Pentair SuperFlo Bench Test (120V / 1.5" pipe)

Pentair SuperFlo Bench Test 120V / 1.5 inch pipes
This article is a continuation of a variable speed pool pump testing series where I am testing power consumption, flow rates and motor RPM for popular models of pool pumps. In addition to testing these pumps I am also testing under various pipe configurations and sizes to help compare and learn about how much pipe sizing, and pipe configuration, can affect the performance of your pump. To see another configuration of this pump you can also check out how this pump performs with a 240 volt electrical supply versus this article and video which is looking at a 120 volt electrical supply: Pentair Superflo VS 240 Volt bench test.


This bench test looks at the Pentair Superflo variable speed pump, #342001, that is installed with a 120 Volt power supply. The plumbing configuration for this test is simulating a very common configuration of two 1.5" suction lines and one 1.5" return line. It is important to understand that this is a bench test simulation and not an exact recreation of a pool and plumbing system. Further to this, each swimming pool and plumbing installation is completely unique and the flow rates and inherent resistance to flow will depend on a great deal of variables ranging from how many pipes you have, their size and how they are connected, all the way to what type of filter you have and how dirty it currently is. This bench test simplifies the complexity of the variables by removing many of them so that a direct comparison can be made between pumps, pipe sizes and pipe configurations.

It is important to understand that while the high rate flow meter used here is calibrated to be accurate to within 2% of actual flow, there is also the fact that I am reading and interpreting this analogue measurement...something that surely introduces a tolerance of error into the reading. Instead of the exact flow rates, you should be instead looking at the general trends of flow rates versus electrical consumption such that you can get a better picture of how flow rates change and power is consumed. Also worth noting is that the Wattage consumption for this bench test uses calculated values by multiplying current by voltage.


This this test I elected to use a very common Wattage meter as these were the most popular Wattage meter on Amazon by a long shot. If you have one of these at your home already this is probably the one you have, and if you go shopping for one tomorrow this is likely the model that you will end up with. 240 Volt Wattage meters are a lot less common and especially so for residential applications. The 240 volt Wattage meters that I also use for these bench tests is something you need to build into a control panel box yourself along with a DIN rail to mount it on. The Kill-A-Watt 120 Volt meter is ready to use out of the box as you see it in this video.


Be sure to subscribe to the Swimming Pool Steve YouTube Channel to see if changing the size of the suction and return pipes, or changing the number of pipes used, has a measurable result on the electrical consumption and flow rates.
