CrocSeeDC 12V Mini Food Grade Self Priming Diaphragm Fresh Water Transfer Pump 1.3LPM, Replacement Pump for Ice Maker, Coffee Machine, Water Dispenser

Being a lazy engineer, I decided to convert my Gaggia espresso machine to automatically refill, using this pump. What a pleasure now listening to the light buzz of the pump when I prepare an espresso or a caffè latte.

The pump in my Gevi ice maker failed (my fault, I didn't do the descaling/cleaning as I should have), and I didn't find an exact replacement. I did find this one, and it looked pretty similar. It is the same size and fit into the OE holder perfectly.There are three basic differences from the stock pump here, and they're not deal breakers but they need to be known before you start.1 the ports are smaller than the stock, and won't directly seal to the original tubing (read on for the fix)2 ports are both end facing and this impacts, a touch, the fix for #13 the electrical plug with the pump doesn't go onto the existing boardWork arounds:1/2 is order the 3/16th tubing recommended in the bundle on the order page. The 3/16th tubing can be cut to a 1/2 to 3/4 inch length, put onto the pump outlets then the original tubing goes beautifully over it and the clamps fit (eventually, requires some fiddling as they're really close when installed).Cut off the original connector, and the new one, splice the old onto the new. Works perfectly.And I descaled the heck out of it. Works like new.

Loud when ran on 12/9 volts.Silent if you run it on 5v, runs just fine on USB power, only draws about 0.5A under light load.Tube barb says 1/4" but 1/4 ID tubing is too loose to allow the pump to get suction, using standard aquarium airline hose works but is a bit too tight.Going to be running this pump continuously under very low load, we'll see how it holds up over time.

Not texting this as it's max specs, but did a great job of pumping water from a jug to my Brita. X barely vibrates, I just left in on kitchen counter top. You can hear it, but I don't let it run for more than 3 minutes at a time, so not a concern for me

My issue is that it’s not strong enough to pump a high enough volume of water for a water dispenser. It’s a good dependable pump, but it struggles with my dispenser daily!

I use this to transfer wine during bottling and it works really well. One thing to note is, the pump doesn't have a pressure regulator so if you want to control the flow don't crimp the outlet side. Instead slow the flow of the inlet. This will prevent the hose from blowing off

I was looking for something that was maybe three times the size of this pump. Did not try it out.

A little louder that I thought it would be, but worked except the hose tip is smaller than the hose I was using
