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

seems to work well after getting the bypass and pressure switch adjusted. The pressure switch seems to chatter the motor(cut in and out rapidly) as it reaches the shutoff pressure. I am using this to pump water from a tank into a pressure tank and drip irrigation system. I have the bypass closed completely since it is filling a pressure tank and then can shut off for 15 minutes before needing to pump again. it seems to put out the advertised flow rate. my only complaint so far is the threaded fittings don't seem to be true pipe thread as they wont tighten up without bottoming out so you will need to use alot of thread tape. Also the strainer it comes with works well but filters from the inside out so you cant see when its plugging up.

Good pump for the money i have 2 of the 70psi ones and both of them I had to turn down the pressure because they wouldn’t shut off. Id probably get the 45-50psi one next time.

Have 2 of these and got the 70psi and had to dial back the pressure screw to get to shut off. Not a bad pump for the price.

We bought this to replace our water pump at the cabin. It works great!! This was a great price and arrived quickly!

Ottima pompa, buoni gli attacchi con connettore rapido però sconosciuti in commercio, almeno nella mia zona. Forse con ingresso ed uscita filettato da 1/2" , benché soluzione vecchia, sarebbe stato più pratico.

Nicely built, quick shipping.

It did take sometime for it to show up, but it is definitely a beasty pump. May be small but it definitely has some heft for it. Can hardly wait to use it after I get all my water lines finished up. I'm going to use it for my off grid house.

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

Sehr gute Wasserpumpe für das Wohnmobil. Gute Qualität und günstiger Preis. Schnelle kostenlose Lieferung.
