Hydraulic Power Unit Lifecycle Services

Hydraulic power units (HPUs) are often kept in service far longer than their original design life. Repair and refurbishment procedures provide a controlled way to extend asset life while maintaining system performance and compliance.

We deliver complete end-to-end hydraulic power unit repair and refurbishment services, managing the process from fault identification through to verified return-to-service readiness.

HPU Inspection, Diagnosis & Repair Scope

Each power unit is evaluated as an integrated system, with operating checks used to detect internal damage, instability, and configuration issues before corrective work is carried out.

Our scope of service covers:

• Full inspection and condition assessment of hydraulic power units
• Fault diagnosis of pressure, flow, heat, noise, and control issues
• Pump and motor repair, rebuild, or replacement
• Valve bank inspection, reconditioning, and calibration
• Reservoir inspection, cleaning, and contamination control
• Hose, fitting, filtration, and auxiliary component replacement
• Electrical and control component inspection, where applicable

Repair decisions are based on the unit’s operating requirements, condition, and service expectations rather than a one-size-fits-all approach.

Refurbishment & Enhancement Options

Where appropriate, system renewal and enhancement offer the opportunity to improve reliability, efficiency, and service life, not just restore function.

Configuration upgrade options may include:

• Component reconditioning to OEM performance tolerances
• Upgrading pumps, motors, or valves to suit revised duty requirements
• Improved filtration and contamination control
• Heat management improvements and cooling upgrades
• Layout or mounting modifications for serviceability and safety
• Compatibility support for mixed or legacy hydraulic systems

Application-Specific Custom-Built Hydraulic Power Units

In addition to repairs and refurbishments, we also design and build custom hydraulic power units for specialised applications. This includes standalone and integrated HPUs engineered to suit specific duty cycles, operating environments, and compliance requirements.

Learn more about our custom hydraulic power unit design and build capabilities here, or view our previously engineered HPU case studies, including solutions developed for a mining haul truck recovery application and an industrial tensile testing system

Verification & Testing

Before returning to service, each hydraulic power unit undergoes structured verification to confirm correct operation and system stability.

Verification processes may include:

• Pressure, flow, and functional testing to confirm performance against design parameters
• Verification of OEM-aligned tolerances and settings for predictable system behaviour
• Cleanliness and contamination control checks to protect rebuilt components
• Confirmation of component suitability for duty cycle, load, and operating environment
• Post-repair assessment to identify potential contributors to repeat failure or early wear
