Conveyor Doors

Designed and patented by Walz & Krenzer in the 1960’s, the conveyor belt watertight bulkhead door uses simple pneumatic and hydraulic operation, incorporating a unique rotating section between the upper trough belt and the return belt. This ensures generous vertical and side clearance, thereby eliminating belt and sealing gasket damage. Custom designed for each application, these doors assure watertight integrity for subdivision bulkheads.

Our design features automatically actuated, self-aligning plugs to accommodate belt drift and assures positive sealing. These doors, proven through decades of satisfactory service, are available for belt widths up to 120”.
