The story of The Weir Group is a Scottish narrative of engineering DNA and industrial evolution, a journey that began in 1871 with two brothers, George and James Weir. Descendants of the poet Robert Burns, the brothers possessed a different kind of creative genius—one for mechanics. They founded the firm G & J Weir to produce ground-breaking pumping inventions, providing the mechanical heartbeats for the legendary steamships built in the world-famous Clyde shipyards.

    At the very heart of their identity is a legacy of adaptation. In 1886, they established a machine shop in Cathcart, Glasgow, planting the seeds for a global empire. But Weir was never content to stay in one lane. During the tumult of the early 20th century, they produced over 1,100 aircraft and engines for the Great War and, in 1932, developed the autogiro—establishing the principle of auto-rotation that allows helicopters to land safely to this day. By 1946, their influence was cemented with a listing on the London Stock Exchange.

    This is a story of strategic focus. For decades, Weir grew through global acquisitions like Warman International and SPM, expanding into Oil & Gas. However, the modern chapter of their narrative is defined by a bold pivot. Recognizing the changing needs of the planet, Weir divested its Oil & Gas and Flow Control divisions to become a focused mining technology leader. This transformation was headlined by the $1.3 billion acquisition of ESCO in 2018, affirming their status as a titan of the sector.

    This is a story of "Mining technology for a sustainable future." In 2024, Weir launched a refreshed brand reflecting a deep commitment to accelerating the transition to smart, efficient mining. This wasn't just a slogan; it was followed by the milestone acquisition of Micromine in 2025. This move signaled their intent to build a sector-leading digital optimization platform, proving that the company started by two steam engineers is now defining the digital frontier of resource extraction.

    Today, the story of The Weir Group is one of a 150-year-old innovator that remains as vital as ever. It is a promise that through end-to-end solutions, Weir is not just extracting resources, but helping the industry do so in a way that safeguards the future.
