Milwaukee 2771-20 M18 Transfer Pump

I bought this to make aquarium water changes easier. It sure does. It takes maybe 8 minutes to pump.out half the water in a 100 gallon tank. Of course it makes quicker work on the 50g and 35g tanks. The pump does have a whine to it but it is not awful and is not loud enough to scare the cat. I have a new 8ah battery and it looks like it could fit a 12 but I cannot vouch for that. I appreciate that the hose fittings are metal. The pump is self-priming which was a must have feature for me. This saves my back and am very happy with the purchase

This is probably one of the best pumps I've ever bought. I use it regularly for diesel, but I've also used it for hydraulic fluid,engine oil, Coolant, pretty much anything you can think of and it works flawlessly.

Awesome pump for pumping motor oil and Hydraulic oil

This transfer pump was purchased for occasional use. It was first used for emptying toilet tanks, when the gaskets were going bad. It sucked out the water so fast, I was shocked. Just a few seconds were that was required to pump out several quarts of water. I prefer battery-powered devices when working around water. It is very effective and surprisingly quiet for the amount of power. I bought a spare impeller, because it is not clear how long it will last if the water being pumped is full of rust particles or other debris. I have not found this to be a problem. Strongly recommended device if you have Milwaukee batteries and chargers.

It’s great pump… when it works. I have had two of them and they both have had to be sent out for warranty repairs. I have two. The first one worked great until it didn’t. It worked properly in the AM and just quit in the PM. I sent it out for repair but l had come to rely on it so much that l bought a second as a replacement. The first one was returned to me working properly but then the SECOND one quit! I sent it out and it was returned in proper working order. Odd. Hence only four stars. My troubles notwithstanding, it’s a great, very useful tool.

One of my favorite tools lately has been my transfer pump. I’m using it to move water from the pond to keep 60 newly planted junipers alive until I get the irrigation system finished. Setup is simple: a two-stage filter with a suction hose on the intake and a 50’ discharge hose on the outflow. The lift is about 6’, and a 5.0Ah 18V battery gives me roughly 37 minutes of run time at 8GPM.

Pump works great, but DO NOT try to use it to transfer gasoline or diesel fuel. I went through 2 impellers before I figured this out. (My fault) I’ve replaced the impeller (easy to do) and now only use it for non petroleum based liquids.

Pump power is great, moves water fast and sped up my process to fill water tanks out in pasture. The battery lasts long enough to fill my 150 gal rubbermaid tub. Would recommend buying a second battery for longer projects. Overall - this meets my needs and would recommend.

Use it to pump different kinds of oil. Works great. Pumped over 300ltrs of hydraulic on 1 battery

Great tool for tradespeople.

Excellent pump drained a cylinder today in minutes

Works great on job site, used to pump from lake, and pump from rain buckets.

It’s a true Milwaukee Use this to water my garden from a tote Make sure to use to use 5/8 hose and 5/8 couplers and a high output sprayer to use this awesome pump to its fullest .
