More than one year later: I've now optimized the amount of blow-by on the Polaris cleaner entry port so that "just enough" unneeded flow occurs to convince the Intelliflow VF that priming was successful. With this optimization, the "wasted" flow causes only around 300W of extra power, instead...

@ride525 I basically have two solutions: 1. Open the "blow-by" valve on the Polaris 280 entry port until enough extra flow allows the pump algorithm to declare itself primed. This is the current solution, but the extra "blow-by" water under fairly high pressure waste 400-500 Watts while the...

Intelliflow VF Maximum Priming Flow to 15 GPM without contro SteveH: I have a very simple functional requirement compared to the amazingly versatile system you have developed. I would like to use the manual keyboard on the Intelliflow VF to adjust the Maximum Priming Flow to a low value, e.g...

mas985 - Thanks for the suggestion, but I already tried the hypothesis of assisting the booster by manually forcing the main pump run at maximum flow (3450 RPM) - it did not work. In filter mode, the main pump runs at 40 GPM, 2325 RPM and 800 Watt. This drops ~110W with the booster...

My booster pump VF numbers are: 15 GPM, 2380 RPM, 650 Watt This is in manual mode, with "constant flow rate" of 15 GPM selected. The Polaris 280 safety valve is opened for significant blow-by so the pump can achieve 30 GPM flow at start up. As pointed out previously, the 30 GPM flow is...

mas958, The main pump draws slightly less power (around 110w less) when the booster is on. That is a lot less energy than what the booster pump is wasting. I've confirmed by (manual mode) experiment that the key reason for this is the extra 15-20 GPM of flow needed to ensure "priming" of the...

Intelliflow VF - Getting Maximum Prime Flow Under 30 GPM Thanks for the great responses everyone. You correcctly state that I really don't have a priming problem. The VF is working just fine as a Polaris 280 booster at the moment. My quest (stated in the title) is to lower the energy usage of...

This is my first post on this forum - so please go easy :-D I have a 20,000 gallon pool with an Intelliflow VF as the main pump, driving a diatomacious earth (DE) filter. The setup has been working great for over two years. The pool sweep is a Polaris 280, with a separate 2hp booster pump...
