VIVOSUN 4500GPH Sub Water Pump for Pond Waterfall, Statuary, Hydroponics

Not paid - no benefits given, I just needed a good submersible pond pump - and this one delivers. Started using the VIVOSUN 4500 Submersible Water Pump for my pond, and I must say, it has exceeded all my expectations. This pump is a solid construction powerhouse with a range of features that make it stand out among the competition. One of the standout qualities of this pump is its exceptional construction. I can definitely see how the silicon carbide material used for the shaft and drive ring will extend service life. The VIVOSUN 4500 is an energy-saving champion with low noise levels. Its ultra-quiet operation, with only 30-40 decibels of noise, is truly impressive. Furthermore, it consumes less power (220W) while still delivering an outstanding output of 4500GPH/17000LPH, surpassing many other pumps in its class. With this pump, I can enjoy a powerful water flow in my 2000-gallon pond without worrying about excessive energy consumption or noise disturbance. The high lift capability of this pump is simply remarkable. It can reach a lift height of up to 19FT/5.8M, allowing me to set up beautiful water features and fountains that demand elevation. The convenience of the portable handle and detachable filter makes maintenance a breeze, ensuring a clean and efficient water circulation system. Installation was a breeze, thanks to the adjustable outlet direction and a 20.3FT power cord, which provided flexibility and ease of use. The pump's compatibility with different tube sizes (1 1/4” or 1 1/2” internal diameter) and its ability to work seamlessly with filters makes it an ideal choice for various setups, whether it's submersible or inline use. The VIVOSUN 4500 is genuinely a multipurpose workhorse. I highly recommend the VIVOSUN 4500 Submersible Water Pump to all pond and water feature enthusiasts. Its solid construction, energy-saving features, and high lift capability make it a standout performer in its class. Whether you need a reliable pump for a pond, fish tank, fountain, or any water-based application, this pump will not disappoint. VIVOSUN has truly created a remarkable product that has made managing my aquatic setups a joy.

Been using these pumps for about five years now I’m very pleased with the performance. Don’t forget to clean the impeller. That was my error so I needed to buy a new one but very affordable.

Really a nice & powerful pump, perfect for my small frog waterfall & pond. Easy to install too.

Update 7/13/2021: i ordered another one as my pump all the sudden stopped spinning again. i remembered to try cleaning it again like back in 2020 and this thing is working like a champ again. Love this pump. Keeping the new order as a back up for when cleaning no longer works. Ive been using this pump since july 2019 , about 10 months now. It seemed to stop working may 11th 2020 as the fan stopped spinning when it was plugged in. Fortunatley I was able to remedy it by removing the fan and cleaning out the magnet housing inside which looked to be caked up with built up film, using a tooth brush. It is a little tricky to unlock the fan from its housing, you will need a flat screw driver something to lightly hammer the screw driver and something to wedge inbetween the screw driver and the point that locks in the fan. In addition, i messaged vivosun and they graciously offered me a solution to either refund or replace the product at no cost to me. I have to say that was very nice of them on their part. Fortunately I didnt have to take them up on their offer so kudos to them for customer service. The pump i purchased was the 4500gph version which they do not have listed anymore but i would venture to say that the higher and lower units are both probably good and worth the try and value. The 4500gph is really strong, i did no testing to show the output is actually 4500gph since well I dont know how. But, i can say it flips my 1700gallon fish pond over rather well causing enough flow that my pond stays clear. The flow was so much that i had to add two diy overflow 2" pipes to a 1 1/2 and 2" pipe outlets for the return. This thing easilly shoots up water 4' off the ground. The intake fans seem to be designed in away that algae/debrie does not clog up on it or at least i havent had that issue as of yet. However the cover to the fans can get clogged if its not ventilated well for flow or if the debri is too big and cakes up around the entire inlet casing. As i mentioned earlier, the fan can stop if film from debrie and water minerals forms a film on the inside of the motor and the fan magnet itself. in the inside of the magnet housing the fan rests in. My only consistent complaint i have about this pump as another customer has mentioned is the inlet cover that protects the fan. It is loose and can come off if not secured in some way. It does not lock well in its current design. I use pvc piping to connect to the outlet on the cover and secure rhe cover from coming off by usinf large stones inside a bucket that holds the fan in place. The pvc piping basically gets hold by the stones which inturn keeps the cover from moving. Im sure one can find other clever ways to keep it on. This pump can take either hosing or pvc piping, which us great because i prefer pvc over hoses for this thing. Also the pvc connectors can easilly be found at home depot. There are a few options to connect it, i used a threaded coupler with smooth end to attach pvc. I forgot what size but it shouldnt be too hard to figure it out. I would recommend anyone to try vivosuns models of this type of pump. The cost and effeciency is worth it. I do not believe my pump stopping due to the film build up was a defective reason and more of a wear and tear cause so well see as i continue to use the one i currently have.

August 31, 2020-30 days later. I use it when I'm on my deck so approximately 2 to 4 hours a day. It runs well and is very quiet. 4500 is a lot of water; I added a flow nozzle to restrict flow and that's worked well. I got the pump on August 1, 2020. It's been a week and I have no idea how long it will last. I run it when I'm at my pond, but not any other time; that will add to the time it last. The nose is supposed to be adjustable. This pump is NOT adjustable. You can remove the nose cone to clean it, but not change the direction of flow. I tried and the unit pushed nothing; it's meant for one direction-up. I'm disappointed about it, because I did not want to see the hose sticking up above the water line like the lock ness monster's hump! Haha, but the pump pushes a lot of water and I'm glad I went higher for flow and not lower. This pump is not a trickle pump. It pumps water as much as my garden hose on full. Very pleased with the GPH.

So far so good. I'll definitely update if I have any issues. This replaced my second pondmaster proline hy-drive 4800. They seem to last about 6 years. It's $481 and 280watts. This is $90 and 220watts. At a 6 foot head, this supposedly pushes more water, but honestly, I can't tell. Even if I have to replace this pump every 3 years as some have experienced, it'll still be half as expensive as the pondmaster. Plus, I'll save a few bucks on electricity.

Bought this pump for use in my 3 tier bassalt rock tower fountain with the towers approx 4’,3’, and 2’ tall. The 4500 gph flows great with the control valves almost fully open. Runs quiet and is great so far!

This is absolutely ridiculous. I purchased this pump (end of March 2022) and didn't install it until spring (May 2022) because we go through a hard winter here. The pump only lasted about 2 months and it failed. I was sent a new pump in July, July 7th I believe it was and today on August 26th the brand new pump failed! This is absolutely ridiculous, this piece of junk should be taken off the market. My pond Boss pump is still going strong 3 years now. My water clarity is perfect, this pump was in its protective mesh bag and my pumps do not sit on the bottom of my pond. Bottom line is this is a piece of junk!

very happy with purchase perfect size for my 5000 gallon filter

ya la conectaste el mismo dia e BINGO....functione de maravilla con mucho potente. est si sube a 4 metros facil. el chorro de agua esta muy fuerte a 3 metros de altura excelente producto

Perfect for my 18' pond.

Efficient an easy to install. It replaces a pump of similar capacity but seems to perform better.
