          Great product, company and employees
          Pump failed after about a month, but the extremely friendly and helpful customer service/support are shipping a replacement. I have purchased several of these pumps and will continue to do so.

            Beautiful Fountain
            I made this fountain using the Alpine 8000 GPH pump. It’s very powerful and has a great flow rate creating a beautiful shower. Very simple to install and maintain. Recently had some issues with the pump and I reached out to Alpine Corporation for assistance. Within a few days they had sent out a brand new pump without hesitation. Their customer service department is outstanding .

              waterfall flowing
              Worked great as soon as i installed it. Recently stopped working and Alpine is sending a new unit to replace it just in time for the koi to get fed again. Great pump and Alpine stands behind their product!!!

                This thing is powerful!
                We bought this pump to be ran non submersed for our approximately 10,000 gallon pond! This thing is very powerful, we run about 20 feet across and about 3 foot high to a waterfall. We are glad we went with the 6550 over the 5200.

                    love these pumps!
                    When I built my 7500 gallon pond I received some bad advice on which submersible pumps to use for my outside waterfalls and installed Shimwaywa 1100w 7000gph pumps. They worked great but my electric bill was almost $500/month!! After doing some research on my own I replaced both of those pumps with these Alpine Cyclone PAL8000's and am thrilled with not only the performance of the pumps but with how much money I'm saving! These pumps cost 1/3 of the price to purchase and are saving me about $200+/month in electric usage! These Alpines are giving me the same throughput to the waterfalls as the expensive Shimwaywa pumps were for a fraction of the price! The pumps are 540 watts and are magnetic drive pumps that are the most energy efficient type of pump that you can buy. I've attached pictures, the two Alpine pumps are connected to the two outside waterfalls and I have an external Helix pump going to the middle waterfall. I'm running 2in flex PVC pipe to each waterfall which allows a maximum of 5000gph.

                      Just shocked at the volume of water that this pump handles. I replaced the pump in my waterfall with this Alpine PAL 10300 and what a difference from an external pump of the same price.
