● Type：mechanical seal for sodium pump, mechanical seal for lead-bismuth pump, mechanical seal for molten salt pump, mechanical seal for charging pump, mechanical seal for waste heat discharge pump, mechanical seal for high pressure safety injection pump, mechanical seal for medium pressure safety injection pump , Mechanical seal for safety injection/low pressure safety injection pump, nuclear three-stage CAP1400, AP1000 waste heat exhaust pump mechanical seal, equipment cooling water pump mechanical seal, boric acid transfer pump mechanical seal, fuel pool cooling pump mechanical seal, chilled water pump mechanical seal, chemical additives Mixing pump mechanical seal, important plant water pump mechanical seal
● Features：R&D and application cover a full range of nuclear secondary and tertiary pump mechanical seals for the second-generation plus, third-generation, and fourth-generation nuclear power units. The product prototype has undergone various appraisal tests (variable working conditions, durability, cold shock, thermal Impact, impurity, etc. tests), of which the mechanical seals for safety spray/low pressure safety injection pumps, medium pressure safety injection pumps and other pumps can meet the requirements of exceeding design basis accident tests (160℃, self-flushing) Among them, CAP1400, AP1000 waste heat exhaust pump mechanical seals can withstand 15.4MPa overpressure conditions. The mechanical seal of the important plant water pump can meet the power failure conditions of the whole plant, and its compact structure can replace the existing packing seal.
