Hakko Linear Air Pump
Industrial-grade linear diaphragm air pumps — oil-free, quiet and rebuildable. The backbone of pond and lake aeration, driving diffusers that oxygenate the whole water column for healthier fish and cleaner water.
Oxygen first
Oxygen is the #1 limiting factor for pond health. Bottom aeration circulates and oxygenates from the floor up.
Quiet & efficient
Low-wattage linear motors run cool and quiet, 24/7, for years.
Rebuildable
Diaphragms and magnets are replaceable — refresh the pump instead of replacing it.

Install it right
Mount the pump at least 2 inches above water level in a dry, ventilated spot — a flooded pump voids the warranty (don't rely on a check valve alone). Pair with weighted hose and a self-weighted diffuser, or buy the matched MEA Pro kit.
