I. Overview

The DDRB-N type multi-point lubrication pump is a feeding device for delivering grease to various lubrication points in centralized lubrication systems for medium and small-sized machinery and equipment with low lubrication frequency, less than 50 lubrication points, and nominal pressure of 31.5MPa. It can supply grease directly or through a single-line distributor. Particularly suitable for single-machine equipment in metallurgy, mining, heavy machinery, port transportation, and construction.

The multi-point lubrication pump of this type should be installed in an environment with suitable temperature, minimal dust, and easy access for inspection, maintenance, and replenishment.
2. Refueling the reservoir requires using a fuel pump to add oil through the reservoir's filling port. It is strictly prohibited to add unfiltered media by opening the cover.
3. Wire the motor according to the direction indicated on the storage cylinder wall, and do not reverse the direction.
4. The number of oil ports can be freely selected within the range of 1 to 14. Unnecessary components of the pressure oil plunger pump according to the equipment requirements can be removed, and the threaded holes can be sealed with M20x1.5 plug screws.
5. Adjust the oil quantity by moving the position of the screw in figure 3.
