You don't want to get an Iwaki "X", that's the high flow type. Look for a "Z".

To basically quote pauldenton from a PcPer post a while back when he helped me select my pump...

Iwaki Model Numers:
- MD rather than WMD indicates the more desireable Japanese motor.
- "L" in an iwaki indicates it's 115V (rather than 220V )
- "T" indicates threaded fittings - no "T" (as in this case) indicates barbs, in the case of an MD-20R 18mm OD inlet and 17mm OD outlet.
- "X" would indicate a low head/high flow model - to be avoided for water cooling
- "Z" would indicate the high head models (best for most setups but rarer and more expensive)
