{"product_id":"pentairwaterpoolandspainc_la05lz","title":"Pentair Booster Pump Impeller — New Style | Letro Booster Pool and Spa Pump | LA05LZ","description":"\u003cp\u003eThe Pentair LA05LZ is the OEM replacement impeller for the Letro Booster Pool and Spa Pump (LA01N and EC-LA01N) — new style configuration. If your booster pump is losing pressure or failing to drive your pressure-side pool cleaner effectively, a worn or damaged impeller is a common cause. This is the correct OEM replacement for new-style units.\u003c\/p\u003e\n\u003cp style=\"background-color: #fff3cd; border: 2px solid #FFEAA7; padding: 15px; border-radius: 5px; margin: 15px 0; color: #856404;\"\u003e\u003cstrong\u003eIMPORTANT: CONFIRM YOUR PUMP STYLE BEFORE ORDERING\u003c\/strong\u003e\u003cbr\u003eThis impeller fits the new-style Letro Booster Pump — units manufactured after 1996. Earlier Letro booster pumps use a different impeller. The old-style and new-style impellers are not interchangeable. Verify the part number on your existing impeller or confirm your pump's manufacture date before ordering.\u003c\/p\u003e\n\u003cp\u003eThe impeller is the rotating component inside the pump that generates flow and pressure. Replacing a degraded impeller restores the pump's ability to deliver the flow rate your pressure-side cleaner requires to operate correctly.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eLA05LZ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eAlso Known As \/ Legacy Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eLA05L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eBooster Pump Impeller — New Style\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eMatch the part number on your existing impeller to LA05LZ before ordering — the old-style and new-style impellers are not interchangeable. When the pump is open for impeller replacement, inspect the shaft seal and any O-rings at the same time; replacing worn seals during the same service call avoids a repeat teardown.\u003c\/p\u003e\n\u003c!-- wft:processed:manual:2026-04-16 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53956255547667,"sku":"LA05LZ","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-booster-pump-impeller-new-style-letro-booster-pool-and-spa-pump-la05lz-2.webp?v=1776364902","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_la05lz","provider":"Poolaroo","version":"1.0","type":"link"}
