Type DDRB-N (originally ZB) multi-point lubricating pump applies to the multi-line centralized lubricating system of small and medium-sized machinery equipment with relatively lower lubricating frequency, the number of lubricating points under 50 and PN of 31.5Mpa. It is a grease delivery and supply unit that supplies and delivers lubricating grease to each lubricating point directly or through a single line distributor. It is especially suitable for such single equipment as for metallurgy, mines, ports, transportation, architecture and so on.

Use grease with minimum cone penetration 265(25℃,150g) 1/10mm or lubricating oil with minimum viscosity grade N68. Working environment temperature is -20~80℃.


Working principle

Type DDRB-N (originally ZB) multi-point lubricating pump is mainly composed of grease conservator, speed reduction mechanism, grease pressing plunger pump and motor, etc.

The motor drives worm; the turbine rotates at a reduced speed; the turbine shaft drives eccentric driving wheel to rotate at a low speed; the pulling plate of driving wheel drives the component of grease pressing plunger pump- plunger to do round act of absorbing and pressing grease, thus grease is discharged at the grease outlets of each pump component.


Use instruction

1.      This type of multi-point lubricating pump should be installed in the place with appropriate environmental temperature and less dust for the convenience of inspecting, grease supplementing and repair & maintenance.

2.      Grease must be supplemented into the grease conservator from the grease feeding mouth of the grease conservator by a feeding pump. Opening the cover to fill unfiltered working media is strictly forbidden.

3.      Connect the motor in accordance with the rotation direction specified on the rotation direction plate on the wall of grease conservator barrel. Reversal is forbidden.

4.      The number of grease feeding mouths can be selected arbitrarily within the range of 1 to 14. The component of grease pressing plunger pump can be dismantled voluntarily based on different requirements of equipment. Screw holes can be plugged with M20X1.5 screw plug.

5.      The adjustment of grease supply volume can be achieved by adjusting the location of Sequence 3 screw sleeve according to the diagram below.
