{"product_id":"impeller-3hp-high-flow","title":"Pentair Impeller 3HP, High Flow","description":"\u003cp\u003eThe Pentair 355068Z is the high flow impeller listed at 3HP, and is also cataloged under the number 355068. It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment, and a number worth checking\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe source lists it for the AF-120 and AFP-120 Waterfall specialty pumps and for the 3F 50 hz and 5F 60 hz Challenger high flow inground pumps, where those Challenger models are described as 5 hp. The impeller itself is designated 3HP. Both figures come from the manufacturer listing, so read the marking on the impeller you are replacing rather than going by the pump label alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHigh flow, not hi head\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eChallenger pumps come in high flow and hi head versions, and they use different impellers. High flow moves more water at lower pressure, which is what a waterfall or a big return circuit wants. Fitting the wrong profile changes the whole hydraulic picture, and in the wrong direction it will overload the motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you are in there\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePulling an impeller means unseating the mechanical seal behind it. It is normal practice to fit a new seal on reassembly rather than putting a disturbed one back, since a seal that leaks takes the motor with it.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48629289386196,"sku":"PAC-101-3183","price":56.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1fa51a24-a256-403e-b6d5-fb7ced86dad5.gif?v=1788761985","url":"https:\/\/www.activepoolsupply.com\/products\/impeller-3hp-high-flow","provider":"Active Pool Supply","version":"1.0","type":"link"}
