Founded in 1954 by Dante Ronzio, Ronzio Oleodinamica S.p.A. is now a reference point in the design and production of pumps, motors, flow dividers, and components for hydraulic systems.
Our company is family-run and combines tradition with innovation, bringing the excellence of Made in Italy to the global market.
Over the years, we have developed a dynamic and streamlined structure that allows us to meet customer needs with customized solutions, high quality, and reliability.
The second and third generations of the Ronzio family — including Francesca and Giulia — are now actively involved in continuing our commitment to internationalization, innovation, technology, and research.
Through constant investment in R&D, we strive to deliver innovative solutions and maintain the highest standards in production and customer service, earning the trust of partners worldwide.
Ronzio Oleodinamica S.p.A. relies on a team of highly specialized engineers dedicated to the development and optimization of gear pumps and motors for a wide range of hydraulic applications.
In addition to our standard production, our technical department is focused on custom design, offering tailor-made solutions to meet the specific requirements of each customer. Every project starts with an in-depth technical dialogue and develops through structured phases of analysis, 3D modeling, fluid dynamic simulation, and functional validation.
Our design approach is based on:
Decades of experience in applied hydraulics
Use of advanced CAD tools and FEM software (Finite Element Method) to ensure precision and reliabilityto ensure accuracy and reliability;
Active collaboration with the customer from the concept phase up to series production;
Continuous update in line with the technological and regulatory developments in the market.
Through field testing, customer feedback, and rigorous quality controls, we continuously refine our products to ensure maximum efficiency, durability, and performance—even in extreme working conditions.
At Ronzio, design is more than just engineering—it’s about transforming technical needs into efficient, long-lasting solutions, translating technical requirements into solutions that are practical, efficient, and durable.
All Ronzio Oleodinamica S.p.A. products are 100% Made in Italy, manufactured entirely at our headquarters in Boffalora sopra Ticino, where every stage of the production process is carefully monitored and controlled.
The success of our gear pumps and motors is driven by a solid combination of key factors:
Selected raw materialsof the highest quality;
Skilled laborwith technical skills with time-proven;
Continuous investment in advanced technologies, state-of-the-art machinery, and industrial automation
Thanks to a production process and integrated, we are able to ensure the total control, traceability and flexibilityby responding quickly to market needs and maintaining high quality standards.
With over sixty years of manufacturing experience, we continue to build products that are reliable, efficient, and ready to meet the challenges of modern industry.
At Ronzio, tradition and innovation come together to shape the future of hydraulics.
Within our production site is active, a department dedicated exclusively to the quality controlwith the objective of ensuring for maximum accuracy, repeatability and compliance the technical requirements demanded by the customers.
Thanks to state-of-the-art metrology equipment, 3D coordinate measuring machines (CMM), and advanced control software, we continuously monitor the entire production process in real time, enabling prompt corrective actions when necessary.
Each component is tested the dimensional, mechanical, and functionalto ensure strict compliance with the required parameters, in terms of:
