The triple-sealed motor and run-dry protection are the standout durability features — worth highlighting for customers who’ve had cheaper macerators fail from dry running or corrosion. The ignition-protection rating is important if the pump is going near the engine compartment or a fuel tank; confirm this with the customer before recommending a non-rated alternative. Inlet accepts both 1½\" hose barb and 1½\" NPT, which gives flexibility on the plumbing connection.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199433048100,"sku":"6-185902094","price":514.29,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/6-185902092_1ac6da4c-8dcf-45e2-a4fe-543b3a07ef4b.jpg?v=1785605273","url":"https:\/\/marisolmarine.com\/products\/jabsco-18590-2094-24v-self-priming-12-gpm-macerator-pump-6-185902094","provider":"Marisol Marine Company","version":"1.0","type":"link"}
