POWER PACK PROBLEMS
When the power pack fails, the machine stops.
A hydraulic power pack may be only one part of a larger machine, but when it develops a fault, the consequences can affect the whole system.
Loss of pressure, poor flow, leaks, overheating, pump problems, valve faults or electrical issues can all affect performance. The right answer is not always to replace the complete unit.
You do not need to diagnose the fault first.Tell us what the machine is doing, send photographs or drawings, or bring the power pack to our Keighley workshop and we can help establish the practical next step.

WHAT WE CAN HELP WITH
Repair it. Refurbish it. Modify it. Or build a new one.
We assess the requirement and choose the practical engineering route rather than assuming a one-size-fits-all solution.
Repair & refurbishment
Where practical, repair or refurbish the existing unit rather than replacing everything unnecessarily.
Upgrades & modifications
Modify an existing power pack where the machine or operating requirement has changed.
Bespoke power packs
Develop a new power-pack solution around the application, space, hydraulic duty and control requirements.
OUR APPROACH
Don't replace the whole system until you've found the real problem.
Correct diagnosis helps establish whether the practical route is component repair, refurbishment, modification, replacement or a new design.
Start with the machine
We establish what the power pack does, what the machine needs and what has changed or gone wrong.
Inspect the unit
We look at the power pack, components, connections and available information before recommending a route.
Repair, modify or build
The solution may involve components, hydraulic circuit changes, refurbishment or a replacement power unit.
Check & hand back
Where applicable, completed work is checked before collection or return to the machine.
WHAT'S INSIDE A POWER PACK?
Every component has a job to do.
A hydraulic power pack, or hydraulic power unit, combines the components needed to generate and control hydraulic power. The exact specification depends on the application.
Hydraulic pump
Converts mechanical drive into hydraulic flow for the system.
Electric motor
Provides the mechanical drive required by the pump and application.
Reservoir
Stores hydraulic fluid and provides the volume required by the system.
Valves & manifold
Controls pressure, direction and flow according to the hydraulic circuit.
Filtration
Helps manage contamination and protect hydraulic components.
Controls & instrumentation
Pressure switches, gauges, sensors and electrical controls can form part of the unit.
ENGINEERED AROUND THE APPLICATION
The right power pack starts with the machine.
There is no single power-pack specification that suits every application. The hydraulic requirements need to be considered alongside the machine, available space and operating conditions.
- Required flow and working pressure
- Duty cycle and operating conditions
- Pump, motor and drive requirements
- Reservoir capacity and heat management
- Valves, manifold and hydraulic connections
- Electrical controls and instrumentation
WHY THE DETAILS MATTER
A power pack is part of a hydraulic system.
Changing one component can affect the rest of the circuit. We therefore look at the power unit in the context of the machine and its hydraulic requirements rather than treating it as an isolated box.
Hydraulic power-pack work at our Keighley workshop
WORKSHOP ENGINEERING
Built by hydraulic engineers.
Power packs sit at the centre of many hydraulic systems, so getting the details right matters.
Our workshop approach combines practical hydraulic engineering with the ability to inspect, repair, modify and manufacture around the requirements of the machine.

EXISTING POWER PACKS
Repair the power pack you already have.
If an existing power pack has developed a fault, replacement may not be the only option.
Depending on what we find, the practical route may involve replacing failed components, addressing leaks, investigating pressure or flow problems, modifying the circuit or refurbishing parts of the unit.
Where the existing power pack is no longer suitable for the machine, we can discuss replacement or a more appropriate engineered solution.
01Component repair
Where the unit remains suitable and the fault is repairable.
02Refurbishment
Restore a serviceable unit where several components need attention.
03Modification
Adapt an existing unit where the machine requirement has changed.
04Replacement
Specify a new unit where the existing one is obsolete or unsuitable.
BESPOKE POWER PACKS
Need something different? We can build around the application.
Standard power packs can work well when the application fits the specification. Some machines need something more specific.
Available space, hydraulic duty, controls, mounting requirements and existing connections can all influence the design. A bespoke power pack lets the solution be developed around those requirements.

WHAT TO SEND US
Useful information for a faster assessment.
- Photos of the complete power pack
- Photos of the pump, motor, valves and connections
- Existing model or part numbers
- Hydraulic circuit diagram, if available
- Machine/application details

HYDRAULIC POWER PACK FAQ
Common questions about hydraulic power packs.
What is a hydraulic power pack?
A hydraulic power pack, also called a hydraulic power unit, is the part of a hydraulic system that generates and controls hydraulic power. Depending on the application it can incorporate a pump, drive motor, reservoir, valves, filtration, controls and associated components.
Can you repair an existing hydraulic power pack?
Yes, where the unit and application are suitable for repair. We can assess the power pack and help determine whether repair, refurbishment, modification or replacement is the practical route.
Can you build a bespoke hydraulic power pack?
Yes. Where a bespoke solution is appropriate, the power pack can be developed around the application's flow, pressure, duty cycle, available space and control requirements.
What information do you need to specify a power pack?
Useful information includes the machine or application, required flow and pressure if known, duty cycle, available space, motor supply, existing hydraulic components and any drawings or circuit diagrams.
Can you work from an existing power pack?
Yes. An existing unit can provide useful information about the required components and configuration. Photographs, model numbers, component markings and circuit diagrams can also help.
Can an obsolete hydraulic power pack be replaced?
Where the original unit is obsolete, a replacement may be specified around the machine's actual hydraulic requirements, available space, control requirements and existing connections.
How do I get a hydraulic power pack quote?
Contact Active Hydraulics with details of the machine or application and provide photographs, drawings or information from the existing power pack where available.
