About Gustav Schmidt
Gustav Schmidt GmbH & Co. KG, headquartered in Wilnsdorf (Siegen-Wittgenstein district), has been active in technical trade and service for hydraulics, pneumatics and cleaning technology since 1919. The offering includes the assembly of hydraulic and industrial hose lines from single pieces to large-scale series of several tens of thousands of pieces per month, in-house production of power units, hydraulic cylinders, seals and pipe bends, as well as pipework and plant assembly including commissioning. This is complemented by engineering services (CAD/eCAD, 3D models, plant planning), pressure accumulator management with test and filling units up to 550 bar, hose and fluid management, and logistics solutions such as Kanban supply and mobile workshop containers. Via an online shop with around 120,000 articles, orders placed until 21:00 are shipped the same day. Core partners are Parker (over 60 years), STAUFF, Kaeser and Kärcher. Locations are in Wilnsdorf and Lutherstadt Wittenberg.
