Hydraulic power packs (HPUs) are the energy generation, storage, and control centers of hydraulic systems. By combining pump, motor, tank, valves, and auxiliary equipment into a single unit, they:
Provide stable pressure and flow
Define system efficiency
Directly affect equipment lifespan
Manage heat and oil cleanliness
Incorrectly designed or improperly selected power packs can cause overheating, energy loss, pump failure, and unplanned downtime.
Parker Hannifin offers globally engineered, long-life, and high-performance hydraulic power pack solutions, recognized as a reference brand in the industry.

Pressure & Flow: Pump capacity must match system requirements
Tank Volume: Critical for oil temperature, air separation, and cavitation risk
Cooling: Mandatory for continuously operating systems
Motor Type: Electric (IE3–IE4) or diesel depending on application
Energy Efficiency: Variable displacement (V-PAK) solutions provide significant energy savings
Filtration Level: ISO 4406 cleanliness class must be defined
Insufficient tank volume → oil overheating
Incorrect motor power → poor performance or excessive energy consumption
Inappropriate oil viscosity → reduced pump and valve lifespan
Neglected cooling → reduced system efficiency
Misaligned installation → internal leakage and early failure
