Buck Systems, a division of GEA Pharma Systems, was founded in 1990 as Gallay Systems Ltd. The Birmingham-based company was initially established to meet the specific needs of the Pharmaceutical market.

Since then, it has expanded its customer base considerably and now supplies and supports contained materials handling systems all over the world. As a part of its continued success, the company has developed and introduced new products and services based on IBC Systems for; Blending, Washing, Discharge and Dosing, Dispensing and Post Hoists. Today, Buck Systems remains customer focused and customer driven, and is now clearly established as the market leader in its field of materials handling, containment and technology.

1997 marked the introduction of the Buck® split valve into the pharmaceutical plant, which revolutionised containment in the production process. Since then, developing the containment technology and its applications further, together with GEA Niro (Buck Valve), has enabled Buck Systems to turn what was a high potency production area into a much safer environment for operators and a more efficient process facility for customers.

Since joining GEA and GEA Pharma Systems (GPS), a more common approach has also been developed between the GPS companies namely Aeromatic-Fielder, Buck, Collette, Courtoy, and Niro, to provide standardised interfaces enabling simple integration between technologies and equipment. This has resulted in the creation of the only effective single source supply for Solid Dosage Form facilities in the industry. This ability and expertise provides the 'Security of Outcome' the market aims to achieve.

To mark these achievements and to recognise the synergy between Buck Valve and Gallay Systems, in May 2003 Gallay Systems Ltd changed its name to Buck Systems. This strategic move will further develop and promote containment as a 'standard' in the pharmaceutical and healthcare industries.
