About This Product

Milwaukee M12 stick transfer pump delivers superior filtration for uninterrupted pumping in catch basins, water meter boxes, trenches, sump pump pits, and more. Featuring a 36 in. submersible aluminum barrel, this transfer pump provides the extension needed to reach water at the bottom of trenches and difficult to reach areas. Equipped with HYDRO PASS filter technology, its 360° filter maximizes flow in heavy debris, minimizing downtime caused by clogging. Powered by the M12 battery platform, this water transfer pump eliminates repetitive manual pumping and improves control, requiring only one hand to pump, freeing the other to control the outflow. With a 15 ft. maximum head height and an outlet compatible with a standard 3/4 in. garden hose, this pump delivers the power to push water farther out of pits and basins, over walls, and to the ideal deposit location.

Highlights

  • Outlet connection: 3/4 in. brass, attaches to standard garden hose
  • Up to 9 GPM
  • Up to 275 Gal. on 4.0 battery
  • Hydro pass filter: 360° filter maximizes flow in heavy debris
  • 36 in. submersible barrel for easier inlet control and reach
  • Threaded filter designed for easy removal
  • Lightweight and cordless for easy setup and carrying to and from jobs
  • Designed primarily to pump water, with heavy debris in outdoor applications

      Can this be used to transfer automotive coolant from a container to the vehicle?

      Answer This Question

      No — the M12 Submersible Stick Water Transfer Pump is designed for clean water only. It should not be used with automotive coolant, chemicals, fuels, or any flammable/contaminated liquids.

        As the other answer noted is not intended to be use with chemicals, but i been using it frequently for automotive coolant without any issues.. it works!

          Can it be used as sump pump back up, meaning it self activates and stops by itself if no water detected?
          ByAug 9, 2026
          1 Answer | 
          Answer This Question

          No — the M12 Submersible Stick Water Transfer Pump does not have an automatic on/off sensor. It is manually activated with the tool trigger and shuts off only when you release or remove the battery.

            how close to the bottom of a tank will it still draw water from?
            ByApr 17, 2026
            1 Answer | 
            Answer This Question

            The M12 Stick Pump will draw water down to approximately 1/16" of residual water, making it excellent for cleanup and emptying tanks with minimal left behind.

              Can it use for hot water 200 f degree?
              ByJan 4, 2026
              1 Answer | 
              Answer This Question

              No, the Milwaukee M12™ 12-Volt Lithium-Ion Cordless 9 GPM Submersible Stick Water Transfer Pump is not designed for use with hot water at 200°F. The specifications and materials of this pump are intended for standard water transfer applications, and exposure to such high temperatures could damage the pump's components.

                Answer This Question

                Hey, Miguel. The Milwaukee M12™ 9 GPM Submersible Stick Water Transfer Pump features a 36-inch submersible aluminum barrel, allowing it to reach water at the bottom of trenches and other hard-to-reach areas. This makes it suitable for depths up to 36 inches for effective inlet control. Additionally, it has a maximum head height of 15 feet, enabling it to push water over walls or to elevated locations.

                  Answer This Question

                  Yes - look for the M12 battery charger. 48-59-2401 You'd be best off buying a kit and get it with a battery and tool.

                    Milwaukee batteries are easily the most efficient and highest quality batteries for tool applications in the world. They last and last. They use lower voltages and produce the same or more power from their tools than the higher voltage systems. Their products are engineered better.
                    by
                    Milwaukee M12 Cordless Battery Powered Stick Transfer Pump: I have not had an opportunity to use the pump yet, so I understand my comments here may not be helpful to you. My first impression is that the pump has good sturdy build qualities. The metal tube is robust and appears to have a quality coating which will hopefully resist rust and corrosion. The submersible pump unit and its shrouding are a little larger than I was expecting, which is a positive quality for me, but still appear sized to fit through or within narrow ports, bungs, passages, openings, and etc. The quality of the plastic material used to make the pump housing and its shroud/screening appears to be good and likely able to resist damage from use and abuse. The quality of the upper portion of the overall unit appears to be good and equal to what I have come to expect from Milwaukee M12 tools. The threaded hose connection is one part I am hoping will not become damaged with heavy use or damage from an event like dropping the tool. Hopefully the threads will not wear and/or distort. Hopefully the threaded area is resilient enough to not crack or break off if the tool is dropped or if something falls onto it. I am thinking it may be good to use some screen, mesh, or filter like material on the pump intake shrouding especially when using in dirty, gritty, and contaminated liquids. Hopefully this idea is helpful and doesn’t make the pump work too hard and burn out or fail prematurely. Some trial and error is needed for this idea, but if successful it may help the pump last longer. Also: I like the idea of having one of these pumps to use as a beach/camp/emergency shower. So, there are potentially some recreational uses for the pump too as well as many trade, work, and chore related uses.

                    Excellent deal, this starter kit and the larger M12 oscillating tool. The high output 5 Ah battery has a great runtime, even with continuous use. Good addition to my existing M12 battery selection. I really like the compact, lightweight design that offers comparable power to larger voltage platforms. After a few years of using the M12 tools and batteries I would highly recommend them to anyone.
                    by
                    tested it out in a kiddy pool. works really well and the cordless makes it very convenient to use anywhere where there is no power outlet. would definitely buy again. the flow was sufficient for my expectations. the 18v has greater flow capacity so choose wisely.
                    by
                    This m12 transfer pump is powerful and neat. I had a broken pipe that needed to be drained and this thing did the job I wanna say 90% of the water was removed it did a fantastic job well worth the price. .

                    Pump works great for larger projects I recommend the 4ah battery. I used it in a very muddy area and it did not get plugged. I was very impressed and highly recommended.
                    by
                    Awesome pump for small water clean up projects. I use it to empty out bathrooms after I flood test. Runs at about 8 you and is easy to use and extremely quiet. Would definitely recommend a purchase to keep in your tool arsenal.
                    by
                    They are offering me a discount to review this product. I like discounts and I like the m12 platform so what is not to love. These batteries work great. I have a few of the smaller size that aren't enough to keep up with using a bandsaw all day. The 5.0 high output is the sweet spot of having enough juice but not being too bulky to keep on their all day. Whelp, that is about all I have to say about that.
