Food grade water pump

I tried the Geyser sponge system some years ago and thought it was a great idea but as is typical for me, I decided to "modify" the original design and one of the modifications included this small pump. I run it off of a few Lithium-ion 18650 batteries (to produce 11-12V) and that works fine. there isn't much more to say about it than that -- it works, it uses little electricity, so far no issues with the pump. BTW this little pump IS LITTLE -- they show the dimensions in the description but it's really not very big and weighs very little too. do not confuse this with the more typical RV diaphragm pumps which are much larger and have much greater output -- this is at max about 1.5-2 LITERS/min whereas ShurFlo RV type pumps are in the gals/min range. for what I need/use this for, it's perfect.

This worked as a great replacement for a bottom load whirlpool water cooler.. the manufacturer did not offer replacement parts and this one actually not only fit but had better specs than the original pump now it fills up way faster and dispenses water quickly. The sound level is also way lower than the pump is replacing.

You can hear it through a closed door. Works great

a little noisy but what concerns me the most is the amount of heat it produces! Ran it for 3 10 sec burst to check fill rate and this pump is extremely hot. seems to be drawing an extreme amount of power just setting at idle.

Old prime pump has been leaking for some time but never noticed till a huge puddle formed under the water dispenser. Was looking for an OEM but ran into this model that runs the same way with the inlet and outlet on the same side. Overall runs perfect a bit louder than the oem but no issues. Clean your reservoir while changing the pump.

Our water cooler was going out. Instead of replacing it altogether, we changed the old motor out for this one. Works like new now!

Easily installed in my water cooler which is no longer manufactured. Rubber hangers make it quite. Described accurately!!!

While this is the little pump that could it is sad that mine did not last a year until one of the diaphragms started leaking. It really is too bad that you cant just buy a pack of diaphragms for this little pump for if you could then it would not be hard to replace them. I do point out that i bought this pump for an experiment that involves using isopropyl alcohol as an inexpensive coolant for a liquid cooled under the covers air conditioner. At least it worked through out the hot summer when i needed it most and the experiment was successful which was a good thing as i have no air conditioner for the room. I give it two stars as it held for the time i needed it most and it works well until it leaks which it might do within a year. I would have added a third star if replacement diaphragms were sold along side this unit but who makes rebuild kits anymore?
