A seal for a rotating center valve vacuum filter drum has a non-flat cross section with an elastomeric core and a chemical resistant sheathing. The seal is installed under tension so that, as wear occurs during operation, positive sealing contact is maintained. The non-flat cross section provides a nesting relationship with the center valve slot and stationary shoe to resist any tendency to wander out of the slot.

Joint étanche pour le tambour d'un filtre rotatif à vide à vanne centrale. Il possède une section transversale qui n'est pas plane, un noyau en elastomère et un revêtement résistant aux agents chimiques. Le joint étanche est installé en tension de sorte que, au fur à mesure qu'il s'use pendant l'utilisation, un contact de scellement étanche est maintenu. La section transversale non plane assure l'emboîtement avec la fente de la vanne centrale et le sabot fixe pour empêcher le joint étanche de sortir de la fente.
