12 Volt Diaphragm Pump 3LPM 0.8 GPM 100PSI Self Priming Sprayer Pump 12V DC Fresh Water Pump Water Pressure Switch for RV Camper Marine Boat Lawn (30W)

its works good

Good suction. Good flow. Low amps. No leaks.

Worked great the first time I used it for about 30 or so minutes. About a week later went to spray worked fine for about 5 minutes and then it stopped building pressure. I'd have to let the pump run for 1 to 2 minutes I'd get about 10 seconds of spray then nothing but a few drips.

Lo acabo de montar muy buen remplazo Tiene mucho mas fuerza que el otro que tenia .

Works very well. Would purchase again if needed.

Bought this to make a 5 gal bucket sprayer and so far it's working good. It has good pressure and output and is fairly quiet. I will update on longevity.

Works as advertised

bought since it was the only semi-ideal pump for an RO membrane high-side that wasn't 120vac sadly the pump was not wired properly, one of the motor feeds(the one from the pressure switch or the positive switched supply) was simply jammed into teh moro terminal hole I opened it up because I wanted to see if the pressure could be tweaked and to check on the safety devices it might have I think most of the people complaining it died or was DOA had gotten debris in the inlet(not good for a slurry pump) or had issues with the polyfuse/wiring removing power from the motor, or did not have a good power supply(I needed to add a 12v supercap block to make it run well) after you make sure the wiring is good it handles a range of 85-100psi(not adjustable, sadface) quite well, though it is decently loud and the vibration mounting causes the switch head to tap the surface it is mounted to it works and I made it reliable, but not for the noobs, and they had better fix the loose wiring issue edit: after about 4 months the motor is now overheating and tripping the PTC fuse after only a few minutes of runtime, will be adding a 60C thermal switch into the housing on the new unit to see if it is just really bad at running for long stretches at ~80psi, though 20$ every 4 months aint bad for what you get, even if you have to rewire every unit to have proper crimp terminals and connect to your preferred connector
