At FSI we believe that the proper selection and the expected performance of a mechanical seal rely heavily on accurate equipment dimensional information as well as detailed operating conditions. We work closely with our customers and distributors to ensure that this information is recorded using mechanical seal data sheets for documentation. The equipment type and service conditions are then used to determine the proper environmental controls and API piping plans. The mechanical seal technical information makes each FSI seal a customer, equipment, and service specific design. Any changes are reviewed and noted to assure all parties that the most reliable mechanical seal has been selected.
