Group 0.5 DC · micro hydraulic power packs
The compact 12/24V micro power pack: maximum power in minimum space.
Page maintained by the Gazzera Srl engineering team, updated .
When space is the toughest spec, whether a chassis recess, a stabiliser leg or an on-board actuator, the group 0.5 micro power pack does a big unit’s job in a fraction of the footprint. Pressures remain high (up to 230 bar): what changes is flow, suited to short movements and concentrated loads. Horizontal and vertical layouts, including integration into the customer’s equipment.
Micro sizing is unforgiving: small margins on reservoir and cooling demand a well-defined duty cycle. This is the line where experience counts most, and where the advantage of talking directly to the manufacturer shows from the first production batch.
Up to 230 bar continuous, peaks above 250 bar
More displacement means more flow but a lower maximum pressure: high pressures come from small displacements.
| Pump | Displacement (cm³/rev) | Max continuous pressure |
|---|---|---|
| Group 0.5 | 0.88 and 1 | 230 bar |
What the customer needs is force, not pressure. A Ø50 cylinder at 210 bar pushes about 41 kN (just over 4 tonnes); a Ø63 cylinder gives the same force at 130 bar, about 40 kN. When you need both force and speed, the cylinder bore is the lever.
Typical industries
Components compatible with this line
Hydraulic pumps
Gear pumps for compact power packs: a wide displacement range for every flow/pressure combination.
Electric motors
Single/three-phase AC and 12/24V DC motors coupled to the pump via dedicated kits, for continuous or intermittent duty.
Manifolds
Aluminium manifolds for compact power packs, machined to drawing with configurable cavity count.
Reservoirs
Plastic and steel reservoirs, horizontal and vertical, from 1.5 to 30 litres, with dedicated plugs and accessories.
Suction & return
Suction and return kits matched to the reservoir: strainers, filters and fittings sized to pump flow.
Valves & plugs
Relief, check and lowering valves plus plugs for complete power pack circuit control.
Function plugs
Cartridge function plugs for manifold cavities: they seal the cavities the circuit does not use or give them a function, such as a 1/4" BSP port.
Frequently asked questions
When do you choose group 0.5?
When space is the toughest spec. The micro power pack does a big unit’s job in a fraction of the footprint, with pressures up to 230 bar and modest flows for short movements.
What pumps and reservoirs does it use?
Group 0.5 pumps of 0.88 and 1 cm³/rev and plastic reservoirs of 1.5 and 2.5 litres, with 12/24V DC motors from 0.5 to 0.8 kW.
Can I integrate it into the equipment?
Yes: horizontal and vertical layouts are available, including integration into the customer’s structure. Micro sizing needs a well-defined duty cycle, which we verify at quotation.
