摘要： An anti-rotation wiper ring for mounting in a pump equipment gland concentrically to the equipment pump rod, the ring having a wiper lip for preventing debris from being carried on the rod retracting within the equipment. Structure prevents the ring from rotating inwardly toward the rod and possibly outwardly thereafter out of the pump. In one embodiment, the wiper ring flange is held in the gland receiver groove via an anti-rotation anchor on the flange bottom surface mating with a gland locking groove on the bottom surface of the gland receiver groove. Alternatively or additionally, a stabilizer device is formed on the ring ID and prevents the ring's inward rotation. The stabilizer has standoffs to allow the passing rod to glide by while a recession above the standoffs reduces drag. Reliefs between the standoffs harmlessly pass any pressure which may escape the pump piston seal. A static seal keeps a potential leakage path closed in between the wiper ring OD and gland receiver groove ID.
