Believing that WE can succeed

Taking the LEAD in our present

Working TOGETHER for our future



Using modern 3D design processes, combined with the specific expertise of a highly qualified technical team, each complex systems project takes shape through constant dialogue with the customer.
Our consolidated working method allows us to optimise every design phase, achieving a result that meets the expectations of the customer and which is tailored for the specific application.
Detailed analysis of applicable legislation and order specifications ensures that every power unit, manifold or cabinet is created in compliance with the strictest requirements and specifications.



We combine the efficiency of modern industrial processes with the passion and attention that an artisan adopts in every single aspect of their work.
Assembly is simplified for easier replacement of any part during maintenance.
Coating processes are handled in-house, with a range of colours, all guaranteeing compliance and high-performance in terms of coverage, durability and health and safety.
We also work with carefully selected certified suppliers, particularly for more extreme coating cycles.


A complete service tailored to customer requirements, from customised design through to approval testing of the complete system and subsequent maintenance, guaranteeing the reliability, quality and efficiency of our projects.

Approval testing


Checks and final approval testing are an essential stage in production.
This process involves a detailed and mandatory checklist, ensuring that every system has a declaration of compliance.
We are pleased to be able to invite our customers to attend during the approval testing stage, allowing them to verify that the system meets all established requirements in person.


​LAST BUT NOT LEAST: Maintenance and servicing


Expertise is evaluated not only when the ideas for an advanced engineering project take shape but also when the ideas for the hydraulic power unit become reality and, above all, as the conditions of the installation change over time. We support our customers throughout product conception and the creation of a complex hydraulic system, but above all once it is operational and needs care in the future. Do you need to renew or upgrade an existing hydraulic solution to extend its working life? Our qualified team can help you anywhere in the world, supporting you in redefinition of the design of your entire hydraulic system. We don’t only offer new products. We also help you to identify solutions to your issues and requirements regarding power units, manifolds and cabinets.

Our goal is to become a player of excellence in the design and manufacturing of complex solutions for motion control and industrial automation, thanks to updated technology used for our solutions and a prompt and proactive pre- and post-sales service.
