  • Strong, made well, better than original pump in camper
Size: 12V, 5.5GPM, 70PSI(Adjustable)
Been a year, works perfectly. Used in camper, great water pressure. Had to correct small leak at discharge hose, only needed o-ring!

  • Works GREAT when properly configured Works GREAT when properly configured
Size: 12V, 5.5GPM, 70PSI(Adjustable)
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. ... show more

  • It works !!! It works !!!
Size: 12V, 5.5GPM, 70PSI(Adjustable)
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. ... show more

  • Functional 12 volt water pump
Size: 12V, 5.5GPM, 70PSI(Adjustable)
Easy to install and pumps water at a rate of 2 gpm against a pressure of 60 psi. Shuts off as advertised at 70 psi. Installed recently so no assessment of longevity.

  • Pump will run hot!! And cuts off !!
Size: 12V, 5.5GPM, 70PSI(Adjustable)
Do not buy these pump. It will only run about 10-15 minute. On a water tank. Before it gets too hot and cuts off. So buyer be careful if you want a reliable pump, don’t buy this one.
