1314 Drill Pump750

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.

I bought this pump to empty a 50 gallon rain / water barrel. I worked great! I used a good (heavy duty) plug in electric drill with it. I was surprised how well it worked. Not only did it pump water, it did it fast. For the price, this is a great tool to have around.

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.

Waste of money, not very effective in pumping the water, very loud. Works only with actual drills, will not work properly with impact driver. The stream is very low and regardless of the fact you need to build a rig for this thing it’s just a good idea on paper but looking back I would get myself an actual pump.

I love this little pump. It hardly costs anything (in money) but does the job. However there is a cost of time because of lubrication. The working parts are plastic and have to be lubed with silicone grease because regular gear grease will degrade the plastic. But silicone grease doesn't hold up well against water so the recommendation is to regrease before every use, which I interpret to me once a day while using it. Lubrication requires dismantling the pump - removing the Phillips screws holding the faceplate. I have the pump mounted on a board so that means having to unmount it. There is no shortcut to this that I can find so almost a half hour every day is devoted to this chore. Also silicone grease isn't something I normally have around the house so that's an additional purchase. But even with all that I like the little pump and will buy again when it wears out.

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.

For basic water transfer this worked great. I had back yard flooding from a lot of standing water and because of poor drainage and improper grading I was getting water in the basement. AS a last minute effort before the next storm and snow melt I used this to lower the water level as much as I could to reduce what I was getting into the basement. It took awhile as it was a small flow but it did the job. So for the money you spend you get a decent return.

This was used to evacuate water from a 3 gal underground irrigation tank. A dip tube on the pump's intake side was created using an old cutoff washing machine hose and a short garden hose was connected to the output port. Tip: take the unit apart and lubricate the inside using a "silicone" grease (like Super Lube's brake grease). After use, be sure water is removed from the pump and insert a little more grease on the intake side and allow the drill to slowly lube the inards; allowing it to be ready for the next use with no surprises. Do not use petroleum based grease since this will deteriorate the plastics inside. In my case, the volume of water removed was relatively small and this device worked flawlessly and pumped the fluid up and out with ease and significant pressure. Very pleased.

quality top but need powerfull drill

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.

Esta bomba para uso con taladro ofrece una excelente relación calidad-precio. Su diseño es simple pero funcional, permitiendo el trasvase de líquidos de manera eficiente sin necesidad de equipos costosos. La instalación y uso son muy sencillos, solo se acopla al taladro y comienza a funcionar sin complicaciones. Los materiales son adecuados para su propósito y, aunque no es una bomba de alto rendimiento, cumple bien con tareas domésticas o de bricolaje. En general, una opción práctica y accesible para quienes buscan una solución sencilla para mover líquidos con la ayuda de un taladro.

The product corresponds to the description. The order arrived quickly. I am satisfied.
