Faster water transfers, faster service calls. The M18™ Transfer Pump brings innovation to the cordless tool world with the fastest setup in the industry. With a self-priming pump, you can connect and go faster than ever. The flexible impeller and powerful motor allow this pump to transfer up to 1,817 L (480 gal) of water per hour, generate up to 5.5 m (18 ft) of lift, and 23 m (75 ft) of head. As a part of the M18™ line of tools, this pump is powered by REDLITHIUM™ battery packs (e.g., an XC5.0 battery pack can transfer 908 L [240 gal] of water per charge). The built-in REDLINK™ intelligence technology detects when the pump is no longer moving water and automatically shuts it off to prevent dry pumping. In addition, REDLINK™ technology optimizes the pump's performance and protects it from overloads in extreme conditions.
