Peak hydraulic systems demands may be met by the use of what ?

The answer is: Variable displacement pump.

Explanation:

The pump increases the hydraulic pressure to the nominal value required by the system.

Variable displacement pump: A variable displacement pump has a fluid outlet that varies to meet the system's pressure demands. The pump output is automatically changed to a compensating pump inside the pump.

Variable displacement pumps are independent of the number of revolutions per minute of the pump as the amount of liquid displaced depends on the needs of the system.

The answer is: Variable displacement pump.
