Fielect 5-12V Self Priming Diaphragm Pump Motor Shock Absorption Water Pumps DC Diaphragm Pump 5mm Copper Mouth R385 with Water Pipe

The media could not be loaded.  This pump worked well for my application.I have a soap dispenser in my kitchen that we use to dispense dish soap. In the recent past I started to have trouble with the dispenser. . It constantly lost prime over night. I decided to replace the dosing pump with this one. Having this pump installed solved all my problems. The dispenser works well every time. No more priming issues, delivers a dood dose of soap and operates very quietly. Since this pump is able to build pressure, unclogging the soap dispenser can be easier done.

I tried it out and am happy with the performance. Picked up water right away from the bilge and pumped out. Got item for the economy boats!

Works well. Flow can be adjusted easily with a dimmer switch. Only problem is that the water pipe (tubing) supplied is too small to fit over the inlet and outlet connections. Their outside diameter is 1/4"+ and the tubing has a 1/8" inside diameter. I had to buy tubing of the right size.The power supply wires have to be soldiered onto the connections.

Used this in a large RC boat to cool the electronics. Unit is pretty quiet if you mount it using the rubber feet. I suspect with age that will change but I am only by it when it is turned on and off it goes. I did not use the voltage resistor included as I supplied 5V from the rig. Works great and is self priming. Will be purchasing more for other projects.

I appreciate the variable voltage support on this pump. When I first installed it, it ran as expected. After a few months it stopped working. I was past the original return period so I ordered a replacement pump. The second pump was DOA. I replaced that pump with a third and just received another DOA today. This pump is a wonderful value if it works. It seems that getting a working pump is a completely random occurrence.

Works great. Totally silent. No prime needed. At one to two liters per minute it's not the most rapid transfer but at this price I'm all around happy.

I bought this pump, didn't use it cause it's fittings was way less than the advertised 6mm ID in the pictures.First, the description says it uses 6mm ID fittings.These fittings are not 6mm ID. They are 3mm. See the included picture.Then I filled up a bucket with gallons/quart measurement lines. Fed it power from my 12v power supply with plenty enough amp output. It moved 0.5 gallons in 105 seconds. According to my math that is 0.2857 gpm, or 1.081 lph. Which would exactly half the rated gpm at 12v.

Functions as expected, brushed motor makes speed control simple, only unknown is if it will last in the application I'm using it in, running it off of a relay to lubricate CNC mill.

Worked straight out of the box. Didn't measure the flow rates so can't comment on that. Self primes as promised. Used a generic motor controller to vary the speed with a wide range of output flow rates achievable. Can't comment on the longevity at this point.
