Milwaukee 2771-20 M18™ Cordless Transfer Pump – 18V, 3/4″ Inlet/Outlet, 480 GPH
The Milwaukee 2771-20 M18™ Transfer Pump is a battery-powered, self-priming unit designed for water transfer applications in service, plumbing, irrigation, and construction environments. Capable of moving up to 480 gallons per hour, this tool is suited for tasks such as dewatering, draining flooded areas, or transferring water between containers or systems.
This unit features REDLINK™ Intelligence, which monitors flow and automatically disables the pump once water transfer ceases—helping protect the pump from dry run conditions. Compatible with all M18™ REDLITHIUM™ battery packs, the 2771-20 provides cordless convenience and is optimized for portability in field operations.
Key Performance Features
- Self-Priming: Automatically primes when connected, eliminating manual setup
- Auto Shut-Off: REDLINK™ system halts operation when water flow stops to reduce wear
- Cordless Operation: Runs on the M18™ platform for flexible deployment on job sites

- Durable Pump Housing: Designed for use in rugged service environments
