VEVOR Water Diaphragm Pump, 12V DC, 5.5 GPM Flow, 70 PSI Rated Pressure (40-100 PSI Adjustable), 1/2" MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

Been a year, works perfectly. Used in camper, great water pressure. Had to correct small leak at discharge hose, only needed o-ring!

Hooked it up and it worked great. So far, no issues.

Fonctionne très bien beaucoup de pression régler en usine

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.

All seems very good so far
