Amarine Made 12V Water Pressure Diaphragm Pump 5.0 L/min 1.3 GPM 60W Self Priming RV Booster Sprayer Pump Micropump For Home Garden Caravan/RV/Boat/Marine

I was suprised by size it is small but it did and did a great job.

Purchased this pump for a lakeside camping trip where we have a water slide but no water. This little sucker did awesome. Once primed it was able draw water from the lake via 3/8" tubing (fit perfectly on the pumps barbed ends) and discharged approximately 12' vertical rise. It produced enough flow to wet the slide perfectly. The pump has an anti-siphon valve built in and when shut off held liquid overnight at 12' without bleeding off. Great price and fit our needs well. The pump would only self draw/prime water 6' so fill draw tube with liquid to increase vertical rise (again over 12' of vertical rise was achieved without issue). Used a 12v marine battery and it ran well off and on for three days without drawing down battery.

Worst piece of junk I ever seen. Second one to start leaking by the second use. Only using it with a garden sprayer, small yard for weeds. 7000 sq feet. This is BS. Now second one starts leaking outside of the return window. Contacted the company and they wanted pictures of the leak. Sent pictures and nothing resolved I think they were waiting for the return window to close on purpose. Tried tightening the screws but half were stripped already, no wonder it was leaking.

So far working well

I bought this to replace the pump on my Harbor Freight Greenwood tank sprayer. The specs looked good, but I did not anticipate some basic issues. It appeared that the mounting feet on this pump could be adjusted as they can on the original, but they were not far enough apart and I could not figure out a way to make them so. Also, the inlet and outlet connections are designed for a different kind of hose using compression nuts- the in and out nipples on this pump will not accept a conventional hose and hose clamp. None of this affects my rating even though it affected my experience.I am marking this down to three stars for two reasons: 1) The "instructions" that came with it are written in the most inscrutable "Chinglish" I have ever encountered. I have never seen Google Translate mangle anything this badly, so I cannot guess how they translated this to English. It is maddening and a bit funny in places. 2) You can't really use this outdoors. The motor end of the pump is not sealed. I did not pick up on that from the website description or I would not have ordered it. 3) I have to pay return shipping to return this even though it is Prime.The pump appears to be well made, and the specs are quite attractive on this. So if you can use it indoors and your inlet and outlet hoses will fit on the compression connectors used, you will probably be fine. But it wouldn't work for me.

good

I use a 25 gallon sprayer on my ATV to spray herbicide around my house/ acreage. The more expensive pumps failed if I did not properly clean/ rinse the sprayer out after use. I was tired of spending $60-80 on pumps yearly so I decided to go a cheaper route. I am totally satisfied with this pump knowing I will only get a years use out of it at most. Once the pump is clogged and doesn't work anymore I throw it away and buy a new one. I recommend buying this pump if you are using a sprayer and you realize it will only last so long, not forever.

The design of this pump needs to be revised.I use this pump to pump water from 5 gallon jugs to my refrigerators ice and water dispenser it’s great when it works, mostly it does not because of leakage, (the pump leaks a lot).It puts out good pressure And because it does it leaks.Here’s why:The Motor is screwed to the pump with only two screws it needs 4 or more, the pressure switch is also screwed to the pump with only two screws it also needs 4 or more screws, water seeps out of the sides where there are no screws.I bought two of these pumps but because of the leakage I constantly have to be fiddling with them because the water contaminates the commutator the brushes and the microswitch
