VIVOSUN Commercial Air Pump 634GPH, 25W, 40L/min 6 Outlet for Aquarium and Hydroponic Systems

It's a great pump works. Well, it is loud, but if you put a hose from where the air sucks in it cuts the sound down a lot.

Decided to pick up the Vivosun Commercial 102W Aquarium air pump as my Higger aquarium air pumps kept slowly burning out. I needed a better-quality pump that could do the work of four Higger air pumps and last longer than 3 to 6 months. Since switching over to the Vivosun from the Higger pumps, I had no issues. The pump currently supplies air to four 18-inch bubble bars in my 450-gallon aquarium. The amount of air generated is impressive. All four bubble bars are running at with the valves wide open and there's still air to spare. Vivosun provides a generous 12 port manifold to allow for many connections from a single point. The pump is an impressive piece of equipment. Last thing to note, I created a video to do a noise demo. If you want to see the demonstration you can search in youtube the title of the video: VIVOSUN Aquarium Commercial Air Pump 1750 GPH 102W 110L/min 12 Outlet Noise Demo. In the video I stand about 6 or so feet from the aquarium before approaching it and opening the cabinet to show the difference in noise levels. What the audience is not aware of is I have already taken measures to lower the amount of noise being generated by the pump. I added a rubber mat underneath two 2x4s the Vivosun sits on dampening the noise quite a bit and currently bleeding off excess air. My plan in the near future is to see if I can further dampen the noise more by placing it in a Heavy-Duty container wrapped with noise absorbent/cancellation foam. My noise demonstration video on youtube. Just search on the title and you will see it: VIVOSUN Aquarium Commercial Air Pump 1750 GPH 102W 110L/min 12 Outlet Noise Demo **UPDATE 1/31/2023*** After switching to the Vivosun pump now for several weeks. I'm quite happy with its performance. I managed to lower the noise more by using noise cancelling foam which I wrapped the cabinet of the aquarium with on all sides. This also helped with various ambience noises such as the FX6 canister filters too. I would highly recommend this pump to anyone who needs a reliable and powerful air pump.

I got this air pump because the one I had was getting tired and not making enough air. When I set up the pump I connected all of the air lines I had been using to the manifold and turned the pump on. The pump makes a considerable amount more noise than my old pump, but I figured that was the cost of getting more air. What I did not realized until latter was how much vibration the pump creates. I have the pump in a room upstairs, I was in the dinning room below the room and can hear the pump vibrate the room upstairs. I hung the pump up to try and minimize the vibration but it still shakes the whole room upstairs. I guess that is the cost of getting 70 L or air per minute. Other reviews said the pump got hot, mine has run a couple days now and it gets warm to touch, but not hot enough to burn you. update May 2025- How do you rate something that basically performs the intended function of pumping a lot of air, but overall fails due to high level of vibration and noise. I used this pump for a couple months and finally could not take the vibration and noise. I had the pump upstairs in a family room and you could hear the pump and feel vibrations from this pump downstairs and though the house. I lived with it for a while, but it kept getting worse until I had to stop and try something else. The pump housing is very warn to the touch and does create a considerable amount of heat. It would probably be a great air pump for outside or if you have a very solid surface to set or mount it on.

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 pinch off their air supplies to only provide the air they need, but this pump isn't a pressure control pump, so it's going to run, regardless of how much air can flow. The better method is to bleed off the excess air you don't need. Take one of your 6 ports (or any other place you want install a bleed valve) and use that valve to bleed off the excess air. My method: 1. Connect all airlines and components you want. 2. Open any flow controls 100% 3. Open your bleed valve (either one of the 6 provided, or someone other valve) 100% 4. Turn on the Pjmp 5. Start to pinch off the Bleed Valve slowly until you get the air flow out of your connected devices. 6. Adjust any local flow valves as needed to balance out air between various components (i.e. Air Stones, Sponge Filters, etc.). 7. If needed close the bleed valve as required. There should be some air coming out the bleed valve, unless all your devices need 100% of the supplied air. 8. NOTE: If you have more air then you need, take your bleed air, and redirect it back at the pump, and use that excess air to help cool the pump. This will do two (2) things, keep your pump a little, cooler and reduce the load on the pump. If this helps, I would be curious to hear the results. I might make a Youtube Video, if I do, I'll come back end update this review. In the video, I try to contrast the air bubbles to the air pump, so give the pump noise a frame of reference.

Worked less than 10 mins

So my 4 valve air pump was barely working and I needed a replacement fast! I looked over the specs and feedback on several pumps and went with this one. So glad I did! Firstly, it is a mini air compressor, so oxiginating several resiviors (4 at the moment) is child's play to this beast. Allot of people said it is very loud, not so much. Mine is in the basement and cannot be heard upstairs at all. More than enough power for the 6 adjustable stainless steel valves, water is virtually boiling (not from heat lol) from the air delivery to the 4" stones currently in use. Could easily support larger air stones. The unit itself does get alittle warm, but not overly so considering the amount of force it creates. This pump is a definite must have for any hydroponic set-up! Arrived 2 days ahead of estimated delivery and in perfect condition, so A++ for that 😉 As far as the cost, that was a no brainer. Only a few dollars more than I paid for my other 4 valve pump, which didn't have near the power, died and only supported 2 buckets if run with a t (2 valves reduced to 1). All 6 stainless valves included with this unit can be adjusted very easily, which is nice because it really is that powerful! Heavy duty commercial quality!

This pump is very efficient, powerful and loud. I run a small aquaponics system with it. I hung it on bungee cords from the roof to limit vibration and it has been perfect for over a year. It pumps vast amounts of air and is self regulating so it only works hard when it needs to. Do not buy this for a living room aquarium as that is not what this pump is for. This pump would run 30 aquariums easily, maybe more. I run 4x12inch airstones that are over 2ft deep and it will violently froth the water without breaking a sweat. As you restrict the airflow, it turns itself down to conserve power (and noise) to match the load. It is very well made and I have not had to clean it yet. My room is a cool 60F and the pump is quite warm to the touch but not hot.

Very powerful can power my whole fish room. 180 75 75 90 no problems at all. Just a little noisy. But great air pump
