Flow Jet Pump

Which efficiency is better in cooling Water Flow Rate (One Way) around a Reciprocating Pump. Fast or Slow ?

In my Water Jet Granite Cutting M/c. the reciprocating water pump works at 70,000psi. There is a one way water cooling system around the pump. What flow rate is better, Fast or Slow ? to maintain the reciprocating pump.

1. Faster flow rate would dissipate heat at an increased rate
2. The slow rate will need less pumping power but the cooling water will heat up more. If the cooling water outlet temperature is still quite low using slow rate then it will be ok. If however the water outlet from the machine is getting very hot, better stick to the fast rate.
