I’m just trying to expand my knowledge. Being in the pool industry for years, I’ve learned a lot, but also learned what I haven’t learned ?. What is the point in the stealth pump? I understand the size differences for the ports and the basket, but is it just a marketing thing or is the stealth hydraulically better ie. better with less back pressure or with larger plumbing etc. Just curious.

Welcome to TFP.. Because you are in the pool "industry" you will soon see an "In the Industry" tag below your name.
I'll send you a PM.
Thanks,
Jim R.

ka,
For the members like me, who have nothing in their "head", can you tell us what that means to the average pool owner/user?
Thanks,

For any pump, you want to look at the pump curve, which shows how the flow varies with pressure (head).
Low head pumps work best with low pressure applications, like a fountain.
Medium head pumps work in general use applications.
High head pumps work best with higher pressure applications, like pumping the water up to a two story roof for solar.
When choosing a pump, the desired flow is used to calculate how much resistance (pressure, head or head loss) will be generated by the system at that flow rate.
The point on the pump curve where the pressure and flow intersect is called the operating point.
The operating point should be near the middle of the pump curve.
Pumps do not perform well near the ends of their curves.
For example, if a WhisperFlo pump (high head) is used on a fountain (low head application), the pump will run too far to the right on its curve, which can cause multiple problems like noise, maybe cavitation and it's very inefficient.
A properly chosen pump, like a fountain pump, will be quieter and more efficient.
When choosing a pump, you should look at the maximum head (given in feet) and the maximum flow as shown by the curve. Then choose a pump that will operate within the limits but not near the limits.
A properly designed system should generally not need high flow or create high head.
High head can be created by rooftop solar or in-floor cleaner systems.
The maximum flow usually needed for a residential pool will usually be due to a big gas heater (400,000 btu/hr) that might require about 40 to 50 gpm.
Other than that, the flow can usually be pretty low (about 20 gpm).
A two speed or variable speed pump that runs on low except during times where higher flow or pressure is required can be a good choice.
Any new pool should use a variable speed pump.
If a single speed pump is used, it should be a maximum of 1.0 total hp.

Fantastic info everyone! I’m getting more into the sciences of pools now instead of just knowing how to do things, so thanks for a great first thread for me!
