 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.

. 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.
