Question for Martinm

[jayhall0315]

Hello Martinm - Been away for awhile and have the Koolance RP-452X2 dual D5 reservoir and will be running one regular D5 Vario and one D5 Strong in series for one large CPU -GPU - Board loop. My question is what rpm do I run the D5 Strong at to match the regular D5 at setting 3 and setting 5 (so there is no cavitation noise in the res) ? I have the bleed kit, the U connector and the Koolance speed control unit for the D5 Strong.

Thanks - Jay

Also Martinm (or other gurus), what is the most up to date method for running this 452X2 with pumps in series without any bleeding problems, air bubbles or cavitation ?

But I haven't been keeping up with the forums myself...been busy with a new job and playing with ATV/buggy stuff again.

Take HER easy..:up:

Great, thanks Martin. Didnt see that article but should have known you would have examined the D5 Strong in detail, hehe :)
