REBS block distributor type VK and VM

Progressive distributors are devices for distributing lubricant whose pistons are controlled hydraulicailyin sequence by the compressed lubricant in such a way that the lubricant is forced out of the individualorifices one after the other in succession (i. e. progressively).

Obstructions in the flow of lubricant within the distributor and in the network of lubricant pipes (e.g.distributor orifices blocked by unremoved setscrews, compressed pipes, blocked lubricant bores or contamination of the lubricant itself) cause the distributor to malfunction.

With manual pumps, the obstruction is apparent through the counterpressure which builds up and isvirtually impossible to overcome. With automatic pumps, the lubricant is ejected forcefully at thepressurerelief valve or activates an electrical overpressure switch for an alarm signal.

When installing the distributor, it must be ensured that it is mounted directly on machined surfaces only.If not, plain washers must be inserted between the distributor and the mounting surface.

When charging lubrication equipment, the distributor should, if possible, bevented with the pump inoperation to ensure accurate dosage of the lubricant. In view of their differing lengths, the lubricantpipes should, if possible, be charged before connecting them to the distributor.

It is extremely important that only high-quality clean lubricants are used. This especially important withgreases, where only ductile, non-bleeding and well-filtered greases should be used.

Distributor orifices which are not required can be closed. However, in this case it must be ensured thatthe lubricant can escape from another orifice, otherwise the distributor will block.

Side orifices can be joined by means of a bridge (fig. A).

Orifices lying opposite one another can be joined to form one single orifice by removing the machinescrew (1) in the passage connecting the orifices. The screw plug (2) can then be screwed into position(fig. B).

Two orifices positioned opposite one another should never be closed, as the lubricant can no longerescape!

Long distributors with multiple orifices should be vented to increase the accuracy of the grease dosage.To vent the distributor, switch the pump on and loosen the stop bolt of the first pisten (seen from the inlet)until lubricant which is free of air bubbles emerges.

bridging and plugging VK and VM

he block type of REBS Progressive Distributor is available in types: Vk and Vm.

The smallest distributor with 6 outlets can be reduced to 2 outlets by fitting bridge elements.

Depending on the type, these distributors are supplied with only one size of piston and with from 6 outlets upwards in steps of 2 outlets.

The upper limit of outlets is 32 for type Vk and 24 for Type Vm in any one block.

Starting from the feed line of a distributor, the outlet locations are designated R"for right and L" for left hand.

The number sequence that then follows gives the values of the outlets (the relationship ofthe smallest to the largest delivery per outlet). Each individual outlet has the value 1.

This evaluation gives: the number of outlets = number of connections (Example Vk 12-8/6).

In a connected distributor, several outlets are connected together to a single connection.


Opposite connections can be joined by removing the separating screw(to double the volume).
This screw should be removed before fitting the closing capscrew.

Adjacent outlets can be joined by bridge elements.
