Voltage is No issue Cather, even with current MAG, as it will reduce duty cycle and transistor / coil loading, not increased it.
In a fixed flow system, this effect is common.
What will to flow be for new pump?
Need to guess at 180-200 gph, as it was no designed by myself, and we where only given a targeted head.
It is odd you and this company have same spec's, as I can just about be 100% sure they have nothing to do with PC liquid cooling. It is a very large world wide company, and I guess it is possible there is some co-developement somewhere.
I would suggest one of there engineers is likely reading this board
