The Sterling-Sterlco 692-98445-00 Mechanical Seal Kit is used to ensure that the fluid circulation is maintained around the pump shaft assemblies in HVAC systems. It operates by using precision gaskets to provide a tight seal between rotating and stationary parts of the pumps, such that when in operation, the shaft can rotate but not leak liquid out in boiler circulation and hydronic HVAC systems. It is installed in the pump housing where the sealing surfaces match on the shaft and internal pump chamber. This contact between the shafts can assist in keeping the fluid pressure within the system.
