It is the genuine part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow a peristaltic pump works\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThere is no impeller and no seal touching the chemical. A rotor squeezes a flexible tube against the pump head and pushes the liquid along inside it. That is what makes these pumps tolerant of aggressive chemistry, and it is also why the tube is the part that wears out.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it is a scheduled item\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tube is compressed and released thousands of times an hour. Eventually it takes a set, loses its recovery, and then splits. When that happens the pump keeps running and sounds completely normal while no chemical reaches the pool, which is the failure that costs people a week of bad water before anyone checks the feeder. Change the tube on a schedule instead of waiting for it.\u003c\/p\u003e","brand":"Rola-Chem","offers":[{"title":"Default Title","offer_id":48627842253012,"sku":"ROL-451-6084","price":21.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_24ac94ae-0c47-4eed-bdb9-46826dca0738.jpg?v=1788728117","url":"https:\/\/www.activepoolsupply.com\/products\/flex-tube-w-clamp-8","provider":"Active Pool Supply","version":"1.0","type":"link"}
