The Paul Pleiger Maschinenfabrik was founded in 1925 by Paul Pleiger in Sprockhövel, Germany. The company initially manufactured compressed air valves and fittings for the mining sector. A few years later, the company also started to manufacture pneumatic mining pumps. In 1937 the mechanical production was started in the newly acquired facility in Witten-Herbede.
In the 1950s, during the period of extensive economic growth in Germany, the company broadened its product range to include components for hydraulics like radial piston motors and actuators as well as control valves and eventually centrifugal pumps for wastewater. Simultaniously, the company started the production of plastics and was a pioneer as a processor of polyurethane cast elastomers. In the years that followed, divisions for electronic technology and laser optics were founded.
The development of new markets, the creation of new products and the overseas expansion led to significant growth. With three sites in Germany and production facilities in China, South Korea and the USA, the now strongly diversified company split its existing divisions into separate companies in 1996.
