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 110 PSI Adjustable for RV Camper Marine Boat Lawn

So far so good. Works great on my 15 gallon sprayer,.

Installed into my jet ski just to pump out the small amount of water that collects at the bottom of my jet ski. It works well since it is self priming and I didn't have to install the pump in the bottom of the bilge.

I purchased this pump as a replacement for my 15 gal spot sprayer pump that I use on my lawn. It is the same physical size but pumps at a much higher volume and pressure. The valve on the spray wand will barely shut off. It was not advertised for this use so not faulting the pump but if you're considering it for the same usage, keep that in mind. I was shocked at how well it pumps!

the lift of this pump is amazing. I bought it to refill my rain barrels from a low volume well . I measured 8ft from the ground level to the water level and another 4ft to the top of the barrel, easily giving 12 ft of head with good pressure, the volume is a bit low, about a gallon per minute, but perfect for what I use it for. It pumps the well cavity dry in about 2 minutes. it is self priming and I dont need to use a check valve on the line. I gave 5 stars for longevity but this is only a guess, I will update this post after I give it a longer try.

I’ve got two of these pumps managed by two Cytron MD-A20 controllers, Arduino, and Pi for moving water for my drip irrigation system. They’re really solid, and so far no complaints after two months of the first being installed. They run about 15 minutes a day based on temperature and schedule. They’re audible, but not loud, and I’m really pleased with their performance.They do eat the power, so just go in expecting to charge the battery with either solar or nightly charges, and these won’t disappoint.

Easy to have it, install and works well. This little cheap pump fit my application perfectly. sometimes it quit working I thought it was broken,later on I found out mostly due to low battary of my application. The pump give very strong pressure after tested, it even blew my hose off when first to use,hahahah! Two hose clamps can with pump are extremly helpful, thank you!

I use this pump to transfer water from 55 gallon drums to a 300 gallon tote at our cabin. It works well but it takes about an hour to do one 55 gallon barrel. Do not think you will replace your RV surflow pump with this. It is much smaller and not capable of the volume an RV water pump is. I have also used it to water some trees and it worked great for that. For the price it is good so far. We will see how long it lasts.

Update -- the pump stopped working altogether. The connection between the motor and the pump is soft plastic and just expanded to where the motor wouldn't move the membrane anymore._____________I only had the pump actually in service for about a month and the pressure switch failed.I was able to bypass the switch and since I have the pump on a timer it still functions okay. I don't like running like this though. I think another reviewer mentioned replacement pressure switches were available. I'll need to look them up.Other than the switch, it seems like a decent pump. The flow rate is just what I needed for my HPS Aeroponic system. It's a little noisy, but compared to other membrane pumps I have, it's not bad. I was able to put in in a box with some sound proofing and can barely hear it.
