12V DC Fresh Water Pump with 2 Hose Clamp 12 Volt Diaphragm Pump Self Priming Sprayer Pump with Pressure Switch 4.5 L/Min 1.2 GPM 80 PSI Adjustable for RV Camper Marine Boat La Transparent color (2)

Used it to replace the water pump on my Petra sprayer. Super easy to hook up and now I’m getting even more pressure when spraying.

This pump does the job 12 volt DC can take water High and it decent volume but I've had smaller that have pushed as much as it with a lot less noise. This units noise and vibration is it downfall. It is noisy, seriously. If you can get around that then you're all good as it has sturdy connections and a decent gauge of wires. Mine has been on nonstop for about a month and a half directly in the Sun pumping unfiltered Rainwater with fish waste without a hiccup. I'm not saying that it's, it's best use case, but is work for me in that application. So in summation: tough little unit stands up well in totally exposed elements and if you don't mind it's incredibly loud noise it's two thumbs up and four stars because of the noise

Perfecta para dosificación y tratamiento de agua.

You get what you pay for, and this is on the cheaper side. No adjustment for the pressure cutoff leaves it priming it self every so often to rebuild pressure, and the unit is quite noisy.. but works reliability in my diy camper after about 6 months of on and off use

Works great 👍
