HIBLOW Works with Local Non-Profit


Did you know that HIBLOW works with non-profits?

We received a call from The Personal Integration Rehabilitation Program that has a large organic farm with a pond. They were looking for a donation of a couple of pumps to help clean up the pond and provide aeration for fish.

“The Personality Integration Rehabilitation Program endeavors to rehabilitate troubled at-risk young people through counseling, training in agriculture and animal husbandry, spiritual encouragement, and self-mastery through service to others. Participants receive basic education and job training as needed for the completion of a high school equivalency certificate, as well as valuable skills to enter and compete in the job market.”

We were able to rebuild and send them an HP-60 and an HP-80, and we have been told that the aerators have already cleared up 90% of the algae!

Whenever possible, we love to provide refurbished pumps to charities. If you think we might be able to help you, please give us a call or send us an email.

We have manufactured linear air pumps for the pond and aquatic industries for over 30 years. We know that reliability, energy efficiency, and low sound levels are all extremely important for your aquatic systems. Our pumps provide aeration and water circulation for water gardens, koi ponds, backyard/ farm ponds, aquaculture, hydroponics, and aquaponics.

Why Installing a Full Rebuild Kit is Critical to Pump Performance and Longevity


There are only a few moving components in a HIBLOW linear air pump.  Connected to the oscillating magnetic rod, the diaphragms wear and eventually rupture.  The umbrella valves that are located within the casing blocks open/ close 60 times per second and wear over time.  If the valves wear too much, the pump is not able to pressurize the air and your system’s performance will suffer.  The degradation of the valves is gradual, so the loss in pressure may not be noticed for quite some time.  It is prudent to replace the casing blocks and the diaphragms at the same time.

HIBLOW also offers a couple other rebuild kit options that include gaskets.  The black base gasket seals the upper and lower housing.  With years of use or in hot climates, the gasket can become brittle, and air can seep through causing a loss in pressure.  The filter cover gasket can also wear.  HIBLOW recommends checking the gaskets before rebuilding the pump.

Rebuilding a HIBLOW Pump: Should I Only Replace the Diaphragms?


It is inevitable that at some point in time your HIBLOW linear air pump will stop running. Most often that means that the diaphragms have ruptured, which activates the safety mechanism cutting power to the pump. This ensures that the magnetic rod does not tear up the inside of the pump – making it irreparable.

One of the advantages of choosing HIBLOW is that the pump can be rebuilt 2 times at a fraction of the cost of a brand-new pump. You may notice that there are different rebuild kit options on the market, most notably buying a full rebuild kit or the diaphragms only kit. It is HIBLOW’s strong recommendation to buy the full rebuild kit.

Steps to Calculate Friction Loss in Your Pond Aeration System


Example 1
: We have a ½ acre circular pond at 8’ depth.  The pump will be 100’ from the diffuser.  We looked at the HIBLOW pump sizing chart and determined that the HP-80 with 1 medium bubble diffuser is the best solution.    

  • Step 1: Add the water pressure and the diffuser pressure together.  8’ deep/ 2.31 = 3.46 PSI.  Our medium bubble diffuser adds 0.25 PSI. Total: 3.71 PSI
  • Step 2:  Determine the airflow of the HP-80 at 3.71 PSI. First, click on the HP-80 in the HIBLOW Model column on our website. Under product details, click “download specifications”. Looking at the HP-80 graph (pictured below): the air flow is right around 2 CFM or 57 LPM at 3.71 PSI.  The red line shows how the graph is interpreted. 
  •  Step 3:  Reference the HIBLOW USA Friction Loss Chart (link here).  The chart specifies PSI per 100’ of tubing.  The friction loss at 2 CFM or 57 LPM is about .45 PSI for 3/8” diameter tubing or 0.14 PSI for ½” tubing. In this case we would probably suggest going with the ½” tubing to reduce the pressure and increase the airflow.


*The chart is for schedule 40 PVC tubing.  Use the nominal diameter sizes for PVC.  Reference in the inside diameter numbers for weighted tubing.

**If you were running the tubing 200’ for example, you would need to multiply the PSI by 2 to get the total friction loss.  Friction loss at 200’ would be 0.9 PSI if using 3/8” diameter tubing and 0.28 PSI if using ½”.

  • Step 4: Calculate the Total System Pressure:  Water pressure + diffuser pressure + friction loss.  

For this example, our total system pressure using ½ diameter tubing is 3.85 PSI (3.46 PSI+ 0.25 PSI+ 0.14 PSI).  Looking back at the HIBLOW flow chart/ pressure chart (above), the total airflow entering the pond will be around 50-55 LPM or 2 CFM.  At this point it is important to make sure the airflow fits within the diffuser recommendation range.

How to Calculate Backpressure for a Pond Aeration System


Calculating or measuring the backpressure is important when planning and maintaining an aeration system. 

 Backpressure and air flow have an inverse relationship – the higher the pressure, the less the air flow. In reverse, the lower the pressure, the higher the air flow. The amount of airflow entering the pond is important to understand when choosing a pump, diffuser, and tubing. To estimate the amount of air flow we need to first calculate the total system pressure. 

Calculating System Backpressure:

  1. Calculate water depth backpressure:  Every 2.31 ft. of water depth is = 1 PSI.  Example: the water pressure for an 8’ deep pond is: 8’/2.31 = 3.46 PSI
  2. Identify diffuser backpressure:  A popular suggestion on the internet is a fine bubble stone diffuser, which can add as much as 1.5 PSI to the system and can easily plug.  HIBLOW recommends a medium bubble diffuser which typically puts less than 0.25 PSI on the system.  Regardless of which diffuser size/ type you choose, it is important to be able to estimate the amount of pressure the diffuser adds to your system.  Also note the amount of air flow recommended for the diffuser.  If below the minimum flow recommended, the air may not be strong enough to open the pores and “self-clean”.  This information will be important at the end of this exercise. For more in-depth information on diffusers, check out our article: https://www.hiblow-usa.com/2021/05/03/pond-aeration-system-diffuser-options/
  3. Calculate friction loss: Air flowing through the tubing will create friction loss (added pressure).  The air pump size, length of the tubing, number of lines, elbows, and diameter of the tubing will all factor into the calculation.


First, we need to figure out the diameter of tubing that is best for your set-up.  As a rule of thumb, for any run within 50’ a 3/8” tube is likely ok.  From 50’-100’ we typically suggest ½” diameter tubing.  Anything beyond 100’ we suggest ¾’ diameter tubing.  However, that is just a rule of thumb and there are exceptions based on the amount of air flow from the pump (pump size) and the back pressure.

How to Spot Fake HIBLOW Repair Kits on Amazon


For nearly 3 years, a Chinese company has been manufacturing knock off repair kits for HP Series HIBLOW pumps. They look nearly identical at first glance, and their sellers on Amazon and eBay often include language in the listing that is meant to deceive. Don’t be fooled!

Installing a knock-off repair kit can be disastrous. Often the parts will not fit properly which can cause the rod to move out of alignment and destroy the inside of the pump. The pump can also run louder. The diaphragms often rupture in a few months, or even a few days.

How do you know if the parts are a knock-off and not authentic?

Find out on our website! 

Help us out!

If you buy a knock-off kit, please leave a negative review, and report it to Amazon or eBay. As is the case with other knock-off products around the world, “reviewers” are hired to increase the ratings to deceive the end user.

Beware of Knock-Off HIBLOW Pumps on eBay!

Have you seen HIBLOW repair kits on Amazon or Ebay recently?

Are you sure they're genuine? 

For over a year, we've been getting reports of counterfeit repair kits being sold on the internet. Some of our customers have been fooled, and we want to make sure you don't waste your money!

Unauthorized repair parts in a HIBLOW pump will void your warranty, and will ultimately cause you more issues with your pump than you started with.

Read more about how to spot fakes on our website, and how you can help us get these counterfeit products off the market!
