The SKA881 Lubricator is an air-operated pneumatic reciprocating lubricator that discharges a fixed amount of lubricant into systems during a lubrication cycle. It includes a transparent reservoir, spring loaded follower grease models, vent valve assembly and a filler fitting for refilling of grease reservoir. Oil Models have a flip cap.
As compressed air is introduced into the lubricator, the piston moves forward, forcing lubricant out of the lubricator. The air valve is then automatically triggered, causing the piston to change direction and move to its original position. The system is now ready for lubricant to be drawn into the cavity. Compressed air is introduced to the system again and the cycle repeats itself.
