It is molded in plastic to match the original housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the volute does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe volute is the front half of the pump casing. Water enters it, the impeller spins inside it, and the shaped passage turns that spin into the pressure that drives a pressure side cleaner. Because it is the part holding that pressure, it is also the part that shows a crack first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen it needs replacing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA booster pump that weeps at the front, or that loses pressure no matter how many seals go into it, usually has a failed housing. A hairline crack opens under load and closes again when the pump stops, which is what makes it hard to spot on a bench. Once the sealing face is damaged, no o-ring will make up the difference.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile it is apart\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe volute o-ring is a separate part and belongs in the same order. Check the drain plug and its washer at the same time, since both live in the same water path.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627588497620,"sku":"LET-201-2367","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7ba4b36d-a145-4a3a-811a-ee9cd0c3342d.png?v=1788723969","url":"https:\/\/www.activepoolsupply.com\/products\/volute-letro-new-style-booster-pump","provider":"Active Pool Supply","version":"1.0","type":"link"}
