Hi all,

I'm looking for a CO2 circulation pump, max flow 10 Lt/h or ~2.5GPH. Any ideas?

Thanks in advance, cheers :)

Try HERMETIC PUMPS, the CAM type for R744 (even so I think CAM gives more flow for a little H.

Believe me I've been searching the web and still didn't found the stuff I really need.

As I said I'm looking for a low flow Pump to use in a small HFC-CO2 as secondary fluid system. I'm using a secondary system because I really want to keep oil out and low flow because I'm doing 2-phase CO2 HTC and DP measurements in minichannels.

I have a R404a-R744 3kW system running with a LEWA membrane pump for big evaporator testing but now I'm looking for a centrifugal pump for smaller business.

Anyway, thank you guys for all the info I already found very interesting stuff :D

Cheers!

Waht are the pressure losses you have in your mini channels?

Is it not possible to manage your system with thermosiphon?
