VEVOR Water Diaphragm Pump 12V DC 5 5 GPM Flow 70 PSI Rated Pressure 40-100 PSI Adjustable 1

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. Read more

Used the pump for a weed sprayer I have works great , used it one season so far no issues Read more

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. Read more

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. Read more

I ordered 2 of these pumps. They both broke within 2 weeks. Neither will turn on at all now. They both broke the same way. Started off with continuous bypass - the pump wouldn't shut off even after water demand ceased. I could cut power and then after turning back on they would work properly for some random period before failing to stop again. It didn't take long before they just wouldn't start. One of them gives a little vibration when I turn on power like it's trying to start but can't. The other is completely dead as far as I can tell. Very disappointing. Read more

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) Read more

Pump itself has great pressure and flow. So far is holding up good in saltwater application. The included fittings are soft cheap trash plastic which I don't see how they can be durable enough for anything. I had to find decent fittings from local stores, and then the pump threads seemed to be oddball metric sized which required alot of sealant to fit USA NPT fittings. This company would be better off adopting a female NPT on the pump housing or a North Star / tractor supply push button style (o-ring sealed) hose fitting. Read more

Works great, installed on our cabin in the woods to have running water. No issues at all. Read more
