Hiblow HP-150 Applications

The Hiblow HP-150 linear septic air pump is commonly used on many 1000 GPD and 1500 GPD rated NSF Class 1 Standard 40 aerobic treatment systems (ATUs). The Hiblow linear diaphragm septic air pumps are widely regarded as the highest quality and longest lasting septic air pumps available on the market. They are extremely quiet and very energy efficient. The Hiblow HP-150 can be used for septic tank aeration as well as an aerator for small ponds.


The septic air pump is literally the lifeline of your aerobic system. The system cannot function the way it was designed without the air pump working. The actual purpose of the air pump is two-fold. First, the air pump puts oxygen into the water allowing the formation and survival of Aerobic bacteria. These Aerobic bacteria are what eat up all of the waste in the tank. They are much larger and more efficient at processing waste as compared to the anaerobic bacteria found in a conventional septic system.

Secondly, the air pump creates an action in the tank that breaks down large solids into tiny particles, making it very easy for the bacteria to attach to and devour the waste.

If you air pump quits working on your aerobic system, over a period of about 2 weeks the system will begin to turn back anaerobic. The biggest problem with this happening is that there is no secondary treatment system behind your aerobic system, as you have in a conventional anaerobic septic system. Once the aerobic system turns back anaerobic, instead of producing a clear odorless discharge the effluent will be closer to raw sewage. As you may realize, raw sewage discharging into a ditch, lake, or pond, or being sprayed on your lawn is not a good thing. This is why it is important to your system for the air pump to be up and running.


The other misconception is that the air pump just puts air in the water, so it doesn’t really matter which size is used. Nothing could be further from the truth. Air pump sizing is actually very important to the operation of your system, and not every system will use the same size air pump. If you have been our website, then you already know there are many different types and sizes. The air pump size is normally determined by the volume capacity of the tank, the style of air diffusers in the tank, and how many GPD (Gallons Per Day) the system is designed to treat.

Our sales team can make sure you get the right size pump if you are unsure about this aspect of buying a new one. In most cases we only need either the model number of the pump you are replacing, or the brand of your aerobic system and the GPD that it is rated to treat. Again, size does matter and it is very important that you get the correct air pump for your system.
