 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 pumps are compact, affordable, energy-efficient and very, very quiet (less than 38 decibels!)!
Hakko units utilize linear- motor theorem to reduce power consumption during full operation. Units are extremely quite 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.

Oxygen is the most important element for life. All life revolves around the availability of Oxygen. In aquatic environments like fish ponds, oxygen is the single most limiting factor for success. All aquatic life forms demand oxygen. From the fish down to the bacteria any body of water has what is called an “oxygen demand”.
Of all the essential elements in water, oxygen is also in the shortest supply.
Ponds and lakes gain oxygen in two ways:
- Photosynthesis by algae and plants.
- Atmospheric oxygen is transferred into water at the surface of pond.
Photosynthesis may produce sufficient oxygen for very low fish loads but is inconsistent due to the fact that at night algae and plants remove oxygen through the process of respiration. Most of the ponds and lakes we deal with have higher than natural fish loads and require additional oxygen to maintain a clean and healthy environment.
HAKKO air pumps can be used to create a huge column of bubbles or “air lift” rising from the bottom of a pond or lake. This brings oxygen depleted water to the surface where the bubbles burst and create tremendous surface turbulence, circulation and aeration. HAKKO air pumps used in this manner will literally breathe life into your pond or lake.
