Positionn\u00e9 dans la gorge autour du couvercle du panier de pr\u00e9filtration, il forme le joint \u00e9tanche \u00e0 la pression qui maintient la chambre de pr\u00e9filtration remplie d'eau et exempte d'air pendant le fonctionnement. Sans un joint intact \u00e0 cet endroit, la pompe perd son amor\u00e7age et le d\u00e9bit chute imm\u00e9diatement.<\/p>\n<h3>Le r\u00f4le de ce joint torique dans l'UltraFlow Plus<\/h3>\n<p>Le joint torique de couvercle est comprim\u00e9 entre le couvercle du panier de pr\u00e9filtration et le corps de la pompe, emp\u00eachant l'entr\u00e9e d'air et les fuites d'eau au point que vous ouvrez \u00e0 chaque nettoyage du panier. Chaque d\u00e9montage et remontage soumet le caoutchouc \u00e0 un cycle de compression et de rel\u00e2chement. Avec le temps, le mat\u00e9riau s'aplatit, durcit ou se fissure l\u00e9g\u00e8rement, et l'\u00e9tanch\u00e9it\u00e9 est compromise. Le remplacement de ce joint torique r\u00e9tablit une chambre de pr\u00e9filtration enti\u00e8rement sous pression et un d\u00e9bit constant vers le rotor.<\/p>\n<h3>Avec quels mod\u00e8les UltraFlow Plus est-il compatible ?<\/h3>\n<p>La r\u00e9f\u00e9rence R39300600 est le joint torique de couvercle pour la famille de pompes Pentair UltraFlow Plus. Les r\u00e9f\u00e9rences crois\u00e9es incluent les anciennes plateformes Ultra-Flow et Ultra-Flo fabriqu\u00e9es apr\u00e8s novembre 1994, et elle est \u00e9galement cit\u00e9e comme compatible avec les vannes multivoies \u00e0 collier Pentair et les couvercles de filtre \u00e0 montage sup\u00e9rieur Meteor. Confirmez le num\u00e9ro de mod\u00e8le de votre pompe avant de commander si vous n'\u00eates pas s\u00fbr de la g\u00e9n\u00e9ration que vous poss\u00e9dez.<\/p>\n<h3>Signes indiquant qu'il faut le remplacer<\/h3>\n<p>Le sympt\u00f4me le plus \u00e9vident est un goutte-\u00e0-goutte lent ou un suintement constant autour du joint du couvercle du panier de pr\u00e9filtration lorsque la pompe fonctionne sous pression. Vous pouvez \u00e9galement constater que la pompe a du mal \u00e0 maintenir son amor\u00e7age \u2014 des bulles d'air visibles \u00e0 travers un couvercle transparent, ou la pompe n\u00e9cessitant un r\u00e9amor\u00e7age r\u00e9p\u00e9t\u00e9 apr\u00e8s le nettoyage du panier. Un joint torique de couvercle qui semble cassant, aplati ou pr\u00e9sente des fissures en surface doit \u00eatre remplac\u00e9 imm\u00e9diatement, et non lubrifi\u00e9 puis remis en place.<\/p>\n<h3>Comment l'installer<\/h3>\n<p>Arr\u00eatez la pompe et rel\u00e2chez la pression du syst\u00e8me avant d'ouvrir le couvercle. Retirez l'ancien joint torique, nettoyez la gorge de tout d\u00e9bris ou caoutchouc d\u00e9grad\u00e9, et positionnez le nouveau joint torique uniform\u00e9ment sur toute la circonf\u00e9rence sans le vriller. Appliquez un film fin de lubrifiant \u00e0 base de PTFE ou de silicone sur le joint torique avant de refermer le couvercle \u2014 n'utilisez jamais de graisse \u00e0 base de p\u00e9trole, qui d\u00e9grade le compos\u00e9 de caoutchouc. Remettez le couvercle en place et serrez-le \u00e0 la main ; aucun outil n'est n\u00e9cessaire.<\/p>","protected":false},"excerpt":{"rendered":"<p>Pentair UltraFlow Plus prefilter lid O-ring This is the genuine Pentair O-ring that seals the prefilter (strainer) lid on the UltraFlow Plus pump.
