{"product_id":"shaft-seal-5-8","title":"Pentair Mechanical Shaft Seal, 5\/8\"","description":"\u003cp\u003eThe Pentair 354545S is a Type 6 mechanical shaft seal set for a 5\/8 inch motor shaft. It is the genuine Pentair part, listed for the Challenger high flow and high pressure inground pumps and for the WaterFall specialty pump, and also listed for Pinnacle, SuperFlo, SuperMax, OptiFlo and Dynamo models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the seal does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe shaft seal is the barrier between wet end and motor. Two lapped faces run against each other, one spinning with the shaft and one held still in the seal plate, and the film of water between them is all that separates pool water from the motor bearings. When that pair wears, the first sign is a drip under the motor end of the pump, and the last sign is a seized motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMaterials and construction\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair specifies Buna and graphitic plastic for this seal. It cross references to the US Seal PS-200, so a shop quoting a PS-200 is quoting the same seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplace both halves\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is sold as a set for a reason. The two faces wear into each other, and fitting a new rotating half against an old ceramic seat will weep almost immediately. Change the pair, keep the faces clean and dry going in, and lubricate only the elastomer, never the lapped faces.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625748410580,"sku":"PAC-101-4545","price":35.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1287f3e8-0ca7-442f-9c38-36e6e6d1836e.jpg?v=1788691532","url":"https:\/\/www.activepoolsupply.com\/products\/shaft-seal-5-8","provider":"Active Pool Supply","version":"1.0","type":"link"}
