Same reply as in another thread: As for the Leimbach system, it seems there's little difference in strength when it comes to the pump's speed. Here's a little test I did yesterday: http://www.youtube.com/watch?v=aqNTPp1g4pE

If you look at performance graphs for gear pumps the faster they rotate the greater volume they move which overcomes the internal leakage more and more.
However like most things there is a compromise and they will consume more and more power as they do this.
