I totally missed that the BK is on top in the drawing. So how does one sparge with only one pump? You would have to pump from HLT to MT and MT to BK at the same time.
You have your sparge water in the BK gravity draining. By the time it is all in the MT, you can briefly stop sparging and use the pump to pump about 2/3 of the runoff so far into the, now empty, BK. Your HLT is now empty, continue sparging the last 1/3 into it that is still in the MLT.
