Established in 1925 by Paul Pleiger, this Witten‑based engineering firm began by producing compressed‑air valves and mining fittings, and not long after introduced pneumatic mining pumps. By the 1950s, they had broadened their scope with hydraulic components such as radial‑piston motors, swivel drives, control valves, and centrifugal wastewater pumps. Simultaneously they ventured into plastics—initially cast elastomers and later thermoplastics—and expanded further into electrotechnology and laser optics. In the late 1990s, restructuring led to the formation of Pleiger Maschinenbau as a standalone entity, embarking on international growth with additional sites in Germany and production units in the United States, China, and Korea.
Today, the company is recognized as a global leader in electro‑hydraulic shipboard systems, hydraulic drives, wastewater centrifugal pumps, coke‑oven valves, and cast components crafted from light and non‑ferrous metals. Their core strength lies in offering end‑to‑end solutions—from project design and engineering through full production and commissioning—ensuring efficiency and coherence for clients. They have earned the trust of major industrial entities and esteemed shipyards worldwide, with equipment installed on over 7,000 vessels.
The firm’s head office and main production facility are situated in Witten, in Germany’s Ruhr area, benefiting from regional infrastructure and tradition. Its identity merges the innovation expected of German high‑tech manufacturers with the grounded values of a family‑owned enterprise. Embracing stability, sustainability, and continuous growth, the company also houses an in‑house development centre and partners with its own training organisation, shaping skilled professionals for the long term.
