VIVOSUN 317-1750GPH Commercial-Grade Air Pump

customer: This little pump really works great. Finally my air stones work like there supposed to. Does get a little hot so it needs room to breathe so it doesn’t over heat.

Kindle Customer: As others have said, it is loud, but it is effective. Mine runs in unoccupied space so noise is not an issue, that said, probably not the right choice for a family room.

charles alabaster: Really easy to setup. Pumps great amounts of air. It’s heavy and is sturdy and strong like bull. It looks like a bulldog slobbering on a bone. I think there is a high value in the aspect ratio of dollars spent to dolphins acquired. I still think it’s worth while remembering how incredibly loud this air pump is. No chance of this in your house, it’s barely tolerable outside the house. It provides equal air to noise ratio and it’s got plenty of each.

Amazon CustomerAmazon Customer: This is a great little pump but it has a critical flaw that is dangerous. The issue is the strain-relief connector for the electrical. (**as noted by other reviewers**). The constant vibration of the pump is enough that the wires fatigue and break. If you look at the two pics i posted, you will see bare copper wire which is, in this case, the ground wire. This wire was not only exposed, but was broke completely through. This creates a situation where a person could be injured or killed by electrical shock, or possibly start a fire.

Having said that, it is an issue that manufacturing must address.

As for how well the pump works, well it’s great. I ran it 24/7 for 32 weeks. It moves air very well and has had no problems (other than the safety issue). I replaced this pump with another of the same. The noise is a bit louder than some people would like, so it’s important to keep location in mind. I found the noise and vibration frequency has an ability to really resonate throughout the house. And yes, this little air pump does get warm but it’s not enough to burn your fingers when you touch it.

Knowing what i know now, i’ll be sure to keep a close eye on...

Human Error: I expected so much more from an air pump boasting 50W of power and 1110 GPH airflow. The first thing I noticed when I initially hooked it up, is how hot it gets, including the nozzle the air hose connects with. I used this pump in a 6 pot hydroponic RDWC Root Sprayer setup, with 2 air stones in the pump tank, and one airstone each per 5 gallon pot. This pump had great airflow, while it worked. This pump becomes very noisy within a year, and died within 6 months after. The Vivosun pump ran so hot, it melted the tube to the nozzle which in my opinion, makes this thing a fire hazard I really wanted to love this pump for the price/airflow rating, but longevity was very lacking. I can't have a pump possibly burning my home down. I also need a pump to be able to run 24/7/365.

In fairness, I bought a second pump from Vivosun, just in case I just had a bad one, hopefully, the second one will last longer. I still have an Active Aqua pump that is still quiet, and still running, and they were both bought at the same time. For the money being asked, I would expect a pump to last much longer. It is clear the integrated cooling design is incapable of dispersing adequate heat to keep the...

Eric KirchnerEric Kirchner: The media could not be loaded.  So, I was not happy with this at first. Did a LOT of googling and YouTube searching. I now have a nice quite pump, and the fix was actually pretty easy. I don't have a video of how loud it was at first, as the noise came and went, but I have included a final video. What I did should only take about 10 minutes a screwdriver, and some PTFE Thread Tape.

1. Tighten all screws (NOTE: it seemed to me all the holes in the aluminum casting where a bit sloppy, so I loaded each external screw with Teflon Tape, and reinstalled them).
2. Add Teflon Tape to the Brass nozzle barb (that also felt loose to me).
3. Remove the Rear Air Filter, and the 4 screws holding the Piston in place (See Picture).
4. Wrap some Teflon Tape around the ball bearing installed. It seemed to me this was where the rattle was coming from. I think the bearing is a little small, or there is more slope in the holes than needed. This cause a slight harmonic rattle.
5. Wrap tape (optional) on the screws holding both the rear plate and the air filter housing, and reinstall.
6. Run your pump and see if the rattle goes away.

A couple notes, most people seem to...

Amazon Customer: The problem I see which is so minimal is I would suggest 2 hose clamps, my hose blew off a couple times $0.20 later back in action. Thankfully I caught it before it was too late but the plants were droopping from lack of oxygen.

Using it for my hydro I have 2 valves wide open and 4 with bubblers and it's great as long as it doesn't burn out.

It sure does get hot so I hope it doesn't melt out the seals, but we were told about that in the ad. Also anything that makes air makes noise deal with it lol, it does have mounting bolts mount it with rubber no noise. Or like someone said hang it, then less issues from heat and no noise. If you want a quiet one get a fish tank bubbler.
I deal with 440volt electric motors that are fan cooled that get this warm so I'm sure the heat won't be a concern. But pretty easy to implement a cooling fan on the back side for the little bit it would help.

Just please some hose clamps these should be included at least with the 50watt 1100gph pump can't speak for the others.
