Above: TPH 050

TPH series pumps are ISO and/or KF inlet flanges. TPU series have conflat inlet flanges. I believe all have KF outlet flanges. I thought the second number is supposed to indicate L/S but my TPH 050 plate clearly lists 25 L/s.

Smaller pumps (say < 50 L/s) tend to be passively cooled. Somewhat larger pumps can be air cooled but really large ones I think are only water cooled.
