Compact Hydraulic Power Pack
Reduced-footprint hydraulic power source engineered for confined work areas, mobile equipment integration, and sites where standard skid-mounted power packs cannot be positioned
The Compact Hydraulic Power Pack is a reduced-footprint hydraulic power source designed for work areas where standard skid-mounted units cannot be positioned. The unit integrates a 5.5 kW air-cooled gasoline engine with a variable-displacement hydraulic pump rated at 28 L/min and 210 bar, a 10-litre reservoir with 10-micron filtration, and two sets of flat-face quick couplers. The frame measures 520 x 480 x 380 mm and weighs 38 kg dry, allowing the unit to be carried by two operators or moved on its integrated wheels through doorways, lift access, and confined plant rooms. Because the power source is an engine rather than an electric motor, the unit operates independently of mains electricity and can be used in areas without temporary power. The pressure-compensated pump reduces flow when downstream demand falls, limiting heat generation in the smaller oil volume. The unit is suited to procurement by maintenance contractors, mobile equipment integrators, and service fleets requiring a hydraulic power source that fits within restricted spaces.
The unit supplies 28 L/min at 210 bar, which matches compact breakers, cutters, spreaders, torque wrenches, small cylinders, and pullers operating within that flow and pressure range. Tools requiring higher flow or pressure cannot be driven correctly. Buyers should provide the tool specification at inquiry stage so the pump displacement and relief setting can be confirmed before shipment.
The 10-litre reservoir is smaller than on standard skid units, which suits intermittent tool use and short duty cycles. The pressure-compensated pump reduces flow when demand falls, limiting heat generation within the reduced oil volume. For continuous operation with high-flow tools, buyers should confirm the duty cycle against the oil volume and cooling arrangement, as sustained high-flow operation may require a unit with a larger reservoir.
The frame measures 520 x 480 x 380 mm and weighs 38 kg dry, allowing two operators to carry it through standard doorways and up stairwells. The integrated wheels allow movement on flat surfaces. Buyers should confirm the actual doorway widths and any stairwell or lift constraints along the access route before ordering, as these determine whether the compact configuration is suitable for the intended work area.
The compact frame and 38 kg dry weight allow the unit to be mounted on service vehicles and mobile work platforms where a standard skid unit would exceed available space or payload limits. Buyers should confirm the mounting arrangement, payload limits, and vibration isolation requirements. Mounting provisions can be adapted at order stage, and the dimensional drawing should be reviewed against the vehicle layout before finalising the specification.
The 3.6-litre fuel tank provides approximately 2 hours at rated load, depending on engine load and operating conditions. Because the pump is pressure compensated, fuel consumption falls when tools are idle or operating at partial demand, and runtime can extend beyond this figure in intermittent use. Buyers should confirm refuelling arrangements for their expected duty cycle.
Check engine oil level before each use, and clean or replace the air filter according to the operating environment. Inspect hydraulic hoses and couplers for abrasion or leakage, and check the reservoir oil level. Hydraulic oil and return filter should be replaced at the interval specified in the maintenance schedule. For units in standby, run the engine briefly each month to confirm operation.
A complete inquiry should include: the tools or equipment to be driven, with flow and pressure requirements; the access route dimensions, including doorway widths and lift or stairwell constraints; the expected duty cycle and runtime per shift; whether the unit will be vehicle-mounted, with mounting arrangement details; and the required coupler type and hose length. For fleet procurement, indicate the estimated quantity and whether the specification must remain fixed across repeat orders.
