—making it the fastest setup in the commercial marketplace.

Engineered with a heavy-duty flexible impeller, this utility pump moves water at a blistering rate of up to 480 gallons per hour (GPH) while generating a powerful 18 feet of suction lift and a crushing 75 feet of maximum head height. Powered by a single M18™ battery, it can safely transfer up to 240 gallons of water per charge when paired with a standard XC5.0 power pack. Backed by REDLINK™ Intelligence, the pump features a smart auto-shutoff safety monitor that automatically cuts electrical power the exact instant the inlet line runs dry. This completely prevents dry-pumping friction from destroying your internal rubber impeller blades, maximizing the life of your equipment.

Why the Milwaukee M18™ Water Transfer Pump is a Service Truck Necessity:

  • Fast Self-Priming Activation: Instantly draws liquid upward through the inlet pipe without requiring a manual water prime pour during initial setup.
  • 480 Gallons Per Hour Flow: Blasts through high-volume maintenance applications, draining standard water heaters and reservoir tanks in minutes.
  • Smart Dry-Pump Protection: Integrated REDLINK electronics monitor liquid flow, instantly shutting off the motor when water stops to save the impeller.
  • Rigid 3/4" Brass Connections: Features heavy-duty, clean-threaded intake and outlet ports that screw securely onto standard North American garden hoses.
  • High-Volume Head & Lift Lift: Generates up to 18 ft. of vertical suction pulling power and 75 ft. of delivery push to empty deep basements and multi-story zones.

Frequently Asked Questions

+ Does this cordless transfer pump include an M18™ battery or a charger?
No. This SKU (2771-20) is the "Tool Only" (Bare Tool) version. It includes the bare transfer pump unit with a clear viewing viewport and internal impeller block. M18™ lithium-ion batteries and wall chargers are sold separately.
+ Can I use this pump to transfer gasoline, diesel fuel, or chemicals?
Absolutely not. This pump is engineered and rated strictly for clear water applications (such as draining water heaters, gray-water basin tanks, or rain pools). Pumping volatile fuels like gasoline, kerosene, or corrosive chemicals can cause explosive spark hazards, destroy the rubber impeller seals, and instantly void your warranty.
+ Is the internal rubber impeller a consumable item that needs replacement?
Yes. The flexible rubber impeller sits at the core of the pump housing and will wear down over hundreds of hours of friction use. If your flow rate begins to slow down, you can quickly restore factory performance by purchasing a low-cost Milwaukee Replacement Impeller Kit (45-16-0310).
+ What type of hoses are recommended for the water inlet?
For the intake (suction) side, you should always use a thick, heavy-duty, or reinforced suction-rated garden hose. Traditional thin-walled, cheap vinyl hoses can crimp or completely collapse flat under the immense vacuum pressure generated by this 18-foot suction lift motor, cutting off your water supply.
