I build a variety of “custom” 12v herbicide sprayers for commercial users; specifically, units that aren’t available through big box stores. For the rigs I build, the key value-factors for a 12v pump involve its output-volume (gpm), amp-draw, reliability and durability. I tried this Vevor 12v pump with skepticism, due to its low cost compared to the much more expensive pumps I’ve traditionally used. I’ve been pleasantly surprised with the pump’s performance relative to the previously mentioned factors. For those who mentioned the pump “running hot”, that is a common occurrence when a pump’s power-feed wire isn’t of a sufficient gauge, OR when the device (ie spray gun, etc) doesn’t allow adequate flow-rates (to avoid rapid cycling of the pump’s on-demand switch). This pump is rated for 5.5gpm at “open flow” (zero back-pressure), which is ideal for higher volume needs - but only if the coupled spray-gun has an adequately sized nozzle. This pump isn’t suitable for applications where *less than* 2.5-3gpa is all the volume that’s required or otherwise allowed by a nozzle that’s too small. In such situations use a lower volume-rated pump. The photo shown a very small spray-rig I set up with this pump, which I use for demo-plot applications. Its spray-range is approximately 43’ (with a properly sized gun-nozzle). Very impressed so far by this pump’s performance.

I use these 12 volt pumps for a ATV sprayer on the farm. I have used pumps at twice the price and not has worked as well. Has good volume and pressure. It's heavier than most of the pumps I have used.

The media could not be loaded. This pump is well worth the money. The on demand switch works As advertised. It will pump a steady stream of water 30 ft with a regular hose and nozzle. I have constructed a pump/tank assembly to assist in prescribed burns on farmland. Very please to have this pump connected to the IBC tank and 12 volt battery. Works as I expected. Just completed the project so I have no idea how long it will serve. To be continued……… The next day the pump was put to the test. Prescribed burn all morning, 10 acres +-. Pressure was just what I needed. See video. 200 gallons of water pumped and the deep cycle marine battery still had plenty of charge, in use off and on for 5 hours. Flawless operation and demand switch is immediate and effective. No complaints after using as above.

Failed just out of warranty in two months with limited use. Only used to pump fresh water to water plants. After 10 minutes, and less than 10 gallons it would overheat and shut off. Using it 2 to 3 times a week, it failed in two months. Absolute garbage. No customer support from Vevor.

it uses a classic thermal-current fuse, the one that degrades each time it trips, and they place it near the brushes, where the thermal trip should NEVER go, inside teh motor body with bolts of materials that are GUARANTEED to gall in the body, and heads that strip out when you even think of opening to replace the useless thermal trip with a more reliable/replaceable option if used at 60-70psi as you might for an RV potable water supply this may last a long time, but it says it can be turned up to 100psi, and one would expect that means it NEVER fails to keep doing that for AT LEAST 6 months with a few minutes a day, not so, I hope manufacturers stop EVER using those thermal-current fuses inside motors EVER AGAIN, they ALWAYS fail prematurely and often that causes additional damage to other parts otherwise a great pump, does the job, stays cool, quiet, and full featured, just terrible industry-standard protected motor design(better to simply have no protection at all like that)

I’ve had this for about four months and installed it today. Right away, this unit feels heavier and more solidly built than any pump I’ve bought in the last decade of living off-grid—shockingly sturdy. I didn’t use the Anderson-style connector on the unit, so I modified it to fit my setup. You might be more prepared than I was. For a quick test, I hooked the water tank to one end and left the other end open. Instantly, I noticed noticeably better pressure than my previous 45 psi—of course, that’s expected, but it’s always great to see. I’ve designed my system for 160 psi; many RVs recommend only 45 psi, so do what works for you. Now the unit is fully hooked up, and it’s running hot water with ease and the washing machine without any issues. I love it.

Worked perfect for the first 5 times of using it. Now, it won't pump up, no leaks anywhere, clean filter. It just simply won't build up, it keeps running until it blows a fuse
