Hidroman designs and manufactures custom hydraulic power units and hydraulic power systems for a wide range of industrial applications. Each solution is developed around the machine's operating requirements, with carefully selected pumps, motors, valves, filtration components and control equipment.
Using modern 3D design technology and application-focused engineering, Hidroman develops hydraulic power units with consideration for performance, installation requirements, maintenance access and system reliability.
Whether you need a bespoke hydraulic power pack for a single machine or an integrated hydraulic solution for industrial equipment, Hidroman works with you to identify a suitable configuration for your application.
Every hydraulic application has different pressure, flow, duty cycle, temperature and installation requirements. Selecting the right hydraulic power unit involves more than simply combining standard components. The system must be correctly sized and configured for its intended operating conditions.
Hidroman evaluates the technical requirements of each project to help determine an appropriate hydraulic power unit configuration.
Key design considerations include:
Required operating pressure and flow rate
Electric motor power and hydraulic pump capacity
Reservoir volume and hydraulic oil management
Directional control, pressure control and safety valves
Pressure-line and return-line filtration
Oil cooling and heating requirements
Oil level and temperature monitoring
Installation dimensions and machine interfaces
Maintenance access and service requirements
A properly engineered hydraulic power unit can help improve operating efficiency, support reliable machine performance and reduce unnecessary energy consumption and maintenance costs.
The performance of a hydraulic power unit depends on selecting compatible components that meet the application's technical requirements. The final configuration can include a combination of hydraulic, mechanical and electrical equipment.
Electric motors provide the drive for hydraulic pumps. Depending on the required pressure, flow rate and operating characteristics, gear pumps or axial piston pumps can be considered.
Pump displacement, motor power and operating speed must be matched to the system's requirements to achieve the intended performance.
Directional control valves, pressure control valves and screw-in cartridge valves regulate hydraulic flow and pressure within the system.
Depending on the application, CETOP 3 and CETOP 5 valve configurations can be incorporated into the design. Valve selection is based on the required flow capacity, operating pressure, control functions and installation arrangement.
Hydraulic oil cleanliness is an important factor in protecting pumps, valves and other sensitive components. Pressure-line and return-line filters can be selected according to the system's cleanliness requirements and operating conditions.
Additional filtration and oil transfer solutions can also be considered where the application requires them.
Hydraulic oil temperature affects fluid viscosity, component performance and system reliability. Depending on the thermal load and operating environment, a hydraulic power unit may incorporate an air cooler, water cooler or oil heater.
The appropriate configuration should be determined from the system's heat generation, operating cycle and ambient conditions.
Hydraulic power units can be equipped with oil level indicators, temperature monitoring devices, pressure sensors, analogue transmitters and electrical control components.
Motor safety switches and terminal arrangements can also be incorporated according to the machine's electrical and operational requirements.
Reservoir dimensions, pipework, drip trays and the supporting frame can be configured to suit available installation space and machine interfaces.
Depending on the project, options may include compact or elongated layouts, different electric motor mounting arrangements, raised mounting feet and standard or customer-specific paint finishes.
Hidroman offers hydraulic power unit configurations tailored to individual project requirements. Depending on the application, the design can be based on modular components or a fully bespoke arrangement.
Modular hydraulic power packs can simplify component selection, assembly and maintenance where standardised configurations are suitable. Bespoke hydraulic power units are particularly useful when a machine requires a specific footprint, unusual connections, dedicated control functions or integration with existing equipment.
The design process considers not only hydraulic performance but also accessibility, installation constraints and the practical needs of maintenance personnel.
Custom hydraulic power units are used across industries where controlled hydraulic power is required to operate machinery, actuators and production equipment.
Hydraulic power packs can be designed for presses, production lines and heavy-duty industrial machinery, subject to the pressure, flow and duty-cycle requirements of each application.
Mining machinery and heavy industrial equipment may require robust hydraulic power systems designed around demanding operating conditions, machine interfaces and service requirements.
Special-purpose hydraulic power solutions can be developed for selected mobile equipment and attachment applications, taking account of available space, operating characteristics and control requirements.
Hydraulic power units can supply the hydraulic energy required for machine movements, clamping systems, production equipment and other industrial automation applications.
Dedicated hydraulic power units can be incorporated into test rigs, service equipment and hydraulic component testing systems, according to the required test pressure, flow and control functions.
For OEMs and machine builders, bespoke hydraulic power packs provide an option when an off-the-shelf unit does not meet the required dimensions, performance characteristics or integration needs.
Each application should be assessed individually to determine the appropriate system configuration.
Reliable hydraulic equipment requires appropriate engineering, assembly practices and technical documentation. The documentation supplied with a hydraulic power unit depends on the agreed project scope and applicable requirements.
Depending on the project, documentation may include:
Hydraulic circuit diagrams
General arrangement and dimensional drawings
Component and spare parts lists
Operating and maintenance instructions
Installation and handling instructions
Electrical schematics and control documentation
Applicable conformity documentation
For projects supplied to European customers, conformity assessment and documentation should be determined according to the intended use, the machinery configuration and the legislation applicable to the final equipment.
This approach helps OEMs and industrial operators plan installation, commissioning, maintenance and future servicing.
Hidroman combines hydraulic engineering experience with application-specific design and component selection to develop solutions for industrial customers.
Key advantages include:
Hydraulic power unit design tailored to the application
Modern 3D design technology
Component selection based on technical requirements
Modular and bespoke construction options
