Milwaukee Transfer Pump Kit

The Milwaukee Transfer Pump Kit (Model 2771-21) is a versatile and powerful tool designed for efficiently moving water in various settings. As someone who frequently deals with water transfer tasks, I found this pump to be both a blessing and a bit of a headache, depending on the situation.

Design and Build Quality

The Milwaukee Transfer Pump is part of the M18 system, compatible with all M18 REDLITHIUM battery packs, which is a significant advantage if you already own other Milwaukee tools. The pump itself is compact, weighing in at 7.9 lbs and measuring 13 inches in length. This makes it highly portable and easy to maneuver, especially in tight spaces. The brass inlet and outlet connections (both 3/4 inch) add to its durability, ensuring that the pump can withstand repeated use and connections without wear and tear.

One of the standout features is the self-priming capability, which allows for quick and easy setup. This is particularly useful when you're in a hurry or need to move water from a deep source. The pump also boasts a head height of up to 75 feet and a lift capability of 18 feet, making it suitable for a wide range of applications.

Performance

In terms of performance, the Milwaukee Transfer Pump does not disappoint. I used it to pump 500+ gallons out of a large water tank, and it handled the task effortlessly. The pump's power is evident as it easily moved water through a 50-foot intake hose, even when the intake was nine feet above ground level. The efficiency of the pump is impressive, and it operates relatively quietly compared to other smaller, 110v transfer pumps I've used in the past.

However, the pump's performance isn't flawless. There were instances when the pump refused to start, despite being in good condition and having a fully charged battery. This inconsistency can be frustrating, especially when you're in the middle of a critical task. Additionally, the pump tends to shut off on its own frequently, which can be a significant drawback if you're looking to use it for extended periods.

Battery Life

Battery life is another crucial factor to consider. Using a 5.0 Ah battery, the pump can run for about 30 minutes, which is sufficient for most small to medium tasks. However, for larger jobs, you'll need multiple batteries or higher capacity ones. I found that using a 9.0 Ah battery significantly extended the pump's operational time, allowing me to run it for almost five hours continuously. This is particularly useful if you have a large area to cover or need to move a substantial amount of water.

Durability and Maintenance

Durability is where the Milwaukee Transfer Pump shows some weaknesses. While the pump is well-made and sturdy, it tends to suffer from premature failures. After using it a few times, I noticed a decline in performance, and eventually, the pump stopped working altogether. Upon disassembling the pump, I discovered that one of the DC motor carbon brushes had worn unevenly, causing the motor to jam. Unfortunately, Milwaukee does not provide easy access to replace these brushes, meaning the pump has to be sent to a service center for repairs.

This issue is compounded by the fact that the warranty process is lengthy, often taking 4-5 weeks for repairs. During this time, you're left without a functioning pump, which can be a significant inconvenience. Milwaukee's customer service also leaves much to be desired, as they tend to give customers the runaround rather than addressing the problem directly.

Versatility

Despite its flaws, the Milwaukee Transfer Pump is incredibly versatile. I've used it for a variety of tasks, from watering plants and trees to transferring diesel fuel and even pumping out old used oil. The pump's ability to handle different fluids, although not recommended by Milwaukee, is a testament to its robust design. The clear front impeller cover is a thoughtful addition, allowing you to check for blockages and ensure everything is working correctly.

Practical Applications

For those in the trades, agriculture, or heavy equipment industries, the Milwaukee Transfer Pump can be a valuable asset. Its cordless design eliminates the risk of mixing electricity and water, making it safer to use in wet conditions or during power outages. The pump's high pressure and flow rate make it suitable for various applications, from draining hot water heaters to pumping water from lakes or ponds for irrigation.

Conclusion

In conclusion, the Milwaukee Transfer Pump Kit is a powerful and versatile tool with some notable drawbacks. Its performance and portability make it an excellent choice for many water transfer tasks, but its durability and inconsistent reliability are significant concerns. The lengthy warranty process and limited customer support further detract from its overall value.

Would I recommend the Milwaukee Transfer Pump? It depends on your needs. If you require a portable, high-performance pump for occasional use and already own Milwaukee M18 batteries, this pump could be a worthwhile investment. However, if you need a pump for frequent or heavy-duty use, you might want to consider other options that offer better durability and reliability. Ultimately, the Milwaukee Transfer Pump is a mixed bag, excelling in some areas while falling short in others.
