description The utility model relates to a pressure sealing device, which is installed on the main pump plunger of a tri-jar plunger pump, mainly comprises a suction main, a suction valve, a spherical hinge sealing box, a hydraulic pump, and an offtake main, etc. The utility model is characterized in: the spherical hinge sealing box and the hydraulic pump are respectively installed on the pump head of the main pump, and forming a seal cavity, which keeps the differential pressures between the main pump and the seal cavity in certain scope. And since the pressure in the seal cavity is larger than it in the main pump cavity, the compression seal is achieved, which ensures that the wearing part is free from etching by the slurry, therefore, the life length of the seal components is enhanced.
