Integreal Lubricator

The RMZ ECO Grease Injection Head consist of two major sub-assemblies, the Eco Stuffing box and Line Wiper and the flow tube assembly.
The hydraulic stuffing box is designed to pack-off on a stationary wireline by means of a pack-off rubber, the hydraulic line wiper will wipe excess grease from a moving wireline.
The concentric flow tube assembly is made up of an inner flow tube sized to fit tightly around the wireline and an outer sleeve to support the assembly. When entering a well under pressure, viscous grease is injected into the flow tubes at a pressure greater than the existing well pressure. The grease fills the annular space between the inner wall of the flow tube and the outside surface of the wireline, forming a liquid seal that contains the well fluids while allowing wireline movement.
