## Description

bayite 12V DC Fresh Water Diaphragm Pump, 4 L/Min 1.0 GPM 80 PSI | Self Priming Sprayer Pump with Pressure Switch, with Hose Clamps, for RV Camper Marine Boat: desertcart.com: Industrial & Scientific

Review: Great high power pump for misting. - Used it for misters and it works great, runs two mister sets and automatically shuts off once the pressure gets too high. This is great. I'd buy this again.
Review: Totally satisfied - hard working small pump - I am seriously impressed with this. My backpack pump, which is of good quality but manual, blew the plastic piston on the pump and a new one was almost 35$!? I decided to look into adding a pump that could provide the output that the pumps wand could handle. This pump did the work! And whats more is that I didnt use the backback sprayer but a 55 gallon plastic drum I bought on marketplace. I attached a long sprayer feeding hose to it and put that down the drum. For power I pull this drum on an old cart I have (can only fill about 40 gallons before it starts tipping). I took a partial electrical cord and attachted one side to a nice ip68 switch and to the pump. then the other put small jumper clamps on so I could put it to my mowers battery. the tank now also has drip irrigation that I can turn on and passively pour out water. But I can also spot spray plants if I want or even strap the hose up top, lock it "on", and drive around my 6 acres spraying Humic and Fulvic acid water everywhere to improve the soil! The little pump has now run 40 gallons almost non stop in one sitting and ive probably sprayed another 50 gallons through it without a single issue. it has a feature where it gets to a specified internal pressure and shuts down until you drop that pressure. If it seems to be running continuously I recommend flowing it and its likely that there is just air in the lines not compressing like water causing this. Id highly recommend this if you want to push water in small tubing. It has a lot of nice functionality and runs easily off a 12v battery using off the shelp bits and bobs.

## Features

- The patented design delivers smooth & consistent flow at all ranges of operation, while drawing low current; 3/8-inch hose barb ports; Vertical Suction Lift: 5ft (1.5m). CUT-OFF Pressure : default 80 PSI. Amp Draw: 3.0AMP.It doesn't mean 4L/min jet at 80 PSI.
- The balanced motor design incorporates precision ball bearings for long life, motor is equipped with an integral thermal breaker.WARNINGS: DC 12V Power supply ONLY!! No AC power. Voltage OVER 14V can burn the motor.
- All marine duty pumps have sealed switches and are finished with a Electro Coating to inhibit corrosion. This is NOT a submersible pump. Caution: Not for use in wet/damp areas – motor is not sealed. Do NOT submerge it in water.
- The soft rubber mounting feet provide good cushion from vibration. When installed correctly, marine duty fresh water pumps provide years of quiet operation.
- The pump in combination with a low backpressure water system can exceed all expectations.

### ⭐⭐⭐⭐ Mine works fine with no leaks. It's loud, buzzy, and vibrates by virtue of what it is
*by L***A on December 2, 2022*

I bought this to cycle cleaning liquids into and out of the heater core for my Jeep. I'm too stubborn to remove the whole dashboard to replace the heater core with something aftermarket and inferior. So I used this transfer pump to cycle a mixture of CLR through the core and then let it sit, cycle it for a minute, let it sit, etc.... This ate up all the rust particles. After that, I used the pump to flush clean water through the heater core and moved onto my next chemical cocktail. Next, I used Prestone's citric acid coolant system flush chemical and cycled that through the heater core with this pump. Let it sit, cycled the pump, let it sit.... What I'm getting at is that neither a basic or acidic liquid being sent through this pump caused it to fail or start leaking. So that's a big win in my book. I rinsed the pump out by putting clean water through it when I was done using it and put the rubber caps back on both ends. I powered the pump with a 5 amp, 12vdc power supply and it worked just fine. The pump itself vibrates so if you have it mounted to anything that will amplify noise, you're going to heat the buzzing. It's kind of loud for what it does. That said, I am sure it's putting out at least a gallon per minute. It seemed to work just fine. I can't comment on how it would work after hours... days... years? of service... But it did what I wanted to do for my project, so it gets a good review from me.
