The Milwaukee Tool M18 Transfer Pump is a self-priming, cordless transfer pump designed with a flexible impeller that, once turned on, starts pumping water instantly from inlet to outlet without the need for additional priming assistance from the user. The M18 can pump up to 450 gallons per hour, can produce an 18' lift and has a 75' head height. Equipped with REDLINK Intelligence, the transfer pump is protected against dry pumping by switching off when the application is complete and the tool begins running dry. The M18 includes the M18 transfer pump, 3/4" brass fittings, an extended capacity battery pack and multi-voltage charger.
