DDRB-N Multi-point Lubrication Pump - 4/2ZB2-M16F

DDRB-N Type Multi-point Lubrication Pump (31.5 MPa)

I. Product Overview

The DDRB-N (formerly ZB) multi-point lubrication pump is suitable for centralized lubrication systems of medium and small-sized machinery and equipment with low lubrication frequency, fewer than 50 lubrication points, and a nominal pressure of 31.5 MPa. It supplies lubricant directly or through a single-line distributor to each lubrication point. Particularly suitable for single-machine equipment in metallurgy, mining, heavy machinery, port transportation, and construction.

Section 4: Application Fields

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 must be done using an oil pump 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 rotation direction indicated on the storage cylinder wall, and do not reverse the direction.

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 screw holes can be sealed with M20x1.5 plug nuts.

5. Adjust the oil volume by adjusting the position of the nut shown in the illustration.

V. Action 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.

An electric motor drives the worm and worm gear to reduce speed, with the worm gear shaft rotating the eccentric drive wheel at a low speed. This, in turn, drives the plunger of the pressure oil plunger pump element to reciprocate, drawing and pressing oil. Consequently, the lubricant is expelled from the outlet of each pump element.
