I am in the process of enlarging my outdoor pond and I am told that I need to get a larger pump, 5000 gph or larger. Can anyone recommend a name brand that has a good warranty and low electrical usage?
Perhaps a Floating Aerator Fountain. Kasco makes a 1/4 h.p. one. I think it's about 5,000 gph. And, you can find smaller ones as well as other brands. Then just keep your smaller pump as well. My pond is 40x40x5 and a 1/2 h.p. is recommended. The wattage here is @ 300.
My company has had excellent luck with Tsurumi brand pumps. We've had clients run them dry when they were gone over the weekend. The pump still worked like a champ after water was added. Good units!
tsurumi pumps are the way to go! but if you can find one that is magnetic driven instead of direct drive, the pump will pay for itself over time wow you must have a big pond in order to need a 5000 gph, I am gueesing 10,000 gallons plus or you're pushing a high lift waterfall
