VIVOSUN 1600 GPH Submersible Water Pump, 100W Pond Pump, Ultra Quiet Aquarium Pump with 15FT. Lift Height for Pond, Waterfall, Fish Tank, Statuary, Hydroponic

The media could not be loaded. I installed our pondless waterfall in the fall of 2021. It's a great water feature for our front yard and we greatly enjoy having it. The pondless waterfall came as a kit which included an Aquasurge 2000 submersible pump rated at 2000 GPH.That pump, which I reviewed under "Aquasurge 2000" is a great pump. Unfortunately, in a little over 3 years of service I've now had two pumps go bad and, at a cost of over $300 it becomes an expensive maintenance cost.After many hours of research, I decided to give the Vivosun 3000 a chance. The waterfall has been out of service for a week and when the pump arrived today I got to work. the Vivosun 3000 is noticeably smaller than the Aquasurge 2000, so I was immediately skeptical that it would deliver 3000 GPH. But, it seems very well made and has a solid feel, so if it at least equaled the output of the pump I was replacing, I'd be happy.The discharge port on the Vivosun is the same size as on the Aquasurge, but sits 2-1/4" lower. The easy-enough fix was to fashion a stand-off, using spare PVC parts I had on hand. This raised the port to the same height as the Aquasurge, and made attaching the Vivosun to the waterfall supply line a "plug and play" replacement.After connecting the pump to the waterfall supply line, the moment of truth had arrived. Will the $75.00 Vivosun 3000 give at least the same performance as the much more expensive $320 Aquasurge 2000?I have to say, I was actually excited when I plugged the pump in and watched the waterfall come back to life!! And the answer to the question "Does it work and is it worth it" is a resounding YES!I don't have a way to measure the actual flow-rate, but the waterfall certainly is more robust than with the old pump. This was an easy replacement (with a few extra steps needed to build a riser platform). It performs wonderfully, and saved a good deal of $$ in the process.If this pump, running 12 hours a day, 24/7 on a timer as the old one did, lasts a year or more it will be well worth the cost. At this point I highy recommend this pump for my type of application. Good job Vivosun!

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.
