What Jihostroj does

Jihostroj a.s. is a Czech precision engineering manufacturer founded in 1919 and headquartered in Velešín, Czech Republic, operating from a single campus that combines two core product divisions — Aerospace and Hydraulics — with three supporting service operations in surface treatment (galvanizing), heat treatment, and tool making. The Aerospace division produces safety-critical aircraft components including fuel pumps and motor control systems, APU and GPU fuel regulation systems, propeller speed governors (mechanical and electronic eRegulátory variants with DC micromotor control), and a broad airframe portfolio of over 20 qualified valves, pumps, filters, and distribution components (e.g., LUN 7707 pressure refueling valve, LUN 7460 float valve, LUN 7464 fire valve, FNG-12 fuel filter, BP-DCA transfer pumps). The Hydraulics division manufactures hydraulic pumps, motors, and aggregates for agricultural and industrial machinery, with customizable displacement, shaft, and connection configurations. Underpinning both divisions are in-house surface treatment (anodizing, plating, painting, ASTM B117 salt spray corrosion testing), a four-furnace heat treatment cell (SOLO 600, SOLO 300, SECO/WARWICK vacuum, EBNER 650°C), and a tool shop producing fixtures, jigs, gauges, and precision tooling.

The company's business model is a quotation-based B2B direct sales operation conducted through division-specific sales contacts ([email protected] for Hydraulics, [email protected] for Aerospace), with EXW delivery from Velešín, a EUR 50 minimum order, and bespoke manufacturing against customer specifications; a secondary e-commerce catalog channel with consumer-grade 14-day withdrawal rights extends the model to smaller and individual buyers. Quality management is anchored in AS9100D/ISO 9001 aerospace certification, a zero-tolerance Code of Conduct on airworthiness and counterfeit parts, and a Czech Ministry of Industry and Trade license for foreign trade in military materiel under Act No. 38/1994 Sb., supporting both civil aerospace and defense/dual-use export programs. Jihostroj is a private joint-stock company wholly owned by JAWAUNION s.r.o., sits within the JAWAUNION corporate group alongside subsidiary JISTRO s.r.o., and operates with a workforce of 397 employees across approximately 19,500 m² of dedicated production floor.

Core offering

Jihostroj a.s. designs and manufactures precision-engineered aerospace fuel system components (engine fuel pumps, motor control units, APU/GPU fuel regulation systems, propeller speed governors, and airframe fuel/hydraulic valves and filters) as well as hydraulic pumps and motors for agricultural and industrial machinery. Manufacturing is vertically integrated with in-house galvanic surface treatment, multi-furnace heat treatment, and a dedicated tool shop producing fixtures, gauges, and custom precision tooling.

Product overview

Jihostroj operates two core product divisions: Aerospace and Hydraulics. The Aerospace division produces fuel system components including fuel pumps, control units, propeller governors (mechanical and electronic), and comprehensive aircraft frame instruments with over 20 specific valve and pump products (LUN 7707, LUN 7461, LUN 7460, LUN 7468, LUN 7465-7467, LUN 7340, LUN 7349, BP-DCA pumps, LUN 7464, FNG-12 filter, LUN 7322, LUN 2475). The Hydraulics division manufactures pumps, motors, and aggregates for industrial machinery. Supporting these divisions, Jihostroj operates internal Surface Treatment (galvanizing), Heat Treatment (SOLO 600, SOLO 300, SECO/WARVICK, EBNER furnaces), and Tool Shop capabilities. The company also provides corrosion testing services per ASTM B117 standard.
