Good comparative testing of the popular pump choices out there at the mo:

MAGII LE: (at 11.98V) ~3psig (6.92' -- 2.11m)

3psig ~= 83.03" water column at 4 deg. C (using the same conversion that Lee at SystemCooling does--1.0" = 0.03613psig)

CSP-MAG: (at 11.98V) ~2.8psig (6.46' -- 1.97m)

2.8psig ~= 77.5" water column at 4 deg. C

AqX 50Z-DC12: (at 11.93V) ~5.2psig (11.99' -- 3.66m)

5.2psig ~= 143.9" water column at 4 deg. C

Laing D5 (Swiftech MCP655): (at 11.89V) ~6psig (13.83' -- 4.22m)

6psig ~= 166" water column at 4 deg. C

Laing DDC+: (at 11.88V) ~8.5psig (19.6' -- 5.98m)

8.5psig ~= 235.26" water column at 4 deg. C
