Variable Speed Pump VS 3050---gpm/rpm?

[oroepke1]

Thanks, I had seen that graph but what is my TDH? I don't want to go through all the formulas.....

I have a DE 100 filter and also a Ozonator and they told me for the ozonator to work right, I need the high flow, does that make sense?

Do you have automation, such as an Easytouch system? THat makes flow rates much simpler as there is a spreadsheet that relates RPM and Wattage to determine flow rates.

TDH is Total Dynamic Head, usually expressed in feet (of water). Dynamic head is the resistance (pressure) associated with water flowing in pipes and through inlets/outlets. Static Head is pressure associated with an elevation difference though usually this is canceled out between the suction and pressure sides of the pump. Static head is more relevant for whether you can prime the pump or to raise water to a solar panel on a high roof.

Yes I have an Easytouch System, but haven't played much with it since I spent all of my available time in the water I guess I will dig into the manual sometime soon .....And thanks for the explanation of static and dynamic head!

I am sure I will be back with questions soon, this is a GREAT forum, thanks!

There are a couple of ways to get to GPM for the Intelliflo. If you know the wattage that the pump is drawing, the link labeled "Pump Modeling Tools" in my signature, there is a spreadsheet which relates GPM, RPM and watts.

If you don't have a power reading then I can make guess for you based on some additional information.

Pipe size and number of runs pool to pad for both suction and return.

Filter PSI at a given RPM, preferably at a higher RPM.
