Alpine CorporationEco-Sphere Energy-Saving 5400GPH Pond Pump with Controller and 33-ft. Cord

I built a 30' pondless waterfall and stream with an 7-foot head. It has 8000 lbs of basalt rock and river rock, blue/green lighting, automatic irrigation for the surrounding garden, a little bridge, etc. It was a big investment in time and money.When it came to selecting a pump, I wasn't sure what flow rate would be ideal. Would I want high flow and loud? Or a very low flow that is quiet and calming?I also was concerned about energy use. I found some pumps that burned 400W of power. The electricity bill to run these pumps 24/7 would be significant.I created a spreadsheet in excel and listed over a dozen different top rated pumps from various manufacturers. When I found this Alpine pump, it immediately stood out as the best.I've run it only for a week now, so I can't comment on its durability and reliability. But, after turning it on and experimenting with it, I am very surprised by three discoveries:1. At 100% power, the flow rate is amazing. It's like I have a little Niagra Falls running. The waterfalls are loud and turbulent. But the calm, lower-flow setting of 33% is preferred by family members. It's quiet and calming. I love the variable speed controller! Why would you settle for a pump that doesn't have variable speed? Most days I want quiet, but some days I want loud and bold waterfalls.2. At 100% power, the power usage is only around 160W. But at my preferred 33% setting, it's only 30W!!!!!! Wow! This waterfall is costing me next to nothing to operate due to the high efficiency motor!3. I didn't realize that the controller has a digital 0-100% setting that SWITCHES to a watt meter after you make your flow rate percentage selection. I love the built in watt meter! I measured it against a dedicated watt meter that I own and it's spot-on accurate.All in all, assuming this pump is durable, it's the one to buy.ADDED May 2, 2022... After 4 years of near continuous use, this pump is still going strong. I've had zero problems with it.ADDED Nov 28, 2023... Pump still going strong.

I bought the 5400 gph pump a little over a year ago for use as the main water mover for our ~5000 gallons gold fish/koi pond . The pump and controller has been on almost 24/7 ever since without any issues . My pond is next to a live oak so I did have to clean out leaves/roots stuck on the propeller twice . The pump works very well , even with the propeller fully clogged it was still moving water .About a week and half ago a thunderstorm rolled through our area . Lightning struck my neighbor's tree . I came out after to find the pump not running . There was a smell of burned plastic around the controller so I opened it up and the PCB was charred at one corner . I called customer service the next day and was connected right away . After hearing what I have to say , the rep told me the pump was still under warranty and they will honor it . I got the email the day after with instructions to provide pictures of damage and verify my purchase . And before the week was out I paid $15 for shipping . Fedex delivered the replacement today . I only wanted the controller replaced but Alpine sent me the whole set . Thank you so much .

When I purchased this product it was because I had read so much about the great customer service if there was a problem with it. Well, unfortunately, I did have a problem with it but after a few emails and a call, the problem was corrected immediately all I can say is if you buy this product and for some reason you have a problem with it they were more than happy to take care of you. So if you ask me, this is a really good product with a great warranty and great customer service.

If you are looking for a powerful pump that will only last a year, this is your product! I bought two that replaced a much cheaper pump that lasted 5 years. This is not a quality product or company!

Arrived packaged well and in a timely manner. Only reason I gave it 4 stars is it quit after two months use. Only reason I gave it 4 starts instead of 3 is because the seller was tremendous to work with in receiving a replacement pump. The pump is quiet as can be and can't even hear it run. Quite powerful and like the flow adjustability. Would definitely recommend to others and will use this brand if my wife insists on more water features.

I had a waterfall and small pond installed in my yard in 2014. I loved it, but I hated that it added $30 to my power bill every month. I know that doesn't sound like much but my power bill had never crossed over $45 a month prior to that. Had the landscaper told me about the power consumption I would have looked for one more energy efficient. after 3 years of it I decided it was time to look for another pump. after searching online i decided to try this one. There were a few different sizes and I decided to go with the 5400 gph model as I heard it wasn't as powerful going up a grade. That is true. It is definitely not as strong as my Little Giant 4000 gph pump, but way more energy efficient. My power bill dropped by about $24 a month. The waterflow is probably about 80 -85% of what it used to be on the little giant pump, but it is still plenty. if you have a tall waterfall, this pump is not the one for you, but mine in probably about 5 ft tall and it does plenty. I also appreciate that the cage makes it easy to clean the leaves around it. I run this 24 hours a day 365 days a year and it does fantastic.
