The DPG Pneumatic Lubricator is an air-operated reciprocating lubricator that discharges a fixedamount of lubricant into systems during a lubrication cycle. It includes a transparent reservoir with low level and spring loaded follower, reversing valve, grease/oil strainer, FRL, air solenoid valve and a filler fitting for refilling of reservoir.
As compressed air is introduced into the lubricator, the piston moves forward, forcing lubricant outof the lubricator. The air valve is then automatically triggered, causing the piston to change directionand move to its original position. The system is now ready for lubricant to be sucked into the cavity. Compressed air is introduced to the system again and the cycle repeats itself.
