Alpine Corporation 4000 GPH Submersible Pump with 33 Ft Cord for Ponds, Fountains, Waterfalls, and Outdoor Water Features, 306W Quiet Motor, 21 Ft Lift, Multi-Angle Flow, Blue

We’ve been using Alpine products for years, including the Cyclone pond pump, and I continue to be impressed by both the quality of their products and the level of customer service they provide. Recently, I had a small issue with the pump and Alpine’s customer support was absolutely outstanding. They responded quickly, were professional and courteous, and followed up several times to make sure the issue was completely resolved. The company truly stands behind their products and went above and beyond to ensure I was satisfied. It’s rare to find a company that combines great engineering with genuine customer care. Alpine is one of those companies, and that’s why I’ll continue to buy their products and recommend them to others without hesitation. Five stars all the way! Quality products, excellent performance, and the best support team you’ll find anywhere!

Would I buy it again? Absolutely! This being my second PAL 5200 Submersible Pump from Alpine Corporation in the past 14 years, I am very pleased with my choice and this product. This pump meets the product descriptions given by the manufacture as selling points to purchase this pump, or a like pump from Alpine. The pump is compact, sturdy, and for as long as they have run, I would say well designed. The pump has performed quite satisfactorily producing the power, flow, and lift that I was needing for 3 fountains, while operating very quietly, almost unheard (it is submerged)! Although a relatively clean pond, deer and birds drink from the raised fountains and leave behind their residual effects which pose no problems for the pump. With heavy minerals in our well water (Hard Water), I surmise that my first pump froze up due to a mineral build-up; otherwise, it is likely the pump would still be running. Having had an issue with my pump, I did contact Alpine Corporation’s Customer Service. Their staff, and especially Ms. Delima, have been extremely helpful and considerate. After providing them with pictures and receipt of past purchase, they have responded quickly, professionally, and with consideration for my dilemma. The fact that you can reach someone at Alpine Pumps (email exchange) is reason alone to use their pumps! Great product!

Alpine stood behind their warranty. I purchased the Alpine 4000 pump in September of 2023, and one day this Spring, it just stopped working. I liked the pump - it was quiet, easy to operate and keep clean, and had an incredibly long cord, The flow rate was more than adequate for my recirculating waterfall. Knowing that the pump was still under warranty- I reached out to Alpine for help. They were responsive and very graciously sent me a brand new replacement! I’m hoping to get many more months of use from the new one. It does its job well. Thank you Alpine!

This is the best pump I've ever had. I've had probably 15 pumps over the years and this one has gone very strong. 6 years later and it's still running strong. Sometimes it even sucks in air for an extended period and it still works okay. So I'm very happy with it

We bought this pump for our Pond in Oct 2021, and it worked great for almost 3 years, with no problems --until a month ago when it stopped working out of the blue. Alpine gives a 3 year warranty on their product, and since it was still under warranty, I filed a claim. I have to say that I haven't encountered such a professional Company like Alpine in a very long time. I say this because of the top notch manner in which Alpine Customer Service (Karen) handled my claim. The whole process was easy to do online, and Alpine responded very quickly to my emails and claim. Within less than 2 weeks ( most of due to my delay) I received word that Alpine would be sending me a BRAND NEW PUMP! ( all I had to do was pay $25 for the shipping! So the bottom line is, I'll always buy Alpine products in the future, because I now TRUST Alpine will honor their warranty commitment, and stand behind their products. It was a good pump, that worked great for me for almost 3 years.

Want to amend my original review (posted below): after contacting the company (Alpine), they were exceptional at understanding my situation and promptly sending me a replacement pump, free of any charge. I was also permitted to keep the dead pump for replacement parts, instead of sending it back. This has been hugely appreciated! The pic I've uploaded shows the replacement pump in action as I'm filling the pond back up after a couple weeks of neglect since the original pump died. We purchased this pump to have a little extra flow in our small backyard waterfall/pond. It did an excellent job, providing exactly the amount of water flowing in the waterfall that we were seeking. HOWEVER, TWO MAJOR CONCERNS: 1.) It's extremely underpowered; for 5200 GPH, it works more like a pump that does 2,500 GPH. Then again, we didn't like the flow rate from a competing pump company, so we went to a higher GPH to get us the flow we were seeking - - it did meet that need. 2.) Three weeks in, I walked out to find it completely DEAD. No life. No signs of life. Nothing. We liked the flow so much that we returned the dead one to Amazon, and ordered a replacement. Here's to it working for many YEARS, not WEEKS.

I have purchased my first pump approximately 5 years ago and it ran 24/7 including hurricanes with no issues until the pump finally stopped working. I purchase a second one which ran only for a couple of months and and I contacted customer service at Alpine and they immediately got back in touch with me via email. They were completely helpful and help solve my problem. They sent me a new pump after explaining to them the issue that I was having. I only had to pay shipping and handling. I also found after the original emails that were sent to me on how to maintain the pump to increase lifespan, I was actually able to get my original pump back up and running. The customer service was outstanding and the product arrived in just a couple of days. I would definitely recommend this pump especially due to the type of fittings that it has on the intake and the output side bolt which are able to accept PVC fittings. This makes it so that I could use it for multiple different types of applications especially by putting different types of fittings on the end of the PVC pipe so that I can either create a wide Fountain effect or a 20 ft High geyser. Just add some color for lights to it and you got a resort in your backyard.

I’ve never taken the time to do a product review, but wanted to share my experience with Alpine and their pumps. A year and a half ago I ordered the Alpine 5200GPH cyclone pump to supply water to the shower filter in my 5,000 gallon Koi pond. I was very impressed with the quality of the pump when I received it and the ease with which I was able to install it. The pump worked flawlessly for 1 1/2 years and actually exceeded my expectations in the way it performed. Almost two weeks ago now it suddenly quit working. Given the number of Koi I have the pump is critical to helping maintain water quality and I was concerned about the impact of the pump being down. I followed Alpine’s simple instructions for checking and cleaning the filter and impeller, but the pump would not respond. Worried about my Koi I immediately called Alpine to discuss and spoke with Grace in customer service. I don’t think I’ve ever received such professional, courteous and responsive customer service as I did with Alpine and Grace. It was absolutely a best in class response and experience. I explained the problem with my pump, which was still under warranty, and with just a few pieces of information required from me they immediately assured me they would take care of my problem. Within just a few days I received my new replacement pump and had it working well in the pond. I have complete confidence in Alpine’s products and willingness to stand behind them. They are the best and I’ll always come back to them !!!
