Customer Reviews for VEVOR Water Diaphragm Pump, 13.25 liters, 55 PSI Rated Pressure (40-80 PSI Adjustable), 12.7mm MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

I have no idea if this pump works well or not because I have yet to get it set up due to the wire that connects to the power source being so short. This might not be an issue for someone who knows a lot about wiring, but I have no idea what gauge of wire I need to purchase in order to connect this to a battery. I sent a message to Vevor asking for guidance but got no response so this pump is absolutely useless to me. I will have to order another pump from somewhere else that had more than a few inches of wire..

Generally ok but shuts down on overheat after about 1 hour continuous watering. Cools down after 30 mins and restarts. Will add heatsink and fan

BON DEBIT DE POMPE ET SILENCIEUSE

Just installed this on my boat yesterday. Everything works except the nozzle. Had to go to local hardware store to buy a nozzle. Hopefully vevor will send me a replacement and hopefully it's better quality as I have the same nozzle on my retractable hose reel that I purchased from vevor and it has failed also.

Works okay with expected pressure on a mild weathered day. On a hot summer day (30 degrees plus) it only has a duty cycle for a couple of minutes and will shut down for a period (10ish minutes in the shade)

Leider ist der Druck bzw Magnetschalter nach 1,5 Jahren defekt und man bekommt keine Ersatzteile

This model is sold as continuous duty and mine quits after about 10 minutes because it over heats. That’s not continuous duty!

Der Schalter hat keine ausreichende Hysterese, sie schaltet ständig aus und an. Das heißt im sekundentakt, es rattert.

OK if you don't have power failures and data on it is important in rural setting and the history it keeps. Should have checked if it had a battery backup

Didn’t work out if the box. Verified polarity before hookup but it just hums when powered and pops fuse
