Hydraulic power units

Hydroservice develops custom hydraulic power units for industrial, energy, petrochemical, oil & gas and offshore applications, supporting customers from technical requirements to commissioning and long-term service.

Hydraulic blocks

Hydroservice panels are monobloc and modular hydraulic blocks, designed for the mounting of CETOP03, CETOP05, CETOP07 and CETOP08 valves – in customised configurations. Thanks to the ability to link blocks from the same series — ranging from compact GN06 sizes to high-flow GN25 sizes — it is possible to construct complex control circuits starting from individual components: base panels, intermediate modules, pressure and flow regulators, accumulator connections, shut-off and short-circuit plates, as well as conversion plates for different sizes. Manufactured from hydraulic cast iron or carbon steel with a phosphated finish, Hydroservice panels cover a pressure range up to 315–350 bar and flow rates up to 400 l/min, ensuring reliable hydraulic sealing and reduced assembly times compared to traditional piped circuits.

Wood Processing

Hydraulic system for command and control of continuous press for forming impregnated wood panels

Design and implementation of two plants for the same line for the control of a continuous woodworking press, through which wood panels are produced for various sectors.

On-shore

90 compact hydraulic blocks

The challenge: To design a hydraulic block that was as compact as possible, so that the cabinet intended to house it was of limited size, and to make 90 copies of it. Reducing the footprint also means reducing weight and costs. We succeeded by betting everything on three pillars: the passion for what we do, our experience and teamwork.

Hydroelectric

Design of hydraulic group with hydraulic panel for rotary valve control

The Castelbello hydroelectric power plant uses water from the Adige River and its tributaries to produce clean energy-our HPU is designed to support all of its operations.

Presses

Environment

A constant commitment

Knowledge of and compliance with health and safety regulations is a priority for everyone who works for or with us. We encourage responsible behaviour to safeguard the health and safety of our employees, partners and collaborators. A strong sense of ethics, respect for individuals, professionalism, transparency and reliability are the values that guide us and that we promote amongst everyone working with Hydroservice.

Security

Systems designed to eliminate risk

Hydroservice supports its customers in developing hydraulic command and control systems already compliant with the essential health and safety requirements (RESS) of the New Machinery Regulation (EU) 2023/1230, which replaces the Machinery Directive 2006/42/EC as of 20 January 2027, ensuring that any hardware, software or system failures do not create hazardous situations for the operator.

Security

What we evaluate for each safety circuit

CCF (Common Cause Failure) — Circuit robustness against a common cause of failure, calculated based on technology, architecture, application type and operating environment. MTTFd (Mean Time to Failure Dangerous) — Average lifespan of a component before a dangerous failure occurs; used to derive the dangerous failure rate (λd). B10d — Average number of cycles before a dangerous failure; requires defining the machine's operating cycle, running hours and frequency of use. DC (Diagnostic Coverage) — Diagnostic coverage that the control system performs on the components executing the safety function. At the end of the design process, Hydroservice issues the calculation report for the achieved Performance Level [PL], to be included in the machine's technical file to document compliance with the requirements of the Regulation.

About us

What guides us in every project

Security

From risk analysis to performance level

The applicable harmonised standard is UNI EN ISO 13849-1:2023, which defines the design requirements for safety-related control and command circuits (SRP/CS). Drawing on its expertise in hydraulics and mechatronics and using certified software, Hydroservice selects architectures and components suitable for achieving the required safety function.Support covers the entire engineering phase: from the analysis of applicable product standards and the preparation of the risk assessment, through to the selection of certified components to achieve the Performance Level (PL) defined by the standard.
