Review on 🌊 Sun JVP Series 800 GPH Submersible Circulation Powerhead Pump - Set of 4 by Angel Caldwell

I selected them to install with a 54 gallon reservoir. It took me about 6 months to get to work and was initially happy with the pumps connected to a 2 channel wave generator (two pumps per channel). After about 10 days a pump failed and made a terrible grinding noise. I disabled that pump and left the other 3 running. Shortly after the Wavermaker started it, another pump started pounding for a few seconds. Two weeks ago I lost my third pump to grinding. I now have a working pump. It was a great idea, but I wouldn't recommend these pumps as a shaft generator. Maybe they would be fine for a steady flow.
