Impossible pump requirements?
Impossible pump requirements?
(OP)
Is there a way to get 1500psi of hyraulic fluid at a flowrate of 2400 gpm into a cylinder without having 2000 hp pump. Someone suggested having an air over fluid reserve and pumping the air to force out the fluid. Also if anyone knows of pump manufacturer who can pump 2400 gpm of hydraulic fluid at 1500psi let me know. Thanks.

End of discussion.

Use a 2000 HP motor and not a 2000 hp pump.
HP=gpm x delta psi x .00058 = 2088 hp.
Note: this is not taking into consideration the motor/pump efficiency, it is the hydraulic hp.

Many hydro turbines use air over oil to drive the servomotors (big rams) that close the wicket gates. This decouples the instantaneous servomotor power requirement from the pump rating. The main reason in this application is to ensure the wicket gates can still be closed if the pump or its power supply fail. However the principle is still the same.
If your duty is continuous then obviously the pump hydraulic power must exceed the cylinder demand.

Thread71-84432 there off the self hydraulic pumps capable of producing a load of 1000-2000hp and spin at 8000-10000 rpm or would they have to be geared slower?
