Hakko Air Pumps are high volume diaphragm pumps designed for a variety of low-pressure applications.

Koi pond aeration, large aquarium aeration and earth pond destratification are only a few of the many applications for Hakko pumps.

Hakko units utilize linear- motor theorem to reduce power consumption during full operation. Units are extremely quiet utilizing spectrum analysis technology in order to decrease any mechanical noise.

  • No oil needed for lubrication making the Hakko easy to maintain.
  • These are the best large air pumps available today.
  • 36 month warranty through the manufacturer.
  • Standard voltage is 110V.  220V is a special order with 2 month lead time.

Koi & Pond Tip of the Day
June 26th, 2017
The bacteria in a biological filter converts ammonia to nitrites and nitrites to nitrates. In a water garden with plants the nitrates are used by the plants. In a koi pond, or other pond with few or no plants, the nitrates just continue to build up in the water. Nitrate is far less toxic than ammonia or nitrites, but if allowed to build up for too long it will present problems. At least every 3 to 5 weeks a partial (about 10 to 20%) water change is needed to reduce nitrate levels in fish ponds.
