It is listed for the SP1600, SP1600X, SP2600 and SP2600X.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the impeller does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe impeller is the part that actually moves the water. It spins on the motor shaft and throws water out to the volute, and everything downstream of it, filter, heater, returns, depends on the flow it makes. When the vanes wear, crack, or fill with sand and debris, flow drops even though the pump sounds normal and the basket is clean.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGet the rating right\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eImpellers are matched to motor horsepower, which is why Hayward sells several for the same pump body. This one is the 2.5 HP max rate, 2 HP full rate part. Check the rating on the motor label before ordering, because an impeller from a different size will run but will not deliver the curve the pump was built around.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you are in there\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReaching the impeller means pulling the seal plate, which disturbs the shaft seal. Fitting a fresh seal at the same time saves doing the same teardown again a month later.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634289684692,"sku":"HAY-101-4188","price":76.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_53000282-8e97-4561-a6b2-e86f32779c8f.png?v=1788828276","url":"https:\/\/www.activepoolsupply.com\/products\/impeller-2-5-hp-max-rate-2-hp-full-rate","provider":"Active Pool Supply","version":"1.0","type":"link"}
