Driew USB Water Pump, Water Pump for Fountains Water Fountain Pump Submersible Water Pump 3W DC 3.5-9V 200L/H Black

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.

I purchased this water pump as a replacement for the one that quit working in my cat's water fountain. It worked perfectly and was easy to use and put in. It is still working fine to this day. It was cheaper than getting one at PetSmart.

Make sure to use the little notch to adjust the waterflow! It is located on the vents on the front of the unit. It is abit loud, im using it to replace a fountain pump on my catit pixie water fountain. But it isnt any louder than a quiet fan running or an air purifier. Works great so far.

The media could not be loaded. This is a small unit, it is not a powerful unit, but it works well for what I purchased it for: 1. Size, 2. Not too powerful, 3. Ability to power the unit without having to plug it into the wall socket using a simple phone charger.I’ve attached a video of the pump working. Although the water feature appears large, it is not. I’m using a small pot surrounded by small potted plants, staged on my coffee table. I wanted something cheap that would allow me to hear the sound of relaxing running water simply by drilling holes in a pot and saucer that I had already laying the house.Problems: The pump is very quiet. The only problems I encountered came from user error—water depth and flow intensity. The pump worked better when totally submerged under water. Also, the flow of the water can be adjusted by pushing the little tab in front of the pump from left or right. I have no intentions of running this pump 24 hours, seven days a week, and I don’t think any reasonable person would either, expecting a small cheap pump to last forever under those conditions.

Pump started making vibration noise after only two months of use, it’s louder than the original. I would often have to remove the Catit lid and give the pump a jiggle/bump to stop the noise. Now, at this point it has died! This is completely unacceptable and should last several years. Never buying this one again!

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.

Pump had low water pressure from the start, and it stopped working properly after 6 weeks. Do not recommend!

they do work if electricity isn`t available; all you need is a power source
