Matala Hakko HK150L Linear Air Pump for Ponds 12,000 Gallons+

Powerful Aeration for Big Water With the Matala HK150L Linear Air Pump

Struggling to keep a large pond or lake healthy and oxygenated? When your water is over 12,000 gallons, you need serious air moving from the bottom up. This pump pushes a huge column of bubbles skyward, pulling oxygen-starved water to the surface where it bursts into turbulence, circulation, and fresh oxygen. Rugged, dependable, and built to handle the weather, it keeps your ecosystem breathing year round.

Big Bubble Air Lift That Revives the Whole Water Column

The magic here is the air lift effect. By releasing a massive stream of bubbles from the bottom of your pond or lake, this pump does more than just add air:

• Lifts oxygen depleted water from the depths to the surface
• Creates tremendous surface turbulence as bubbles burst
• Drives strong circulation and aeration across the entire body of water
• Rated for ponds and lakes larger than 12,000 gallons

That constant movement helps prevent stagnation and keeps fish, plants, and beneficial bacteria thriving.

Air Flow and Pressure Performance of the HK150L

This pump delivers a strong 8.4 cfm (238 lpm) of maximum air flow, with performance rated at 0.20 bar (2.85 psi). As you can see from the flow curve, air output naturally tapers as depth and pressure rise, so you get a clear picture of what to expect at your working depth of up to 10 ft. Running at 145 watts, it balances big output with steady operation.

Built to Last Outdoors With a Weather Resistant Matala Hakko HK150L Air Pump

Placed poolside, pondside, or lakeside, this pump takes the elements in stride. Its cast aluminum body shrugs off the weather while keeping the internals protected.

• Very rugged and reliable for continuous duty
• Weather resistant construction for outdoor placement
• 1" OD outlet ready to connect to your air line
• 6.5 ft power cord for flexible positioning near your power source

Get the Right Setup for the Matala Hakko HK150L Pond Air Pump

Getting the most from your aeration system comes down to matching the pump to your tubing and depth. For the HK150L, the recommended tubing size is 1", with runs of less than 100 ft for best results. Pair it with a bottom diffuser to build that full column of rising bubbles, and position the pump above the water line in a dry, ventilated spot.

Regular maintenance keeps air flowing at peak levels. Replacement parts made for this model are available so you can service it without swapping the whole unit:

• Filter Pad for the HK150, 200, and 250 models
• Magnet Set for the HK100 and 150, noting the HK-M150 needs 2 sets
• Diaphragm Set for the HK150, 200, and 250

Swapping worn diaphragms and cleaning the filter pad on schedule keeps your aeration consistent and extends the life of the pump.

Matala HK150L Pond Aerator for Ponds and Lakes Over 12,000 Gallons

This is a high volume workhorse made for the biggest water. If your pond or lake tops 12,000 gallons, this pump has the muscle to circulate and oxygenate it from the bottom up. The result is cleaner, healthier water with the kind of surface movement smaller pumps simply cannot produce.
