DX Series — Piston Distributor (Prelubrication)

DX-SERIES OPERATION
1. Before the lubricant is fed to prelubrication distributor. (First installation)
2. The pressure built up in the centralized lubrication system pushes the collar upward
3. The lubricant fed to the distributor causes the metering piston to move toward the outlet.
4. When the pump is switched off, the pressure is relieved and the lubricant under preload below the metering pushes chamber the collar back toward the main line. In this process, spring tension causes the metering piston to return to its normal position. At the same time, the lubricant is möved from the metering chamber into the spring chamber. The prelubrication distributor is ready for the next lubrication cycle.
5. When the pump is switched on, the pressure built up in thecentralized lubrication system causes the metering piston to movetoward the outlet, expelling the lubricant that is under preloaded below the metering piston.
6. When the pumps is switched off, the pressure is relieved and the lubricant under preload below the metering chamber pushes the collar back toward the main line. In this process, spring tension causes the metering piston to return to its normal position.
At the same time, the lubricant is the metering chamber into the spring chamber.
