DDRB-N Type Multi-Point Lubrication Pump (31.5 MPa)
I. Product Overview
The DDRB-N (formerly ZB) type multi-point lubrication pump is suitable for centralized lubrication systems in medium and small machinery and equipment with lower lubrication frequency, fewer than 50 lubrication points, and a nominal pressure of 31.5 MPa. It supplies lubricant directly or via a single-line distributor to each lubrication point. Particularly suited for single-machine equipment in metallurgy, mining, heavy machinery, port transportation, and construction.

Four: Dimensions

Section 4: Application Fields
The multi-point lubrication pump of this type should be installed in an environment with suitable temperatures, minimal dust, and easy access for inspection, maintenance, and replenishment.
2. Refueling the storage tank must be done using an oil pump through the refueling port of the tank. It is strictly forbidden to add unfiltered media by removing the cover.
3. Wire the motor according to the rotation direction indicated on the storage cylinder wall, and do not reverse.
4. The number of oil ports can be selected from 1 to 14 at will. Unnecessary components of the pressure oil plunger pump can be removed according to the equipment requirements, and the threaded holes can be sealed with M20x1.5 plugs.
5. Adjust the oil volume by adjusting the position of the screw shown in the illustration.

V. Operation Description
The DDRB-N type multi-point lubrication pump is mainly composed of an oil reservoir, a reduction mechanism, an oil-pressure plunger pump, and an electric motor.
The motor drives the worm and worm gear to reduce speed, with the worm gear shaft rotating the eccentric drive wheel at a low speed. The drive wheel's pull plate drives the plunger of the oil pump element to perform reciprocating suction and pressure oil movements, thereby expelling lubricant from the outlet of each pump element.
