Gikfun 12V Adjustable Peristaltic Dosing Pump Liquid Metering Pump with Adapter for Aquarium Lab Analytical EK1960

So far so good! Actually it's perfect for my project/"invention". Not very loud at all. I can hear it when it's running at or near max speed, but it's still much quieter than the keyboard I'm typing on. At low to medium speeds it's almost silent. Provides a perfect range of adjustment when feeding two 18 gauge blunt tip needles. It can be dialed down low where they drip, or dialed up to where they shoot 3 foot long streams of water, or anywhere in between. I bought and received 2 more units, haven't had time to test them out, but will in the next day or two.

I bought this to does All For Reef for my aquarium while I was on vacation, but it worked so well I decided to just keep using it. I have it connected to a digital timer that gives me the ability to set H:M:S, so I turn it on for 13 seconds, twice a day, to get what I need. It's simple, easy to use, and consistent.

Very noisy and did not pump anything, not even air. Then I took it apart and noticed that the tubing was improperly installed, after I fixed it, it ran quieter, but still way too noisy. It did pull water 6 feet upwards in the tiny 2 mm ID tubing.

Seems to do the job, connected to an ATO sensor for my saltwater tank to top off with fresh water in the sump. So far so good, and does not seems to create a siphon, which is important since my fresh water reservoir is higher than the sump.

It worked well for a few months but the rod stopped rotating and the unit no longer worked. Reached out to the company and never got a response. Tried to repair but the unit is made so cheap it would likely be cheaper to just buy a new unit. I think I’ll just bite the bullet and purchase one of the fancy $200+ units that will last for years. Worth a try but ultimately these units are not designed for longevity. $30 down the drain…

Sorry, but this pump didn't work at all, it wouldn't even lift water out of a cup. I tried it in several orientations and with the water supply both above and below the pump itself and I could never get anything out of it but occasional drips. I pre-primed the pump and it still wouldn't pull water up or push water out of the discharge side regardless of motor speed. It was running for about 3 minutes while I was trying to get it to work and motor or pump started to sound very labored. I turned it off and let it sit for a while, then tried it again. The motor turns, the pump sound like it's turning, but it will not pump anything, not even water and not even when it's pre-primed. I notice the product reviews seem to be split between people who say it works and those who say it doesn't. Sadly, I'm in the latter category; I don't know if this is a quality control issue or what but this simply did not work for me. As such, I'm hard-pressed to recommend it but who knows, maybe it'll work perfectly for you. (??)

Works as expected, a bit noisy, but nothing wrong.

Uses it with some printed parts to make a device to empty resin from my 3d printer vat. Works great and I don't have to remove and tilt vat, risking spilling resin.

Excellent simple does what it was designed to do .

Ha la spina americana, inutilizzabile con le prese italiane se non con ulteriore adattatore. Reso
