A dynamic seal advantageously utilizes a groove on the active side or surface of the seal to capture a leaked lubricant and hydrodynamically pump the lubricant back into the lubricated side of the seal. The groove stops short of the leading edge of the seal that faces the lubricant side thereby forming a static dam between the termination point of the groove and the seal edge. When the fluid pressure within the groove adjacent the static dam exceeds the opening pressure for the seal lip, the lubricant within the groove is pumped back into the lubricant side of the seal. The groove can have an induction zone wherein the fluid pressure rise is gradual and a booster zone wherein the fluid pressure rise is relatively faster than in the induction zone. The booster zone is disposed adjacent the static dam.
