Ronzio Oleodinamica

What Ronzio Oleodinamica does

Ronzio Oleodinamica S.p.A. is an Italian family-owned manufacturer of hydraulic components, founded in 1954 by Dante Ronzio and now led by second and third generation family members (Francesca and Giulia Ronzio). Headquartered in Boffalora sopra Ticino near Milan, the company designs and produces a comprehensive portfolio of gear pumps, hydraulic motors, and flow dividers — including the proprietary zero-backlash AP series (up to 470 bar), the low-noise EVO and Q-series cycloidal pumps, standard aluminum and cast iron Z/W series pumps, agricultural pumps (PD, PN), truck pumps (NF series), and specialized products such as fan drives and customized engineered solutions. All products are manufactured entirely in Italy at the Boffalora facility and are ISO 9001:2015 certified by DNV.

The company sells through a hybrid go-to-market model combining direct sales from Italy and a dedicated US subsidiary (Buffalo Fluid Power, Burnsville, Minnesota) with a global network of authorized distributors across at least 11 countries spanning North America, Europe, Asia, and Oceania. Its customer base spans eight industrial verticals — earth-moving and construction, agricultural machinery, industrial vehicles, lifting and transport, mining, shipbuilding, forestry, and industrial plants — with no concentration in any single segment.

Ronzio generates revenue exclusively through hardware sales of hydraulic components, with pricing determined per-specification based on volumes and customization requirements; no public pricing or revenue figures are disclosed. The company competes on engineering depth, proprietary tooth profile geometries, volumetric efficiency (95-97%), and 70+ years of 'Made in Italy' brand reputation, supported by partnerships with Politecnico di Milano and Italian technical institutes for engineering talent development. No external funding rounds, parent company, or M&A activity have been disclosed.

Products and services

• AP-Series High-Pressure Pumps and Motors High-pressure pumps and motors with cast iron housings and zero-backlash tooth profiles for reduced noise and pressure pulsations. AP3 supports up to 470 bar maximum intermittent pressure and AP4 supports up to 400 bar maximum intermittent pressure, intended for demanding industrial hydraulic systems.
• Q-Series Cycloidal Silent Pumps Silent cycloidal pumps featuring an innovative tooth profile designed for low-noise, high-efficiency operation at low rotational speeds. Available in 11, 14, 17, and 20 cm³/rev displacements and rated for up to 280 bar maximum continuous operating pressure.
• EVO-Series Low-Noise Pumps Low-noise pumps with cast iron covers and body using a zero-backlash gear tooth profile to reduce noise and oil pulsations. EVO 3 covers displacements from 30 to 80 cm³/rev; EVO 4 covers displacements from 75 to 150 cm³/rev for heavy-duty applications.
• Z-Series Standard Aluminum Pumps and Motors Standard aluminum pumps and motors with cast iron and aluminum covers. Z1 covers displacements from 0.8 to 10.5 cm³/rev with integrated valves; Z2 covers 4 to 31 cm³/rev with cast iron covers for high performance; Z3 covers 20 to 80 cm³/rev up to 280 bar continuous pressure.
