is this what I need to have 2 D5's in series for improved flow rates?

[newls1]

going to be adding a water chiller into my loop and lm thinking having 2 D5's in series will greatly help my flow rates plus will more then likely be needed for the added length of loop and water tubings going out of case down to floor where chiller will be then back up into case. Prob will need all the head pressure I can get. Is this what im looking for? https://www.performance-pcs.com/wat...al-d5-serial-ek-xtop-revo-dual-d5-serial.html
