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

Nicely built, quick shipping.

Work perfectly for a home built liquid fertilizer spreader. Price was very reasonable and performance exceeded expectations. Used standard mounting layout so it was an easy installation for my project

Fonctionne très bien beaucoup de pression régler en usine

The mounts are pretty stout and isolate the pump from my cabinetry so I don’t get any vibrations. After making pressure adjustments and shut off valve settings, the water flows really smooth. Huge upgrade from my old pump and the build quality seems good as well.

The pump works well for my 3d resin printer resin filter setup. It does have a slightly loud hum to it, but it isn't too much or over bearing. It only runs for a short time anyways. Overall, this is a good pump for the money. Good value buy.

Higher volumes than the previous one and adequate pressure though it says you can turn it up

I made a dechlorinating portable watering system with this durable little pump! It has worked well for over a year. It worked out of the box without adjusting anything.

Got it as a backup pump for the road ... but after testing it I installed it as primary .. It's 3 times less noise than other pumps I've used and offers very light 'buzzing' vibration instead of the usual shaky vibrations. BONUS: provides higher pressure and faster flow than more expensive pumps ... will see how long it lasts.

I haven't installed this yet. I'm in the process of refitting a sailboat. This will be the water pump for the fresh water system.

Good little pump - Does not come with any battery leads. Have to buy SAE battery connector separately.
