The present invention relates to a transportable system for delivering lubricant to a target, more specifically for lubricating machine parts and/or for re-filling a central or a de-central lubricating system. Further, the present invention relates to parts of the transportable system, the parts being a pressure releasing coupling, a gear pump and/or a high pressure pump.

A grease tool and method for greasing a wheel bearing where the grease tool includes a handle and manifold. The handle and manifold define a central passage that extends through the grease tool. A supply channel is formed radially between the central passage and an exterior surface of the grease tool and extends axially through the handle to an annular supply recess formed in the manifold. A grease fitting attached to the grease tool to facilitate a supply of grease through the supply channel and the supply recess to an inwardly facing surface of the wheel bearing. The central passage in the grease tool facilitating sliding the grease tool over an axle that extends through the wheel bearing and positioning of the grease tool within the wheel bearing evenly repacking of the bearing in a position over the axle.

A central lubricating station for lubricating one or more machine part(s), having a container base adapted for holding at least two replaceable containers. Each replaceable container holds at least one type of lubricant; and one or more pump(s) is configured for pumping at least one type of lubricant interchangeably from the at least two replaceable containers to the one or more machine part(s); and a motor is configured for driving the one or more pumps.

A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

A lube skid apparatus configured to be moveable and transportable. The lube skid having one or more tanks carried by a scaffold of the lube skid. One or both tanks having sloped bottom walls to optimize flow of fluids in the tanks to minimize residual fluid left in the tank. One or both tanks having sloped top walls configured to contain and direct the flow of fluid spills on the skid to an adjacent sump. The skid also carries a plurality of service devices such as a motor, an air compressor, a tank to hold compressed air, pumps to move fluid with associated filters and hoses, and one or more service storage drawers.
