The pumps are unique so I will try to post a link to them. The versions I use, "Strong" are two wire pumps. From my understanding the Vario, Solar and Basic all reach their maximum output at roughly 12vdc. The Strong model can increase output with the higher speed that comes with higher...
Thanks to you and the other posters. These pumps are electronically commutated so no brushes. I will contact the linked company to see if they offer another solution.
My problem: I need to lower maximum voltage in a nominal 24vdc circuit. The circuit drives a pair of pumps in parallel each rated at 8-24vdc and the pump set has a caveat not to run at over 24/25VDC (the caveat I believe is because of unbalancing the impellers at the speed 24+ will create.)...
