They wear as a pair. Fitting a new face against an old one leaves the same leak, which is why this part supplies both halves.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater appearing at the joint between the pump body and the motor means the shaft seal has gone. It is worth acting quickly, because the water that gets past a failed seal runs directly at the motor bearings and takes the motor with it.\u003c\/p\u003e","brand":"Speck Pumps","offers":[{"title":"Default Title","offer_id":48627344507092,"sku":"SPK-101-2675","price":68.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d195dfa7-e176-4fdb-8fe7-39aa17454dc0.png?v=1788722688","url":"https:\/\/www.activepoolsupply.com\/products\/shaft-seal-complete","provider":"Active Pool Supply","version":"1.0","type":"link"}
