high head and medium head pool pump

Which is Best: High Head or Medium Head Pumps?

After my last article on how to calculate the total dynamic head (TDH) of your swimming pool, I decided to tackle a subject in a similar realm: high and medium head pumps. In the Total Dynamic Head (TDH) blog post we explained that TDH is essentially the force/resistance working against the pump as it pushes water through your pipes. The higher the feet of head, the harder your pump needs to push to counteract that resistance.

Calculate your feet of head according to the blog post or your choice of online calculator and select the style of pump accordingly:

  • Medium Head Pump < 65 Feet of Head
  • High Head Pump > 65 Feet of Head

How to calculate head for pool pump?

How Do I Calculate Feet of Head for My Pool?

OK, riddle me this, you’re standing in a pool store’s showroom and you’re in awe of all the shiny new pumps. You finally make your decision on the model you want and have a hunch it will work well in your 20 000-gallon pool, but the salesperson drops a bomb on your plans by asking the simple question, “What is your feet of head?” Wait a minute, what? My head is about 10 inches. but I’ve never actually measured my own skull…

Wrong head.

Total Dynamic Head (TDH) refers to the total equivalent height that a fluid will be pumped by taking into consideration any friction losses in the pipe. Essentially “dynamic head” is the measurement of resistance working against your pool pump as it pulls water from your basin and pushes it back to the pool. The total sum of the pipes’ lengths, rise in elevation and addition of 45-degree /90-degree turns will affect the feet of head number. All the aforementioned plumbing quirks add up to more friction the water accrues as it travels. The more friction, the harder the pump must work to push the water through the pipe, which demands that you go to a higher HP or use a larger pipe.If you need to install a new pump or replace your filter, you need to calculate the system’s feet of head to determine the best fit. A pump’s flow rate is dependent on the feet of head.

Pool Pump or Pool Motor?

Pool Parts 101: The Difference between a Pump and a Motor

Here’s the difference between a pool pump and motor

Ok, hear me out. This topic may be on the little shallow end in terms of depth of discussion but for new pool owners this subject can be confusing. I have worked at Inyo for years and if I had a nickel for every time a caller described a motor as a pump or a pump as a motor I would have $20,483.15 (probably not an accurate count.) But you get my meaning. It happens a great deal and the miscommunication can cause frustration for both the customer and the technician, so I am here to clear it up. (more…)
