Sie befestigt das Laufrad fest auf der Pumpenwelle, gew\u00e4hrleistet den korrekten Drehschluss und verhindert ein L\u00f6sen des Laufrads w\u00e4hrend des Betriebs. Der rechtzeitige Austausch einer verschlissenen oder besch\u00e4digten Laufradmutter stellt die volle Pumpenleistung wieder her und sch\u00fctzt die umliegenden Bauteile vor Verschlei\u00df.<\/p>\n<h3>Kompatibilit\u00e4t<\/h3>\n<p>Diese Laufradmutter ist ein Original-Ersatzteil f\u00fcr die Bosta STP-Gegenstrompumpenreihe. \u00dcberpr\u00fcfen Sie vor der Bestellung stets die Teileliste Ihres Systems (Position Nr. 20), da bei verschiedenen STP-Varianten oder Leistungsstufen m\u00f6glicherweise unterschiedliche Hardware-Versionen zum Einsatz kommen. Im Zweifelsfall kl\u00e4ren Sie die Modellnummer und das Typenschild Ihres Systems mit Ihrem Bosta-H\u00e4ndler ab.<\/p>\n<h3>Warum Echtheit z\u00e4hlt<\/h3>\n<p>Original-Ersatzteile von Bosta werden genau nach den f\u00fcr die STP-Pumpeninnenteile erforderlichen Toleranzen gefertigt. Eine falsch ausgew\u00e4hlte Mutter kann zu Unwucht des Laufrads, Vibrationen, vorzeitigem Lagerausfall oder Motorsch\u00e4den f\u00fchren \u2013 all dies sind Reparaturen, die weitaus kostspieliger sind als die Verwendung des richtigen OEM-Befestigungselements von Anfang an. Die direkte Beschaffung \u00fcber einen autorisierten Bosta-H\u00e4ndler garantiert die Echtheit und R\u00fcckverfolgbarkeit der Teile.<\/p>\n<h3>Installation<\/h3>\n<p>Der Austausch der Laufradmutter sollte bei vollst\u00e4ndig abgeschalteter und von der Stromversorgung getrennter Pumpe erfolgen. Der Zugang zu den inneren Bauteilen der Pumpe erfordert in der Regel die Demontage des Pumpengeh\u00e4uses; befolgen Sie die Angaben im STP-Wartungshandbuch hinsichtlich der Drehmomentwerte und der Reihenfolge beim Zusammenbau. Es wird dringend empfohlen, die Installation von einem qualifizierten Schwimmbadtechniker durchf\u00fchren zu lassen, um Sch\u00e4den am Laufrad oder am Gewinde der Welle zu vermeiden.<\/p>","protected":false},"excerpt":{"rendered":"<p>Bosta &#8211; Impeller Nut for Counter Current System Type STP (Item No. 20) This is the genuine Bosta replacement impeller nut (diagram position No. 20) designed specifically for the Bosta Counter Current System, type STP.
