Una excelente marca,y he visto el crecimiento de mis tilapias

I bought this in March 2024, over a year ago and it's still running great. Even kept it running throughout the winter. The one issue was, when I attached a filter hose line to the thread intake, the casing broke. Doesn't appear overally strong, so I don't use an external filter but it doesn't appear to need one. I would buy this pump again without hesitation.

So far, this has been the best pond pump we’ve owned. It’s worth the extra few dollars. It doesn’t have as many attachments and there is no sponge filter however it clears the pond water. I’ve had to remove it when it’s gotten colder and put it back in when it’s stayed warmer and I’ve been amazed at how quickly it clears the water. We’ll see when summer rolls around and it’s running most of the time but overall I’ve been very pleased.

Update: Awful! One month after installation the pump failed completely. Motor seized, locked in place. My similar Little Giant pump has been running for ten years straight now, 8 months a year, in Southern Wisconsin. I had to replace my 880 gallon fountain pump, so I purchased the Vivosun 1600 gph PG1600-S. I installed the pump and plugged it in, assuming the flow might be overwhelming. To my surprise, the flow was less than my previous 880 gph pump. That's fine for me, because it looks good. Out of curiosity, I decided to measure the flow. I have a 3 foot pipe (head), which I routed directly into a 5 gallon bucket without a restriction at the top of the pipe. It took exactly 61 seconds to fill the bucket. Simple math says that is roughly 300 gallons per hour. The manual suggests it should be 1189 gallons per hour for a 3.3' vertical rise using 3/4" tube/pipe. Yes, I used an adapter to reduce down to a 5/8" inside diameter pipe, and that would reduce total flow, but it should also increase pressure at the end of the pipe. Instead, the water only gurgles about 1" above the 5/8" pipe. In conclusion, although it works fine for my application (see video), I strongly stand behind the other reviewers who are saying the product does not meet its specification. Also, someone needs to send a spell checker to the Vivosun Technical Writing team, or teach them how to spell fountain. That's just embarrassing. Now let's see how long it runs. All things considered, I am very concerned. My 2 star rating reflects it. I'll update the review over time.

Great pump works great and very well built.
