EX2-755 Pump

Postby Fizzy » Tue Jan 24, 2012 12:10 am

There is not much on the pump that this system uses. The only info is '7L/min (1.85 gal/min), 2.6m (8.5ft) head pump'. And the replacment product page ( http://www.koolance.com/water-cooling/p ... ct_id=1073 ), has no spes at all.
So whats the differance between this pump and the older Exos 2's with the PMP-400 pumps? Is it a better pump?

The link you provided has a PMP-300, compare it to the replacement parts of the RP-980 for example which has a PMP-300. Same pump same housing.

The PMP-400 has a much higher head pressure than the PMP-300 however the PMP-300 draws half the power of a PMP-400.
PMP-300: 9.6W @ 12V, 6-12VDC, 7 L/min (1.85 GPM), 2.6m (8.53ft) head,
PMP-400: 20W, 8-13.2VDC, 8.7 L/min (2.3 GPM), 7m (23ft) head

Thnaks. So basiclly its just a dressed up PMP-300.
I have an Exos-2 LX now and its about 3-4 year old. But I dont like the Reservoir's inside design. I assume that the design is supposed to circulate the fluid inside it, but it seems that it always need to be topped off with coolent or else it the pump makes a crackling noise when it hits some foam or air bubbles. But I want to see if it is worth upgrading or not.
