What is a hydraulic power pack and how does it work?
A hydraulic power pack is a self-contained unit that supplies power to a hydraulic system, enabling controlled movement and force application. It consists of:
- Prime mover (pump drive) – Converts mechanical energy into hydraulic power.
- Hydraulic pump – Generates flow and pressure to drive system components.
- Reservoir – Stores hydraulic fluid, ensuring consistent operation.
- Hydraulic controls – Regulate pressure, flow, and direction for precise system performance.
Hydraulic power packs are designed to perform multiple operations with varying forces and speeds, powering hydraulic motors, cylinders, and actuators in both rotary and linear applications.
Several factors influence a hydraulic power unit’s performance, including pressure limits, power capacity, reservoir volume, and physical characteristics such as size, power supply, and pump efficiency.
Here are some of the most common questions we receive about hydraulic power packs and system design…

Read more hereWhat factors should be considered when specifying a hydraulic power pack?
Several key factors influence hydraulic power pack design, including:
- Operating environment – indoor, outdoor, or hazardous locations requiring ATEX/UKEX compliance.
- Application requirements – load demands, system integration, and hydraulic system design considerations.
- Prime mover type – electric, petrol, or diesel-driven options based on power needs.
- Forces and speeds – ensuring the unit meets flow rate and pressure requirements.
- Duty cycle – continuous or intermittent operation affecting cooling and efficiency.
We can guide you through these factors to ensure the best solution for your needs.
Get in touchHow is hydraulic power pack performance and capacity calculated?
Several factors determine a hydraulic power pack’s performance, including:
- Pressure and flow rate – higher pressure increases force, while flow rate affects speed.
- Power capacity – available energy from the motor or engine impacts efficiency.
- Reservoir volume –
- ensures adequate fluid supply for continuous operation.
- Pump characteristics – flow rate and pressure must align with system requirements.
Understanding these elements helps optimise hydraulic system design for efficiency and reliability. Learn about this and more over in our Fluid Power Technical Knowledge Hub.
Learn moreDo you offer hydraulic power pack repairs?
Yes, we provide comprehensive hydraulic repair services for power packs, pumps, motors, cylinders, and other hydraulic components. In many cases, a well-repaired unit performs like new, restoring efficiency within your hydraulic system design.
