Milescraft 1314 Drill Pump 750 - Self Priming Water Pump Attachment for Drills - Water Transfer Pump - Uses Common Garden Hose - 750 Gallons per Hour

I bought this little Milescraft drill pump mainly to drain my two large 250 gallon IBC totes, and I was genuinely curious whether something this small was going to handle 500 gallons of water without giving up halfway through. Well... It did! Setting it up is about as simple as it gets. Connect a couple hoses, hook up a drill, and suddenly your drill has a second career in water management. For such a small and inexpensive pump, it moved water surprisingly well through about 100 feet of garden hose, and made draining the totes so much easier than trying to rely on gravity alone. Now, this is not going to compete with a dedicated electric transfer pump, but that is not why dished out a whole $14 for. I needed something cheap, and compact, for the occasional water moving job, and this handled what I threw at it without complaining. After draining the two giant totes I would absolutely call this little red contraption money well spent. It looks like a toy, attaches to a drill, and somehow ends up moving hundreds of gallons of water. I respect that kind of over achievement.

I was on the fence between four and five stars, but sided on five as the pump did what it claimed to do and did it well, but I also checked a thing or two before putting it into use, which is where the potential star loss comes in. But since the listing does make a passing mention of it... This is a simple pump design, one that has been in use for centuries, in many different applications and various forms. It's actually not far off from how some oil pumps work in automobiles, or the motor in air tools. In this case, it's what is called an unbalanced vane pump. Go look it up if you want to know how it works. In this design, the rotor is a stiff rubber and the veins bend over when they reach the small side of the chamber. This also makes it non-directional in it's flow, just move it in a given direction slowly a bit to give the veins time to bend in the correct direction before 'giving it the beans' (and make sure it's greased first, more on this below). Just remember the flow is going to be opposite of the direction the drill spins when looking at it from 'behind' the drill. This is driven by a plastic cog attached to the drive shaft that has 'teeth' cut into in that match a small hole in the middle of the main rotor. If the rotor ever got jammed, you would want this part to give out and let the shaft spin free, not the drill you are holding on to. The design is better than most I have seen, with the body using screws to hold it together. This makes it able to be repaired if the rotor ever fails, and future maintenance is able to be easily performed. The front plate (red part) has a gasket to seal it, and a metal plate sandwiches the rotor to the main body behind the front plate. Don't be afraid to open it up, there isn't anything that is spring loaded inside, and it is easy to disassemble and reassemble, just mind that you don't loose the screws or the one shaft guide piece that sits on top of the plate. And that leads into what the listing should put more importance on and the one caveat I found, grease. When I opened mine up, I found what I would consider a very inadequate amount of grease, and it was the generic beige stuff. I immediately greased it with some silicon based stuff I had (*not* spray!), covering the sides of the rotor, the gasket and the shaft where it rides on the housing. I could see this pump overheating and potentially 'smoking' if it was used long enough at speed with the very small amount of grease it arrived with. But in my experience once I greased with what I would consider an OK amount, it worked very well and self primed (the inlet hose was about 8 feet long and the pump was above the water source by a foot or so). Time will tell how well the rubber rotor holds up, but at this time I'm pretty confident that it will last. I would only suggest that one 'spins' it every so often to keep the rotor veins from getting 'stuck' in the bent over direction.

The Milescraft 750 is a good little pump for moving significant amounts of water. It's advertised as a "drill pump" because it is intended to be attached to the chuck of an electric drill for its power source. As others have mentioned, you can pretty much forget using a cordless drill, unless you've got a very small pumping task. A corded (plug-in) drill is a better choice, and a 1/2" size will do the job better than a 3/8" one, due to the greater power it has. In my application, I coupled it to a 1/2 HP capacitor-start ac motor, because I wanted a relatively compact and self-contained plug-in pump unit for cleaning out my small ornamental pond, as well as other general purpose water transfer tasks. The rubber vanes on the impeller inside this pump have a tight fit inside the housing as they rotate, which makes the pump very effective but also requires a lot of torque to get moving from a standstill. The manufacturer applies a thick grease inside the pump to help reduce the rotating force required, and also recommends applying more of it (or a small amount of light oil like mineral or cooking oil) before each use of the pump. Obviously, oil and grease would not be desirable floating on the surface of my ornamental pond, so I pumped a bucket full of a Simple Green and water mixture through it before using it for the pond. In an application where the pump inlet does not have water directly applied to it before startup, such as a vertical lift and/or horizontal run between the pump and the water source, the length of the inlet hose should not be more than a few feet so the water doesn't have to travel very far to reach the pump, and can get there in no more than several seconds. This type of pump relies on the fluid being moved as a lubricant for the pump itself. Since it consists of rubber vanes rotating inside a plastic housing, you can understand why others (who obviously ran it dry too long) mentioned that it didn't work and smoke came out of it! Water that contains any type of hard or abrasive particles should be avoided, as well as any debris that could get trapped between the rotating vanes. I piped a standard residential water filter housing ahead of the intake port of mine, to collect the algae, plant particles, etc. and prevent them from entering the pump. One error in the specifications for the pump (although not a serious one) is that the shaft diameter is listed as being 3/8". It is actually only 5/16". If you're driving it with a coupling like I did, the size is definitely important to know accurately when obtaining the coupling hub for the pump side. Also, a urethane spider will handle the torque much better than a standard rubber one. All in all, as long as you operate it within the limits of its design, I don't think you can beat the usefulness and performance of this pump for the price. I'm adding an update, and reducing the rating to four stars...when I took the pump out of storage to use it the first time in 2022, I didn't follow my own advice about making sure to prime it. I just hooked a four foot inlet hose to it and dropped it in the water, then turned on the motor. I waited a only a few seconds for the water to come out of the discharge hose, but that never happened. Although the pump shaft was spinning, I discovered that the impeller was not moving. Upon disassembling the pump, I found the teeth of the plastic driving hub on the shaft were totally worn off, and the mating teeth inside the rubber impeller were also destroyed (see the second photo). Since the pump sat for six months without use and was bone dry, the impeller probably got slightly seized in the housing. The manufacturer's recommendation to apply a little mineral or cooking oil inside both ports before each use of the pump would definitely apply to the first use after extended storage, and it's my fault for not taking the time to do that. As a result, my pump is ready for the trash can. I still think this model is useful in the right application. I won't be buying another one, because it's a little too tedious for me to make sure it is cared for correctly, and that's the only way to be sure that it will function when you need it.

Use it one time and then throw it away. It just does not hold up. I read the reviews and one of the criticisms I saw was the lack of grease so I took it apart before and lubricated it with white lithium grease. It worked great draining my first rain barrel. It only took about 10 minutes to drain a 60 gallon barrel. I gave it about 15 minute break, re-greased it and started the second barrel, it started to overheat, and even though I stopped and reapplied grease, the fins themselves had warped and the casing collapsed. So I used it for probably a total of 15 minutes before it broke. Even though the pump itself is really inexpensive. It’s also really cheaply made which makes sense, but I expected it to last longer than 15 minutes.

Works great for sucking sand and stuff from bottom of our hot tub! Tygon tubing zip-tied to a 3 foot wand means I can reach everything.

This drill pump is useful in certain situations, but it’s not as powerful or consistent as the description might suggest. 🔹 Convenient for Small Jobs It’s easy to attach to a drill and works well for light water transfer tasks like draining small containers or moving water short distances. Setup is quick and straightforward. 🔹 Limited Power & Durability While it does move water, the flow rate feels slower than expected unless you’re using a strong drill. It can also struggle with thicker hoses or longer runs, and it doesn’t feel especially heavy-duty. ✅ Pros: Easy to attach and use Works with standard garden hoses Compact and easy to store Affordable for occasional use ❌ Cons: Flow rate is lower than expected Requires a powerful drill for best results Not ideal for large or frequent jobs Build feels a bit lightweight Overall: This pump is fine for occasional, light-duty tasks, but it’s not a replacement for a dedicated water pump. Useful to have on hand, just don’t expect heavy-duty performance.

Great for small tasks. If I have anything I need done fast I pull out my battery operated water stick (available on Amazon) BUT this little devise can get into spaces that my water stick cannot. Points to consider. ONLY WATER, and ONLY non-potable water. Use silicone GREASE often.... directions say after every use.... Once mounted on a device the bottom screws are a little bit hard to get to UNLESS you use a long screwdriver. Since the threads are plastic I recommend greasing them too. On the drill shaft I would have preferred NOT having a smooth shaft.

Best drill pump I've found.I tried 2 other brands and they did not pump as much volume. This is also one of the only pumps I found that can be easily mounted. Make sure you prime the pump inlet and the inlet hose. It drastically improves the amount of water it moves. I had to contact the manufacturer and their support was incredible. They responded quickly, provided technical information and resolved my issue. Highly recommend.

Tut genau was es soll, starke Pumpe mit viel Durchfluss. Habe sie benutzt um die Heizung meines Autos zu spühlen, damit kam sie super klar. Trocken laufen sollte sie allerdings nicht, da geht sie dann vermutlich schnell kaputt.

Funciona bem, conforme recomendado apliquei vaselina depois de cada operação, porém após 12 vezes que utilizei a bomba a engrenagem de borracha desgastou e agora ela gira em falso e não puxa mais água. Eu utilizava para trocar a água do aquário.

My standard green adaptor doesn't fit into this drill pump (see picture). It can only screw in a few threads and unable to reach the inner gasket. Water gush out from the connection because it was not screwed to the inner end gasket. I had tried others adaptor and is the same. It seems like your drill pump thread is not standard. Or maybe can anyone tell me what adaptor size or type I need to purchase? Give me a link for the correct adaptor will be much appreciated. Thanks
