What Hydraulik-Service Rhein-Ruhr does

Hydraulik-Service Rhein-Ruhr GmbH is a privately held German industrial services company founded in 1979 and headquartered in Oberhausen, operating in the Ruhr industrial region. The company specializes in the brand-independent repair and overhaul of hydraulic components — pumps, motors, valves, and cylinders — for industrial customers, with all repaired components undergoing 100% performance testing on in-house test stands and warranty terms equivalent to new OEM components. Its service portfolio spans four core repair lines (hydraulic pump/motor repair, valve repair, cylinder repair, and dedicated press servicing), supplemented by a 24-hour/365-day emergency repair hotline, custom hydraulic aggregate manufacturing through partner HYMA Erfurt GmbH, and new-parts supply from major OEMs including Bosch-Rexroth, HOERBIGER, and Parker ORIGA.

The company serves enterprise industrial customers across manufacturing, steel production, offshore/maritime, and defense verticals, with documented work ranging from automotive press transfer lines and steel continuous casting plants to offshore vessel hydraulic systems deployed internationally. It maintains ISO 9001:2015 quality management certification (since 1997) and WHG §19 water-resources certification. The business is owner-operated by managing directors Janine Herberger-Wolters (controlling, quality, environmental management) and Thomas Wolters (sales, production, technology), with no external investors, no parent company, and no disclosed funding rounds. The go-to-market model is direct enterprise field sales with on-site technical consultation and emergency response, supported by trade show presence (EuroBLECH 2012-2018) and multilingual technical documentation. Revenue is not publicly disclosed; pricing is quote-based per repair or service requirement.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Bosch Rexroth: Global leader in hydraulic components and factory automation, with an extensive OEM service network and authorized service partners. Comparable because HSRR is a brand-independent repair specialist that services Bosch-Rexroth products (A4VSO, A10VSO, 4WRE, etc.) and also resells their new parts. The two operate in the same hydraulic value chain but at different layers (OEM vs. independent MRO).
• Parker Hannifin: Global motion and control technologies leader with a massive hydraulic systems division including cylinders, pumps, valves, and filtration. Parker is both an OEM partner to HSRR (via Parker ORIGA) and a competitor in industrial hydraulic service. Operates authorized service centers worldwide with deep technical capabilities.
• HOERBIGER: Global manufacturer of compression technology, automation, and hydraulic components with service operations. Both HOERBIGER Automatisierungstechnik and HOERBIGER Micro Fluid are HSRR partners for new parts supply, making HOERBIGER a comparable hydraulic supplier with its own service network.
• Moog Industrial: Global manufacturer of high-performance motion control products including hydraulic servo valves and systems. Service and repair of Moog valves is a known HSRR capability (referenced in press services). A broader incumbent in hydraulic service operations, especially in industrial presses and steel.

Direct peers

• HYDAC International: German-headquartered global manufacturer and service provider for hydraulic components, filtration, fluid conditioning, and electronic controls. HYDAC has a strong service and repair network across hydraulic systems, making it a direct competitor in industrial hydraulic MRO services across Europe and beyond.
• HAWE Hydraulik: German manufacturer of hydraulic components, pumps, valves, and power units, with associated service and repair capabilities. Comparable to HSRR as a German hydraulic specialist with overlapping product categories (valves, pumps, cylinders) and a focus on industrial hydraulic system maintenance.
• Linde Hydraulics: Manufacturer of hydraulic pumps and motors for mobile and industrial applications, offering service and remanufacturing for its products. Comparable to HSRR because it specializes in hydraulic pump and motor repair/remanufacturing with similar brand-independent value propositions for industrial customers.
• Bucher Hydraulics: Swiss manufacturer of hydraulic pumps, valves, power units, and cylinders with European service and repair operations. Comparable to HSRR as a European specialist in hydraulic component repair and OEM supply, with overlapping product categories in pumps, motors, and valves.
• Atos (Hydraulics): Italian manufacturer of hydraulic proportional valves, cylinders, and systems with a service network across Europe. Comparable to HSRR as a specialist hydraulic component manufacturer and service provider targeting industrial customers, with a similar emphasis on proportional and directional valves.

Others

• HYMA Erfurt GmbH: German hydraulic power unit and aggregate manufacturer with international service capabilities. HSRR's partner for custom hydraulic aggregate manufacturing, HYMA is a thematically related company rather than a direct competitor, but operates in the same German hydraulic MRO ecosystem.
