More than enough.
At 9K this pump only requires 13 in-oz. of torque. Looks like the B23-G-75 produces ~23 in-oz. @ 10K
The only concern I have is the current draw. 15.A @ 12 V = 186W. that's just a tad much for a rheostat. The B23-I-75 has the same specs but only draws 6.2 A, but probably at 3X the cost.
