The Milwaukee M18 Brushless Stick Transfer Pump, model 2940-20, is a cordless handheld transfer pump built for moving water out of trenches, vaults, utility pole holes, and other hard-to-reach low spots. This is a stick transfer pump designed for dewatering applications. If you already run Milwaukee M18 batteries and need a faster way to clear water without setting up a bulky corded pump, this tool makes a lot of sense.

On the job, the headline numbers are what get your attention: up to 25 gallons per minute, up to 17 feet of max head height, and up to 1,000 gallons per charge with an M18 REDLITHIUM FORGE 12.0 battery. Those numbers matter because they tell you this is not a light-duty novelty pump. It is built to move a useful amount of water fast enough to keep site work moving, whether you are draining a trench before laying pipe or clearing pooled water before inspection or concrete work.

The long stick design is the real practical advantage here. With a 48 inch submersible reach and an overall length of 63 inches, you can get the inlet down where the water is without climbing into the hole or wrestling with a short-body pump. That extra reach gives you better inlet control in deep or awkward spots and helps you work from a safer, more stable position at ground level.

Milwaukee also built this pump around a brushless motor, which is the right call for a cordless water-moving tool that needs efficiency and service life. Brushless design helps stretch battery runtime while delivering the output needed for steady transfer work. Combined with the 12 amp peak draw, this setup is geared toward high-output pumping while still staying inside the M18 platform tradespeople already use every day.

Where this pump separates itself from a lot of jobsite transfer options is filtration. The HYDROPASS filter is designed to maximize flow in heavy debris and reduce clogging. In the real world, that means less stoppage when the water is muddy or carrying grit and small debris. The threaded filter is also designed for easy removal, which is a small detail that becomes a big deal when you have to clean up and get back to work fast.

Outlet flexibility is another strong point. The pump uses a 1-1/4 inch NPT threaded outlet for maximum flow, and it includes a threaded adapter for use with 3/4 inch standard garden hose connections. That gives you options depending on whether you want max output through a larger discharge hose or an easier setup using hoses you may already have on site.

From a system standpoint, this is a bare tool on the Milwaukee M18 battery platform. It is compatible with all M18 REDLITHIUM batteries, which is a major plus if you are already stocked with packs and chargers. For crews already invested in M18, adding this transfer pump is a pretty easy decision because it fills a specific site-dewatering role without creating another battery system to manage.

This pump is best suited for utility contractors, plumbers, site prep crews, general contractors, maintenance teams, and serious property owners who deal with recurring water removal in confined or awkward spaces. If your work regularly involves standing water in trenches, pits, vaults, or low areas, this cordless transfer pump gives you mobility, reach, and useful output without the hassle of cords or dragging a larger pump everywhere.

Milwaukee M18 Brushless Stick Transfer Pump is the cordless answer for messy dewatering jobs

If you already live on the M18 platform and deal with standing water on jobsites, this pump fills a real need with solid output, smart reach, and better clog resistance than most guys expect from a handheld unit.

• Who it's for: Utility crews, plumbers, site prep contractors, maintenance teams, and anyone regularly pumping water from trenches, vaults, or low spots.
• Why it stands out: The combination of 25 GPM flow, 48 inch reach, HYDROPASS filtration, and M18 battery compatibility makes it more job-focused than a generic transfer pump.
• Worth knowing: This is a bare tool, so bring your own M18 battery and charger. If max flow matters, use the larger discharge hose instead of defaulting to garden hose convenience.

• What battery platform does this pump use? It runs on the Milwaukee M18 battery platform and is compatible with all M18 REDLITHIUM batteries.
• How much water can it move? The pump is rated for up to 25 gallons per minute with a maximum head height of 17 feet.
• What jobs is this transfer pump built for? It is designed for dewatering applications such as trenches, vaults, utility pole holes, and general site water removal.
