Core product categories include hydraulic cylinders for civil engineering (dams, flood protection, ship locks, hydroelectric stations), hydraulic presses (forging, forming, bending), steel works and aluminium plants, offshore and wave-energy platforms, surface and underground mining, bridge construction, power generation, and general mechanical engineering, plus a Standard Hydraulic Cylinders line (telescopic, tie rod, steel works standard, standardnorm). Proprietary technology assets include Hunger DFE seals and bearing elements, the Ceraplate corrosion-resistant piston-rod coating, and the Hunger Drive High Performance Electro-Hydraulic Drive System.

The firm operates as a German GmbH & Co. KG (limited partnership), with WH Vermögens-Verwaltungs-GmbH as the personally liable shareholder and Dr. Jan Hunger (Dipl.-Ing. Dipl.-Wirtsch.Ing.) as Managing Director. Its go-to-market is enterprise field-sales with technical consultation from first inquiry through commissioning and maintenance, supported by project references, downloadable PDF specifications, and industry trade events. Reported customers include NASA (Crawler Transporter cylinders), ThyssenKrupp (bucket-wheel excavator jacks), Canary Wharf (London bridge cylinders), Yimin He Open Pit Mine, Lower Colorado River Dam, St. Petersburg flood protection, Oyster Wave Energy plants, and an extensive list of named dams (Aswan II, Guri, Tarbela, Sardar Sarovar, Atatürk, and others). The company is ISO 9001:2015 certified for development, manufacture and distribution of hydraulic cylinders of all sizes, and operates across approximately 35 countries.

Revenue mechanics are project- and specification-based for custom cylinders, supplemented by catalog sales of standard series, with all production and testing performed in-house in Germany. The business shows no external institutional investors, no public listing, and no disclosed acquisitions or fundraising activity in the source data.

Core offering

Walter Hunger designs and manufactures custom-made hydraulic cylinders and the proprietary Hunger Drive electro-hydraulic drive system for extreme industrial applications. Production is performed and tested entirely in-house in Germany, covering application-specific cylinders for civil engineering, mining, offshore, steel and aluminium plants, bridge building, powerplants, hydraulic presses, and mechanical engineering, alongside a Standard Hydraulic Cylinders product line. The company provides full technical consultation from initial inquiry through project completion and maintenance.

Product overview

Walter Hunger GmbH & Co. KG Hydraulikzylinderwerk is a German industrial manufacturer specializing in custom hydraulic cylinders and drive systems. The product portfolio centers on the Hunger Drive High Performance Electro-Hydraulic Drive System and encompasses both application-specific hydraulic cylinders (for plant building, aluminium plants, steel works, bridge building, powerplants, mechanical engineering, offshore, hydraulic presses, civil engineering, and surface/underground mining) and a Standard Hydraulic Cylinders product line. The standard cylinder line includes telescopic cylinders (HHN 810), tie rod cylinders (HHN 815/816), steel works standard cylinders (HHN 811/812/814), and standardnorm cylinders (HHN 805/813), covering pressure ranges from 105 bar to 350 bar with diameters up to 320/220 mm. All products are manufactured and tested in-house in Germany, with capabilities including forces up to 10,000 tonnes per cylinder for press applications.

Direct peers

• HAWE Hydraulik: German manufacturer of hydraulic components and systems including high-pressure cylinders, valves, and power packs for presses, offshore, and heavy industrial applications. Highly comparable to Hunger as a German specialist in custom high-pressure hydraulics with overlapping end markets in presses, steel works, and offshore.
• Wipro Infrastructure Engineering (Hydroline): Acquired the Hydroline brand and manufactures hydraulic cylinders for heavy mobile equipment, agriculture, and material handling. Comparable on custom and series hydraulic cylinders for industrial OEMs, with growing presence in demanding applications similar to Hunger's customer base.
• AHP Merkle: German manufacturer of standard and custom hydraulic cylinders (tie-rod, telescopic, block cylinders) for industrial, mobile, and offshore applications. Closely comparable German specialty competitor with similar Made-in-Germany positioning and project-engineered custom solutions.
• Enerpac: Specialist in high-force hydraulic tools, cylinders, and presses serving heavy lifting, maintenance, infrastructure, and energy markets. Comparable to Hunger in the high-force cylinder and press niche, with particular overlap in civil engineering, power generation, and offshore.
• HYDAC International: German-based global supplier of hydraulic accumulators, cylinders, valves, filters, and fluid conditioning for heavy industry, mining, offshore, and mobile machinery. Direct peer in custom-engineered hydraulic systems for extreme applications, particularly offshore and marine.

Broad incumbents

• Eaton: US-based power management company with a hydraulics business (now part of Danfoss Power Solutions) producing cylinders, valves, and pumps for industrial and mobile equipment. Competes with Hunger in high-force custom cylinders for presses, mining, and infrastructure.
• Bosch Rexroth: One of the world's largest fluid power and motion control suppliers, offering hydraulic cylinders, drives, and complete systems across industrial, mobile, and factory automation applications. Broadly comparable to Hunger as a high-end hydraulic cylinder manufacturer but at vastly greater scale and with a much wider product portfolio.
• Parker Hannifin: Global motion and control technologies company with a substantial hydraulic cylinder product line serving industrial, aerospace, and mobile equipment markets. Comparable on custom and standard hydraulic cylinders for heavy industry, though Parker operates at significantly larger scale and breadth.
• Liebherr (Components division): Manufactures hydraulic cylinders in-house for its own construction, mining, and maritime equipment, and supplies cylinders externally for heavy mobile applications. Comparable to Hunger on high-force cylinders for mining excavators, crawler cranes, and offshore equipment.

Emerging players

• Holmatro: Dutch manufacturer of high-pressure hydraulic cylinders, rescue tools, jacks, and industrial systems. Comparable on high-force hydraulic actuation for industrial, marine, and infrastructure customers, though with a stronger focus on rescue and tool applications.
