Overview
This bundle pairs the Milwaukee 2771-20 M18 Water Transfer Pump with the Milwaukee 48-11-1850R M18 REDLITHIUM XC5.0 Oil & Solvent Resistant Battery, so the bare-tool pump arrives with the XC5.0 pack its runtime rating is based on. Model Numbers: 2771-20 (M18 Transfer Pump, tool only), 48-11-1850R (XC5.0 oil & solvent resistant battery).
The M18 Transfer Pump moves water at up to 480 gallons per hour (8 GPM), generates up to 18 feet of lift, and delivers up to 75 feet of head height. Milwaukee positions it as the industry's first cordless transfer pump. Self-priming design means you connect the hoses, power it up, and go. It uses 3/4" brass inlet and outlet connections, a flexible impeller, and a cast aluminum build.
Onboard REDLINK Intelligence detects when the pump stops moving water and shuts it off automatically to avoid dry pumping, and provides overload protection in abusive conditions. Milwaukee rates the pump for up to 240 gallons moved per charge on an XC5.0 battery pack.
The 48-11-1850R is an M18 REDLITHIUM XC5.0 battery with an oil and solvent resistant housing. It gives more runtime than a compact pack without stepping up to a bulkier battery, and it fits every M18 tool, so it moves to your drill or impact when the pump is done.
Who should buy it? Plumbers, HVAC techs, facility maintenance crews, and contractors who drain systems and clear standing water often enough to want a purpose-built cordless pump. Because a charger is not included, it fits best if you already own an M18 charger.

Pro Tip
Budget around 240 gallons per charge on the included XC5.0. For a bigger drain-down, stage a second charged M18 pack before you start so the REDLINK shutoff isn't the first sign you ran dry on battery.

Tool Nut's Take
The Cordless Pump, Ready to Run
The 2771-20 is the tool that replaces the wet-vac-and-bucket routine, and this bundle puts the right battery on it out of the box.
- Who it's for: Plumbers, HVAC techs, and maintenance crews on M18 who need a portable, self-priming transfer pump.
- Why it stands out: The included XC5.0 is the pack Milwaukee's 240-gallon runtime rating is based on, and its oil and solvent resistant housing suits mechanical-room work.
- Worth knowing: No charger or hoses are included. One XC5.0 is rated for about 240 gallons, so larger jobs need a second pack.
Common Questions
- How much water can it move per charge? Milwaukee rates it for up to 240 gallons per charge on an XC5.0 pack, which is the battery included here.
- Is a charger included? No. You will need an M18 charger.
- Does it protect against dry pumping? Yes. REDLINK Intelligence shuts the pump off automatically when it stops moving water.
- Will the battery work in my other M18 tools? Yes. The 48-11-1850R is a standard M18 XC5.0 pack with an oil and solvent resistant housing.
