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)

Easy to install, great pressure. Works great, and it’s pretty small and will fit inside compact areas.thus pump function awesome. Very durable.

Worked great. Used it on a 10 gallon yard sprayer. Adjustable pressure.

It doesn't say how many Amps it needs exactly but based on the power supplies that didn't work I'd say 12v 4A is the minimum that it wants. Using a 3A makes it cut out sometimes.But although you can't adjust pressure (a definite minus), for the price and features, it works.To adjust pressure higher, you need to loosen the press switch housing. It does slighty raise the cut in to cut out ratio. I got mine to 120psi cut out this way with 95psi cut in... My first pump on its own hit 150psi...but I don't think that's safe... It raised up as it broke in...or got clogged?Some pumps have very poor self priming, others are great. If you get one that is poor, return n replace it, it's supposed to prime well.An alternative to save time (cuz I got 2 In a row that had zero suction even if you dipped it water.Is to take the 5 screws on the front and back off and wiggle the "+" looking plastic piece and add a light coat of silicone paste to it and reassemble as you found it (don't forget the spring).This can get jammed if it's been sitting a while or unused.

I purchased this at the end of the year for a green house project. When I got it, I hooked it up to verify the motor worked and set it on the shelf. Life has gotten in the way but finally got around to finishing the project. I hooked up the pump and power, motor runs but no water. Took the head off the pump to realize the motor will not run this pump. The bearing fits into the actuator so the motor just spins freely. Waste of time and money. Obviously too late for the refund

For the price it does what it needs to do. There is one issue and that is the filter they put in there. It really clogs very easily

Update: dated 5th May 2024I purchased three pumps as follows: March 2020, September 2023 and November 2023.The one that I purchased in 2020 is still functioning like a boss while, unfortunately those purchased in 2023 have stopped functioning.CUSTOMER SERVICE WAS GREAT, THEY IMMEDIATELY REFUNDED. I will purchase the pump again.My house is a two storied structure. Because of low water pressure on a regular basis I utilize water tanks and pump water upstairs using AC pumps to the faucets in my house. Not long ago both AC pumps started giving trouble so I decided to experiment with this DC pump since I already had the batteries in preparation to setting up a solar system.Quite naturally the water pressure is not the same as the AC pumps, however, the water flow to the shower head is sufficient to have a comfortable shower. NB: Two showers cannot be operated together.If thee is a power failure from the Grid my life continue to move along because I now have an uninterrupted water supply.I highly recommend these pumps for use similar to mine.Today I will connect an additional pump to the system and monitor the water flow to the shower upstairs.

I purchased this pump from Amazon and found it efficient but very noisy. It works well, but the loudness is a significant drawback. Good performance, but noise reduction is needed for future models.

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