The invention relates to a mechanical sealing ring for automatic two-way pumping. In the mechanical sealing ring for automatic two-way pumping, grooves are arranged at the middle of the sealing end faces and adjacent to the sealed high pressure fluid zone (the outer diameter position or the inner diameter position), the shape of the grooves is arc or elliptical arc or curve arc or linear in central symmetry. By using the sealing ring, mechanical sealing structure is simplified, the friction and abrasion degree due to direct contact between the sealing end faces of the mechanical sealing ring are reduced, abrasive grain abrasion due to suction of solid grains to the sealing end faces is avoided, the service life of the sealing piece is prolonged, the cost of the sealing device is reduced, and the invention can rotates in two ways.
