It is the genuine Pentair part, also listed as 35-5315.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch the pump first\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eChallenger impellers are horsepower specific and are also split between the high pressure and high flow builds. Read the motor label and the model on the pump before ordering, because an impeller from the wrong rating will bolt on and then perform nothing like the pump was designed to.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a worn impeller looks like\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWeak return jets, a filter pressure gauge sitting lower than usual and a pump that sounds normal while moving very little water. Pull the impeller and look at the vanes: erosion, cracks or debris packed into the eye all cost flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you are in there\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe mechanical seal is directly behind the impeller, so replacing it during the same teardown saves opening the pump twice. The impeller locking screw is a separate part and is worth renewing rather than reusing.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625710432468,"sku":"PAC-101-3128","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_a0d5e4cb-b903-4668-8d40-adc5ab2e8314.gif?v=1788688874","url":"https:\/\/www.activepoolsupply.com\/products\/impeller-1-1-2hp-full-rated-2hp-up-rated-high-pressure","provider":"Active Pool Supply","version":"1.0","type":"link"}
