Pump

Pump if the second major component of the Swiftech H₂0-220 Apex Ultra+ liquid-cooling system. It is a powerful Swiftech MCP655-B (Laing D5) pump:

In fact, it is the best pump Swiftech currently offers. It is powered by a regular 12V molex-connector and consumes maximum 24W.

The internal diameter of the incoming and outgoing tubing measures 10mm. Overall, it is pretty compact (90 x 90 x 88 mm):

The sticker on the pump rotor is not very informative:

However, the official web-site states that its maximum performance is 1200 l/h with 3.1m maximum head. In fact, it is by far the best pump we have ever tested. I would also like to add that its claimed MTBF is 50,000 hours which is equivalent to 5 years of non-stop service. The liquid temperature, however, has to stay within 0-60°C range.
