COVVY DC 12V Electric Water Pump 100PSI High Pressure Diaphragm Pump with 3/8'' Hoses, 4.5L/MIN 60W Self Priming Water Pump for RV Camper Marine Boat Car Washing

The web site does not make that clear, its 4.5lpm or 130psi, but not both. Otherwise its a nice little pump,

The autoscrubber at work needed a replacement after researching the item and installing it worked like new.

Works great

This pump had no water pressure hardly at all not a good product at all and that’s my opinion

The goodPump is very inexpensiveeasy to wire and installVery small foot print.The badVibrates like crazy- but maybe all diagram pumps do?It leaks at 70-80 psi but if you tighten all screws mine stopped leaking but then would start to drip again above 110psi. Very slow drip like a a few drops every 10 seconds, not a big deal since my pump was being operated outdoors.Very low flow at 100 plus psi pressure.... about .25 lpm. My application was for maple sap reverse osmosis. With normal water it is about .6 lpm at that pressure. But if you need it for normal water transfer it works quite well , at 20-25 psi approximately 4 -5 lpm my calculations were all done using 1/4 tubing.Automatic pressure switch will chatter when it gets close to set point. It’s a simple, single point on/off internal button switch. Means that at 60 psi setting it will shut off but then at 58 psi it starts again. In my case , possibly water hammer , the pump was rapidly turning off/on which , will in no time destroy the motor. Mine actually broke-the positive electrical solder connection inside motor, so pump stopped working. I simply resoldered wire, and it was working again. What I did for pressure is I turned the pressure set points to its maximum , around 125 psi so my pump would run continuously, which it ran for about 42 hours non stop without it any issues. It even ran dry for about 4 hours without issues. I believe you would need to add your own differential type pressure switch to make the pump turn off /on in a more controlled manner.In summary the pump was too small for my application, not the pumps fault just my mistake but now I know.The pump is exactly as described, and you simply get what you pay for.If your application is important and you need reliability and something robust, and no leaks, this pump is not the pump.

The media could not be loaded.  Bomne pompe pour le prix Pour le bruit je dirais que ca depend ce que vous en faites. Moi etant tanné de vider le bac de retour deau de mon air climatisé, j'ai acheter cette pompe pour vider le bac plus facilement donc elle ne fonctionne pas en permanance je l'actionne seulement pour vider le bac donc le bruit qu'elle fait importe peu elle fonctionne environ 2 minute chaque fois

Great pump for the money, but the built in pressure control switch doesn't work the best. I recommend that you install a separate pressure switch to control it. The built in switch on my pump would at times build over 160psi. and not want to stop. I put an inline pressure switch and relay for an air compressor that kicks in at 90 and out at 120psi. It has been flawless for a few months in my water meth injection kit.

This item disappointed me greatly. The advertisement on the website showed people washing their vehicles with a hose, apparently being powered by the pump. When I opened the box to inspect the pump, I was flabbergasted to see that the input and output valves were 1/4". I want to see how they connected a garden hose to that.

Works well in my pop up trailer ,i connect it between the water tank and sink faucet and it gives plenty of water.
