EHL Hydraulic Power Units: Custom Designed, Manufactured and Supported for Any Application
Hydraulic systems remain the driving force behind some of the world’s most demanding industrial, mining, marine, energy, manufacturing, and infrastructure applications. At the heart of these systems lies the Hydraulic Power Unit (HPU), the critical component responsible for generating, controlling, and delivering hydraulic power precisely where it is needed.
At EHL, we understand that no two hydraulic applications are identical. Operating conditions, performance requirements, environmental factors, duty cycles, available space, and client objectives all influence the design of a reliable hydraulic power solution. That’s why EHL specialises in the design, manufacture, commissioning, and ongoing support of Hydraulic Power Units of virtually any size or capacity, providing tailored solutions that deliver efficiency, reliability, and long-term value.
Whether you require a compact HPU for a specialised machine, a high-capacity power unit for heavy industrial processes, or a fully redundant critical-duty hydraulic system, EHL has the engineering expertise and manufacturing capability to deliver.
Why Hydraulic Power Unit Design Matters
A Hydraulic Power Unit is far more than a reservoir, pump, and motor assembly. It is the central nervous system of a hydraulic operation, influencing:
- System performance
- Energy efficiency
- Equipment reliability
- Component lifespan
- Safety compliance
- Maintenance requirements
- Operational costs
Poorly designed HPUs can lead to excessive heat generation, contamination issues, inefficient energy usage, component failures, and costly unplanned downtime.
EHL takes a holistic engineering approach, ensuring every HPU is designed specifically around the operational objectives of the client while meeting all relevant industry standards and performance requirements.

Customisation Built Around Your Application
Every hydraulic application presents unique challenges. EHL’s design philosophy centres on customisation rather than forcing clients into standardised solutions.
Our engineers consider:
Flow and Pressure Requirements
Accurate hydraulic calculations ensure the HPU delivers the exact flow rates and operating pressures required by the system, maximising performance without unnecessary energy consumption.
Environmental Conditions
EHL designs systems for operation in:
- Extreme temperatures
- Dusty environments
- Offshore locations
- Corrosive marine conditions
- Remote installations
- Hazardous areas
Space Constraints
Where installation footprints are limited, EHL develops compact and efficient layouts without sacrificing maintainability or performance.
Duty Cycles
Whether the application requires intermittent operation or 24/7 continuous service, every system is engineered for the expected workload.
Future Expansion
We regularly incorporate scalability into our designs, allowing clients to expand system capability as operational demands evolve.
