VIVOSUN 317GPH Aquarium Air Pump Commercial Air Pump with Aluminum Housing

For those that say it's loud, it may be because you have no stones or resistance attached to the outlet at that time. If you just plug it in to test it, it is loud, but with the stones attached and regulated, the hum is much less. It does get warm to the touch over time, but I do have a small computer fan gently blowing over it. I found that if you add a hose of the appropriate diameter to fit over the intake tube and about 12" in length, the hum is considerably less. The hose acts as a muffler on the intake side. It's now quieter than the 4 outlet air pump I had with WAY more air.

This pump is awesome. Heavy and well made. A little loud. But that is because of the power it has. I have 8 large air stones going most of the time and the bubble action is very strong on all of them I also have the smaller quieter version that works well but this one is a beast !

Product arrived in a totaled Amazon box, as they no longer back with air pockets. But the pump survived unscathed, even though clearly dropped. I also dropped it from 6ft high onto a hard floor when it toppled off the shelf while running, and it didn't phase it. Things to note: I wanted to modify this to use as a gentle vacuum pump. I was pleasantly surprised to find the plastic intake cover had a tight sealing rubber o-ring. No modification necessary, this is a mild vacuum pump out of the box. I plugged it in and it ran immediately, no power switch. Reliable and cheap. After placing a finger over the end, I determined it was a very low pressure pump, as the manufacturer stated. So I rigged up a suction tube to lift water out of a container on the floor. Placed the pump on the counter, and flipped it on. It immediately lifted the water and sucked in into the pump, and it shut down abruptly. Oh no! I ruined it... Nope. Poured water out of the pump itself, plugged it in another outlet and confirmed it worked just fine. It was the GFCI breaker that tripped. (They work too!). I then unplugged it and tipped it. More water came out! I had failed to dry it out completely from before! This pump; you almost cant destroy it! Now to test the vacuum by lifting water... Placed on a high shelf with a 10ft clear suction tube to the floor, over 6' of elevation. The pump pulled the water right to 46.5", subtract 2.75" remaining in the container for 43.5" wc (water column) of vacuum. This equates to 1.57psi, or 226lb/ft. ~ 10.8kPa of vacuum. (1,1m wc). This is a very good little pump. This was the basic lowly 15w. Higher power may produce better performance. I'm happy with this. 4.5 stars instead of 5, because they state it requires a 1/4" ID tube. This is 6.35mm, to the actual 8.0mm outlet diameter. You need a tube between 7-8mm to fit easily. Also, the suction input is 8.9mm; 10.25mm over the barbs. So you need a 9-10mm tube here. Blow: 9/32" to 5/16" Vac: 5/16" to 3/8" Get the 5/16" heat the tube to fit.

Huge volume of air flow! Can run Multiple Tanks

Absolutely great pump paired with a 4 in Vivosun nano bubble air disc quiet pump good for the price plug and play small size easy to use make sure to buy air tubing does not come with any

Works well

Way to loud and gets extremely hot the durability is good and the value is good but for thr noise it’s too much I get complaints from guest and family asking what the loud noise is

Maybe the best thing on Amazon, been running continuously for 2 1/2 years!!!

i see a lot of good reviews on this this is why i bought it. it Stopped working in less than 12h since i got it.

Built a homemade aeroponics system for growing plants and for rooting cuttings. It works great and produces lots of bubbles with the 6 air channels. It is in my garage so the noise does not bother me much, however you may consider this factor if it's positioned in your living area. I am assuming it could also be used for hydroponics systems

Great and powerful pump used it to make compost tea ?

Its excellent, price is right, but it is loud Its great for outdoor use.

Works great little loud but does alot of air output
