A packaging type mechanical sealing device comprises a fixed ring and a compensating ring. The fixed ring is of a ring structure and is fixed on a gland, sealing filler is embedded on one side end face of the fixed ring, a compensating ring insert is fixed at one end of the compensating ring. Capacity-absorbed sealing filler is used as a friction material on the fixed ring, and the fixed ring and the compensating ring insert form a friction pair. Usage range of mechanical sealing is enlarged, running resistance of a water pump is reduced, sealing effect of the water pump is improved, energy saving and emission reduction are realized, and requirements for mounting technical ability of operators are reduced. Since the friction material of the fixed ring and the fixed ring are made integrally, a floating structure between a conventional friction material of the fixed ring and the fixed ring is changed, the structure of the fixed ring is simplified, the capacity-absorbed sealing filler on the fixed ring can be co
