Recommendations re: a very high pressure low flow pump

[andy497]

I'll be receiving a thermotek laboratory recirculating chiller in a couple of days. I've got a pq curve for the built-in pump, and it's pretty interesting. This pump develops over 20 feet of head for one, and it still pumps ~0.4 gpm at 20 feet! However, the free flow is only rated at 1.0 gpm. With restriction equaling 5 feet of head, it is still rated for 0.9 gpm, so 0.9-1.0 gpm is probably what I'm going to see in my system.

Should I try to make this pump work? I've got swiftech blocks on the way. They might actually work pretty well. I wonder if I should try to accelerate the water at the blocks and make use of that crazy pressure.

Otherwise, the thermotek internals are 12V, so I could probably swap out the pump for a danger den.

p.s. this chiller is rated to cool a ~185 watt load to 10 C below ambient. And supposedly at 43 dB. I can't wait to try it out!

use that pump, wbs as is (the inlets are tapered, no easy way to bush down)
