The pressure compensated pump adds heat when it is the compensated more.
If your case drain is generating 1gpm and your compensator is set at 2000psi the heat generated is (1gpm x 2000psi) / 1714 = 1.167 Hp. 1.167 hp x 2544.43 = 2969.35 btu
That is how much heat the pump is generating when it is compensated.
Then observe the case flow of the pump during operation under load and perform the same calculations and use the same calculations as above.
Then observer a pressure gauge at the pump outlet and a pressure gauge at he actuator work port. Subtract the work port pressure from the pump outlet pressure and this will tell you system pressure drop. This is psi not used for work and is turned to heat. Use same above calculation with this pressure and pump flow and this will give you the additional system heat generation.
After you adjust all of this for time compensated and non-compensated you still have to calculate the heat your system is able to dissipate.
You need to take into account the ambient temp of the hydraulic reservoir location.
Be aware that your electric motor has a no load amperage rating. This is what the motor amp draw is with zero load.
