It would seem to me that the higher rate of flow wouldn't allow the water too cool off as efficiently as a slower rate of flow. Are there any other possible issues with using this higher rate pump such as pitting internally from cavitation?
What modifications (to the pump, wiring, outlet, inlet, etc.) have to be made in order to use this pump?
Thanks
