USSEALPACO91909832 PACO-91909832* Mechanical Seal Kit

Product Description

The USSEALPACO91909832 PACO-91909832* is a single mechanical seal kit designed for Grundfos and Paco centrifugal pumps. 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.

This 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.

Key Features

• Single mechanical seal construction using carbon, ceramic, and Buna-N materials
• Includes mechanical seal, gaskets, impeller cap screw, impeller washer, impeller key, and impeller nut
• Complete kit format supplies all necessary components for a full seal service
• Replaces obsolete part number K105-1

Compatibility

This kit replaces Grundfos/Paco part number K105-1. It is designed as an OEM-style replacement seal kit for Grundfos and Paco centrifugal pump models that originally used the K105-1 seal assembly.

Installation Notes

Installation should be performed by a qualified plumber or pump service technician. 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.
