Based in Crewkerne, Somerset, UK and following in the tradition of Trist; Bestobell and Sterling Mechanical Seals; S M Seals specialise in the design, test, manufacture and supply of an extensive range of mechanical sealing solutions for the Power Generation Industry.
Design of the reversible pump turbine seal began in the late 1960's whilst working in close co-operation with our client, this resulted in the first installation and commissioning of this type of seal at the Cruachan Pump Storage Scheme, Scotland in 1970. This development was a natural progression from many years experience, dating from 1953, in designing and supplying seals for main Cooling Water Pumps in Fossil and Nuclear fuelled power stations. Its success heralded the start of a new era for our range of Water Turbine Main Shaft Seals for the Hydropower Industry.
Following on from testing and development at Cruachan, came a contract award for Dinorwig - the largest pump storage station in the UK. Working in partnership with their engineers and through detailed in-house tests and field trials; we have been able to advance considerably the reliability and materials of construction for our seals
Our design centre uses the latest design software, which includes 3D and Finite Element Analysis (FEA) modelling. All seals are 3D modelled to ensure compatibility and FEA conducted on critical components to ensure structural integrity.
Furthermore, we have an in-house Research and Development lab with which we can simulate our customers operating parameters on our unique scale model test rig, from which we gather and analyze critical data.
Refinement of our seals is a continuous program and our test rig data acquisition and signal-processing equipment used in conjunction with design office software allows us to achieve our aims.
