Zusammenfassung:	The invention relates to a behind-pump sealing device. The behind-pump sealing device comprises a front-pump seal cover, a behind-pump seal seat, a first stationary ring, a movable ring unit mechanism, a second stationary ring and a behind-pump seal cover. The behind-pump sealing device penetrates through a pump main shaft and is mounted on the a behind-pump plate; the front-pump seal cover, the behind-pump seal seat and the behind-pump seal cover form a closed space; the first stationary ring is fixed in the front-pump seal cover, and the second stationary ring is fixed in the behind-pump seal cover; the movable ring unit mechanism is fixed on the pump main shaft, movable ring frictional faces are arranged at two ends of the movable ring unit mechanism, and the movable ring frictional faces separately compress the frictional faces of the first stationary ring and the second stationary ring. The pump main shaft drives the movable ring unit mechanism to rotate in the closed space, and the frictional faces of t
