Driew 3W DC 3.5-8V USB Water Pump with Power Cord, Solar Mini Submersible,Brushless,Waterproof (1, Black)

I bought this to replace a pump in my cat water fountain. The old pump was working but getting very noisy. So far the new one is quiet and working, hope it stays quiet!

Not the most powerful water pump but it is a low powered water pump. I put it in a cooler to make a water to air cooler with a coil. It works and pumps water up and through the coil with no issues. At first it would not pump water out of the coil with the lid up. When I lowered the lid, the water started coming out. I ran it for 2.5 hours with no issues with the pump. Takes all of 1.2 watts to operate, as soon as you plug it in it starts up. I cannot hear any noise from it at all. To tell that it was running I touched it and felt it vibrating. I put a usb tester on it to find out how much power it draws. 5.1 to 5.2 volts at 0.21 to 0.22 amps. About 1.2 watts. Not enough to register on the display of the power bank I used.

I’ve purchased this 2-pack twice. .It’s compact, easy to use, and runs well on a USB power bank. Just keep in mind: it’s a bit delicate and may not last long-term.

If submerged in water just below the outlet spout, it shoots about 4" of water straight up into the air. If the outlet is itself submerged then I get about 2-3" of water above the surface. I am really pleased with these pumps and the longevity of them so far. They run off any universal USB power supply just fine. I wish I'd known about these earlier. I had a table display that the pump died and was eventually the whole unit discarded. This would have been a perfect replacement for that pump. No issues or faults with them thus far. Good price too. I found if I need to clean them, I simply run them under a hot water tap (with the pump turned OFF) and allow the water pressure to do the rest. First let the water from the tap shoot directly into the inlet for a few seconds and then let it shoot directly into the outlet for a few seconds. You can actually remove the plastic screen over the inlet. Not sure if it is designed to be removed but I got it off and it clipped quite firmly back on. So cleaning is really easy without removing the filter anyway.

A proper water pump replacement for the CatIt Water filter fountain. It's quiet and pumps well. My only con is, that they eventually start making a loud humming/buzzing noise after several months. Which becomes annoying to the cats and myself. Reason for replacing.

Approximately 6 months and even with monthly cleaning this pump broke. Noise increased over a few days at which point the stopped working. Absolute garbage. Good to see it is no longer sold.

I use these pumps in a Catit-branded water fountain. From experience, the pumps should be considered consumables that will require replacement at least annually, if not more frequently. Whisper-quiet when new, the pumps will eventually develop a humming sound. The volume of the sound will depend on (a) the age of the pump (older = louder) and (b) whether or not the outlet spout is in contact with the fountain itself; the corresponding vibration serving to elevate the perceived volume of said humming. Even if or when the pump continues to operate sans annoying sounds, its output (i.e., water flow) may be observed to slowly diminish as it ages. The inexpensive replacement cost and ease with which new pumps are installed makes it easy to live with their mild deficiencies. This is doubly true when the Catit fountain one owns doesn't easily accept other pump designs, if they can be made to fit at all. Finally, be careful when purchasing a replacement pump to ensure the left- or right-side orientation of the vertical output shaft matches that of the pump being replaced.

These little pumps power the cats' water fountains. Two cats, with a fountain each, and I change the water on a monthly schedule; but I found Malibu particularly was upset while her fountain was being washed (she does drink lots) so I bought two more fountains: that way I can get a clean replacement for each cat, then take the 'old water' fountains to be washed. The pumps are reliable, easy to change, and perform well. The design is a good one: the pump pushes the water up the 'tube' of the fountain to flow across the curved top; the fountain design includes a flower-petal insert for the tube, but both these cats seem to prefer that not be used ... they just like the water to trickle across the flat top. The pumps are a simple design, easy to take apart to rinse the inside. I'm VERY glad I found this type of fountain for them - and the water doesn't spill out; also, the cats can't tip it over (or maybe they just haven't tried?! :D ). Amazing such a small item could push that much water up an 8" tube.

Only one pump was delivered

Je ne voulais pas acheter une nouvelle fontaine puisque celle que j’ai est encore en très bon état, c’était seulement la pompe qui faisait défaut. Celle-ci a un débit réglable, ce qui est vraiment bien ! Relativement facile à nettoyer et silencieuse lorsque le débit n’est pas trop élevé. Je recommande.

at first it was noisy but it quit now

What I Like - A great replacement for my Catit fountain. It pushes the water up well. Easy enough to take apart and clean. A decent cost for a simple pump. What I Don’t Like - No LED light like the Catit pump to let me know it’s working.

Good replacement
