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!)!
