DRIVE
November 23, 2022
A hydrostatic seal assembly (60) includes a primary seal (68) configured to maintain a selected gap (76) between the primary seal (68) and a rotating component (64). The primary seal (68) includes a seal support (104), a seal shoe (72), and one or more seal beams (74) operably connecting the seal support (104) to the seal shoe (74). The one or more seal beams (74) are configured as spring elements integral with the seal shoe (72) to allow radial movement of the seal shoe (72) relative to the seal support (104). A seal carrier (66) including a radial outer wall (110) is configured to radially position the primary seal (68). The seal carrier (66) is configured for a non-contact relationship with the seal shoe (72) during operation of the hydrostatic seal assembly (68).
