Travel No-Loc Valve The Harbison-Fischer Travel No-Loc Valve is an adaptation of the Harbison-Fischer Loc-No® Plunger concept to a Traveling Barrel Pump design. This device gives the Traveling Barrel Pump an opportunity to work without gas locking while retaining all of the advantages of a common Traveling Barrel Pump. The seal faces on the Travel No-Loc Valve are hard stellite inlaid to prevent wear and corrosion. |
