The Weir Group plc is an engineering company headquartered in Glasgow, Scotland. It is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index. The company operates in over 70 countries employing approximately 14,000 people focused on mining, oil and gas and power markets.
The Company was established in 1871 as an engineering firm by two brothers, George and James Weir, founding G. & J. Weir Ltd. The Weir brothers produced numerous groundbreaking inventions in pumping equipment, primarily for the Clyde shipyards and the steam ships built there. These pumps became extremely well known for their use as boiler feedwater pumps, and for ship's auxiliary equipment such as evaporators.
Under W G Weir, the company turned to producing munitions and war materiel in the First World War. As well as shells, they manufactured aircraft including the Royal Aircraft Factory F.E.2 fighter and bomber.
James George Weir (aviator, son of James Galloway Weir) a director of the company formed the Cierva Autogiro Company. G & J Weir would be a financial supporter of the company for several years. In 1943, they provided the finances for the construction of the W.9, an experimental helicopter, to Air Ministry requirements.
It was first listed on the London Stock Exchange in 1946. Double-acting Weir steam pumps were virtually standard fitment on British-built steamships, being used for pumping water, fuel, air and much else well into the 1950s, as well as being used on other ships worldwide.
21st century 
In recent years, the company has undergone significant reorganisation both operationally and in terms of its geographic footprint.
In July 2005, Weir sold its desalination and water treatment businesses, (Weir Westgarth, Weir Entropie and Weir Envig) to Veolia Water Systems, part of the water division of Veolia Environnement: Weir Westgarth had been a pioneer of the multi-stage flash distillation process used predominately to produce desalinated water from seawater.
