Even if you had 50 RD-30's in series the 350 is STILL going to have much less flow rate than the GTZ.
Except that the GTZ may top out, performance wise, at flow rate of x while the 350 may continue to improve through x so that it actually yields better results. And if x is below the rate of which a given pump is capable of flowing liquid through the 350... there ya go.
