Compact Hydraulic Power Unit — available in DC/AC configurations for UK industrial applications
What Makes This Hydraulic Power Unit Different
The compact hydraulic power unit is built on a high-efficiency, low-noise, small-displacement gear pump whose selection range spans from 0.17 ml/r to 8 ml/r — giving engineers in the UK the flexibility to match pump output precisely to their system demand. The valve block is machined from high-strength aluminium alloy, cutting both weight and corrosion risk compared to cast-iron alternatives. Zero-leakage cartridge valves are fitted as standard across the range, so pressure retention between actuator cycles is reliable and measurable. Return oil passes through a throttle valve, producing a steady, controlled drop with minimal hydraulic shock — a characteristic that protects sensitive downstream equipment in automotive warranty bays, machine tool fixtures, and agricultural machinery just as effectively in a Sheffield workshop as in a rural farm operation. Whether the application demands electric control or manual operation, the unit accommodates both, and a manual emergency reversing valve is always available as a safety fallback.
Engineering Advantages at a Glance
Dual Motor Compatibility
Accepts both DC (2 V, 24 V, 36 V, 48 V) and AC (110 V, 220 V, 380 V) motors, so the same power unit body integrates into mobile battery-powered plant or mains-connected fixed machinery without redesign.
Aluminium Alloy Valve Block
The lightweight aluminium alloy manifold resists corrosion, reduces overall system mass, and is machined to accept universal standard jacks — simplifying field maintenance without specialist tooling for UK service teams.
Proportional Speed Control
An optional electromagnetic proportional reversing valve enables precise closed-loop speed control of the actuator — critical in precision lifting platforms, automated snow-plough rigs, and loader applications where velocity ramping is specified by the OEM.
Zero-Leakage Cartridge Valves
High-performance cartridge valves with zero measurable leakage ensure that load-holding pressure is maintained between work cycles. This directly reduces energy consumption and heat generation — two common concerns in continuous-duty mining and agricultural applications.
Low-Noise Operation (≤70 dB)
With noise output capped at 70 dB, this compact hydraulic power unit meets the occupational noise standards relevant to UK workplaces under the Control of Noise at Work Regulations 2005, making it suitable for enclosed workshops, automotive dealership service bays, and indoor logistics centres.
200+ Circuit Configurations
By combining the available hydraulic valve options, engineers can select from more than 200 distinct hydraulic circuits. This breadth means the same platform can be specified for single-acting or double-acting cylinder control, sequence circuits, pressure-reducing circuits, and regenerative flow configurations.

Where This Compact Hydraulic Power Unit Works
Across the UK’s manufacturing, agriculture, logistics, and mining sectors, the compact hydraulic power unit has been deployed in an enormous variety of configurations. The combination of a small overall footprint, high working pressure, and adaptable motor selection means it fills gaps that larger station-type power packs cannot — particularly on mobile plant, chassis-mounted equipment, and compact production machinery where every litre of installation volume matters.
Related Hydraulic Cylinder Products
If you are specifying a complete hydraulic circuit for your UK application, the following cylinders are commonly paired with this power unit:
Wind Power Hydraulic Cylinder – 100mm Bore, 80mm Stroke
Designed for pitch and yaw control in wind turbine installations, this cylinder’s 100 mm bore and 80 mm stroke specification pairs naturally with the compact power unit’s 21 MPa rated output.
Grain Tank Lift Cylinder — Double-Acting, 65mm Bore, 607mm Stroke
A double-acting cylinder designed for combine harvester grain tank unloading systems. The 65 mm bore and 607 mm stroke deliver the force and travel needed for reliable tank lid actuation in UK harvest conditions.
Customer Success: Real Applications Across the UK and Europe
Over the past decade, these compact hydraulic power units have been supplied to OEMs and end users across a range of industries. Three representative projects illustrate the breadth of application and the reliability record that B2B purchasers in the UK have come to expect from this platform.
Automotive Aftermarket
Vehicle Lift Retrofit Programme — 28 Lifts, 12 Dealerships
A regional automotive service chain operating across the West Midlands needed to upgrade the hydraulic power packs on 28 two-post vehicle lifts as part of a noise-reduction initiative driven by local authority planning conditions. The existing units exceeded 80 dB under load. After trialling three alternatives, the facilities manager selected this compact hydraulic power unit at the 1.5 kW AC / 380 V configuration. Post-installation measurements consistently read below 68 dB — well within the 70 dB operating ceiling and comfortably inside the planning condition threshold. The aluminium manifold’s lighter weight also simplified the roof-mount installation in bays with restricted ceiling clearance.
“We benchmarked four suppliers before placing the order. The noise figures were the deciding factor, but the 200-plus circuit options also meant our installer could configure the valve pack to match our existing manifolds without bespoke machining.”
— Facilities Procurement Manager, West Midlands automotive group
Agricultural OEM
Grain Cart Tipping Systems — Series Production Integration
An East Anglian agricultural machinery manufacturer producing grain carts for the UK and Benelux markets required a power pack that could tolerate vibration, ingress of dust and chaff, and ambient temperatures ranging from -5°C during late autumn harvest to 38°C during summer rape cutting. The 24 V DC / 0.8 kW configuration was chosen for its compatibility with the standard 12/24 V tractor auxiliary circuit. Units have been fitted across three model years of grain cart production — over 340 units in the field — with zero warranty returns attributable to the power pack itself. The zero-leakage cartridge valves were specifically cited by the engineering team as the reason for adopting this platform over a competing unit that suffered load-drift complaints.
“Three seasons of harvest with zero hydraulic warranty claims. That is not something we expected when we switched suppliers. The cartridge valve pressure-holding performance is genuinely better than anything we used previously.”

Logistics & Material Handling
Automated Dock-Leveller Replacement — Distribution Centre, Cardiff
A third-party logistics provider operating a 42-bay distribution centre in Cardiff replaced an ageing fleet of dock-leveller power packs as part of a capital maintenance programme. The site operates two shifts daily, with levellers cycling approximately 180 times per bay per week. Energy consumption was a critical KPI: the previous hydraulic units had been identified in an energy audit as a significant contributor to the site’s electricity bill. The 380 V AC / 1.1 kW configuration was selected, paired with a pressure-maintaining circuit that holds position between dock cycles without running the motor continuously. Measured energy reduction was 23% compared to the previous installation, validated over a 90-day monitoring period by the site’s energy manager.
“The payback on the capital cost was 14 months based on energy savings alone. We have now standardised on this power unit across all four of our UK sites.”
— Operations Director, 3PL provider, South Wales
Factory & Custom Configuration Capability
The compact hydraulic power unit is manufactured in a purpose-built facility equipped with CNC valve-block machining centres, automated gear pump assembly lines, and a pressure-test station capable of certifying units to 1.5 times the rated working pressure. Every unit shipped to UK customers is tested and documented before despatch. Beyond the standard range, the facility has a dedicated custom engineering team that works directly with OEM procurement and engineering departments to develop project-specific configurations. Customisation options include non-standard port threads (including BSP threads for UK legacy installations), bespoke reservoir capacities, custom mounting foot and bracket arrangements, special motor shaft configurations, painted or powder-coated tank finishes, and circuit designs not available from the standard valve combination catalogue. UK customers requiring CE marking documentation or PSSR 2000 compliance data packages should request this at the quotation stage — it is supplied as a matter of course for export to the British market.
