Air Pumps for Hydroponics

What is hydroponics?

Hydroponics is the technique of growing plants in nutrient enriched water instead of soil.  The nutrient solution (includes such minerals as phosphorous, magnesium, nitrogen, and potassium) is recirculated in a closed loop system. 

What are the benefits of hydroponics?

  • High yield: hydroponics yields more calories per square foot.  Plants can be placed closer together allowing for more plants or a smaller growing area
  • Since hydroponics systems can be installed indoors, plants can grow in any climate throughout all seasons
  • Hydroponics uses 90-95% less water than traditional farming methods because there is little evaporation and water is re-circulated in a closed loop system
  • Vegetables tend to grow 25-50% faster than in conventional farming methods.  Plants grow up faster because there is less of a root system
  • Hydroponics does not rely on pesticides and is environmentally friendly
  • There are no weeds, less pests, and less disease than conventional farming


Linear diaphragm air pumps have been used for hydroponics for years.  The design is built for 24/7, 365-day use and is lubrication and oil free.  The pumps are energy efficient running on less electricity than an incandescent light bulb.  Perhaps the greatest advantage of a quality linear diaphragm pump is that it is very quiet compared to most rotary style aerators. 

HIBLOW Advantage:

HIBLOW invented the linear diaphragm air pump back in 1968 and is the gold standard.  Most models run on 70 watts or less with a noise level below 40 dBa.  HIBLOW pumps use only a few moving parts and therefore can be easily rebuilt in 20 minutes or less.  With 2 rebuilds, the aerators can continuously run for up to 10-15 years (depending on the system pressure and model size).  HIBLOW offers 3 different series (WG, XP, HP) with flow rates ranging from 20LPM up to 200 LPM.
