1/2 HP Rocking Piston Pond Aerator Pump, 3.9 CFM 120V Electric Compressor

I bought this in 2021 and it's been running nonstop ever since. 20 ft deep on a 100 ft weighted airline. Just keep the unit out of the elements and intake filter clean. I clean mine every other month and have had zero issues. Highly recommended.

Very reliable Aerator the quality is good and very Durable It is the second one I’ve have gotten I would buy again

When my original aeration pump failed, I was shocked to find the cost was nearly that of the full system. After some research, I picked this pump. It is smaller dimensionally and required some creative engineering to fit into the old box and connect to the distribution piping, but not terrible. Picked up a few pipe fittings and modified the old plumbing. My main complaint is the use of 1/4" 24 threads in the base - it is nearly impossible to find these threads on bolts today. The pump is working very well after two weeks of continuous operation. It is actually quieter than the original pump. I am very satisfied with it.

Overall very happy with the aerator pump. I had an issue with the pump being a little loud after a couple months. I informed them of the situation. They sent a new one immediately. The aerator pump helped make a remarkable improvement to my pond that’s was overrun with duckweed. In my experience their customer service was very help and prompt. I would buy again without question.

Purchased and installed pump in July 2022. The aerator froze up on 20 march 2023. Contacted customer service in the morning and they had a replacement aerator shipped to me that afternoon! Received the replacement aerator 2 days after the other one quit!

Purchased this pump in Aug 2024 to replace a previous version of this same pump originally purchased in 2020 as part of a stock pond aeration kit as the diaphragms had worn out and replacement parts could not be found. The motor on this pump burned out after 14 months. I had kept the 2020 pump and attempted to re-use the diaphragms from pump, but the design had changed and was not backward compatible. This newer pump seemed to be built with cheaper parts and less durable than the prior pump. I will no longer buy from this brand. Swapped out to a Hiblow pump like what is used on my septic system, which is re-buildable and has parts readily available.

Bought an aerator kit with the single cylinder compressor kit and fought with the pump for a year before giving up and order this one. First - it's MUCH quieter than the small single pump (which it looks a lot like). I went ahead and zip tied all the wiring to fixed parts of the motor so it wouldn't vibrate (which is what destroyed the wiring harness in the smaller pump) - not totally sure that was necessary since this pump has much less vibration overall.

I have been using this pump in my pond for many years now, and it has worked flawlessly. Thanks for a great product!
