Features

  • SPECIFICATION - Model KP40 with a 25W motor, 635 GPH (40 LPM) flow rate, and 0.03 MPa (4.35 psi) air pressure. The motor has a full copper coil for high efficiency, low heat, and low power consumption. Delivers strong air output and pressure.
  • QUIET OPERATION - The pond aerator pump features multiple noise reduction designs for quiet running, including a sealed air chamber, rubber & silicone buffers, and a magnetic-driven diaphragm.
  • HEAT DISSIPATION - This pond bubbler features an enlarged housing surface that significantly improves heat dissipation efficiency. This design helps reduce the risk of overheating and extends the overall lifespan of the pump.
  • AIR MANIFOLD - Our pond air pump comes with an air manifold equipped with 8 outlets (3/16"). Simply connect it to your airline tubing and air stones (not included) for optimal oxygen distribution.
  • MULTI-PURPOSE - This versatile pump can function as a koi pond aerator (enhance oxygen supply for fish), a hydroponic air pump (aeration to stimulate root growth), or a septic air pump (boost waste decomposition).

  • First one didn't last very long but the company sent me a replacement and it has been working great!
Pattern Name: 635GPH
Update: After my bad review, the company reached out to me and send me a free replacement. This one is working great so I am changing my review score. I'm very happy with their support and the new unit! I would now recommend this product. Original Review: Worked great initially but just after the 30 day return period the pump suddenly dropped the output air pressure and was no longer usable with the air stones I have in my small pond. It was very quiet from the start but either I got a dud or these are not made very well. Also the air distribution adaptor is plastic garbage. It does not have any valves to block the air so you either need to use all the ports or find a way to block those you are not using. I do not recommend this product. ... show more

  • Needed an attachment to work
Pattern Name: 635GPH
It works great. It is extremely quiet and was so much less expensive than one from the plumber. My husband had it installed in 15 minutes and said it was so easy to install. We needed an attachment to help it connect because it had a power plug. Our system did not have an outlet. It is powerful and seems very durable. We are extremely happy with this purchase. ... show more

  • Broken, or just weak?
Pattern Name: 950GPH
Item I received doesn't pushout enough air to keep a little spot from freezing over. Guessing the item i received is defective. Would be nice to get sent a replacement.
