It provides all the components needed to restore proper shaft sealing in pump service applications. The kit is constructed with carbon, ceramic, and Buna-N materials, which are standard for mechanical seal assemblies in hydronic and water-circulation systems. Licensed plumbers, pump mechanics, and HVAC service technicians typically install this kit during scheduled maintenance or when addressing seal failure and leakage.\u003c\/p\u003e\n\u003cp\u003eThis seal kit is used in residential and light commercial pump service work where Grundfos or Paco centrifugal pumps require seal replacement. It is suited for applications involving hydronic heating, cooling circulation, and general water transfer systems. The complete kit eliminates the need to source individual components separately, reducing downtime during service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle mechanical seal construction using carbon, ceramic, and Buna-N materials\u003c\/li\u003e\n  \u003cli\u003eIncludes mechanical seal, gaskets, impeller cap screw, impeller washer, impeller key, and impeller nut\u003c\/li\u003e\n  \u003cli\u003eComplete kit format supplies all necessary components for a full seal service\u003c\/li\u003e\n  \u003cli\u003eReplaces obsolete part number K105-1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis kit replaces Grundfos\/Paco part number K105-1.

Before beginning work, shut off power to the pump at the disconnect and close isolation valves to relieve system pressure and drain the volute. Handle seal faces carefully to avoid contamination or chipping of the ceramic and carbon components, as damaged faces will result in immediate leakage. Follow the pump manufacturer's service documentation for proper impeller torque sequence and reassembly procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Style\u003c\/strong\u003e: Single Mechanical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction Materials\u003c\/strong\u003e: Carbon, Ceramic, Buna-N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Contents\u003c\/strong\u003e: Mechanical Seal, Gaskets, Impeller Cap Screw, Impeller Washer, Impeller Key, Impeller Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReplaces\u003c\/strong\u003e: K105-1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: USSEALPACO91909832\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PACO-91909832*\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"US SEAL","offers":[{"title":"Default Title","offer_id":51523415474482,"sku":"PACO-91909832*","price":666.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3466fddca737818c29ab5115728913c3.jpg?v=1785442081","url":"https:\/\/voomisupply.com\/products\/ussealpaco91909832-paco-91909832-mechanical-seal-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
