Customer Reviews for VEVOR Water Diaphragm Pump, 20.8 LPM Flow, 4.8 bar Rated Pressure (2.8-6.9 bar Adjustable), 12.7 mm MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

I put this on a spot sprayer and use it to spray fruit trees. It is solidly built and performs as advertised.

I used this pump to draw water from a pond to water a 40 foot pollinator garden. I used it in conjunction with a 12 volt sealed gel cell battery made by the same company. It is drawing water through 14 feet of pvc pipe and water hose that I did fill with water in advance to pre-prime the intake. I also installed a check valve at the far end of the intake pipe to keep the water from draining each time the pump is shut off. I can only say that I am extremely pleased with how well the pump works. I installed a waterproof rocker switch between the battery and pump and installed it all in the ground in a standard valve box. The battery is being charged by a solar panel so the whole system is very simple to use. As soon as the switch is flipped the pump is filling a shrink garden hose to 70 psi in seconds. It works so well that if you shut off the hose nozzle for a couple of seconds the pump shuts off because it is at maximum pressure. As soon as you reopen the nozzle the pump starts right up. You can't go wrong with this pump.

Used for spraying of my fruit trees. Make sure that you flush the pump with water after every use to for increased lifespan.

I'm hooked to my sister's we'll about 30 feet below us, straight up, and helps keep the pressure constant as when we were just on her we'll without this booster pressure would drop alot when in the shower before her pump kicked on and built back up. Works great on keeping the pressure up at all times

I plan to use this as a softwash pump to do roofs and clean other exterior surfaces. I got it all hooked up with about 45 feet of 1/2” hose. It ran great for the maybe 10 minutes of testing and easily shot over the top peak of my one story house. As long as this can last for a few jobs it’ll be worth it for the price. Everything fit and no leaks easy to hook up

I am using this pump for a DIY TIG torch water cooler. It has adjustable pressure so I was able to dial in the exact water flow rate recommended by the torch manufacturer. I wasted time trying a cheaper pump - this was a big mistake - it failed and I cooked a torch. Vevor is rapidly becoming my favorite brand of affordable shop gear. In my experience the quality is noticeably better than Harbor Freight. It's still not Snap-On, but I haven't had any Vevor product fail to perform as needed or break down (knock on wood).

5.5 gpm. Easy to install. Installed under back seat. Quieter than most pumps out there on market. With seat close all here is very low hum. Pumps water from back all way up to my dash to spray hose.

Easy install, takes a bit more power than my old pump lights flicker when running low pressure, i don't think thats a product issue just a power output issue on my 30 amp camper. Great pressure will see how long it lasts.

These are very strong and durable. Going strong after 2 years still. This pump can handle the needs of my food truck!

20 March 2024 I temporarily installed my pump yesterday. The pump, to the best of my knowledge worked continuously for three hours and twenty minutes (3 hrs 20 mins). At the end of that continuous period the pump was hot but still pumping water normally. Since I propose to use the pump one hour on and two hours off during daylight hours the performance yesterday is satisfactory to me. The pump seems to be pumping just over 4 GPM. On Friday/Saturday I propose to use a five gallon container and conduct an exact measurement. Will update thereafter. I will provide periodic updates when the pump is installed permanently. I will update my Star Rating after some permanent use.
