Functional description of the BEKA-MAX grease central lubrication system
The BEKA-MAX grease central lubrication system is a progressive system. Progressive means
that all lubrication points included in the central lubricating system are lubricated one after the
other. Lubricating the lubrication points one after the other makes it very easy to monitor a
progressive central lubrication system with an excess pressure valve. If a lubrication point does
not take any grease from the distributor, the progressive distributor is blocked and a pressure of
280 bar /4060 PSI builds up in the central lubrication system. Grease emerging on the excess
pressure valve of the pump element indicates a blockage.

Layout of the BEKA-MAX grease central lubrication system
An electrically driven EP-1 plunger pump pumps lubricant to the main progressive distributor.
The task of this element is to distribute grease to the sub-progressive distributors at the correct
ratio. The sub-progressive distributors then pump the grease to the individual lubrication points.

Description of the control unit
Lubricating and pause times are regulated by the control unit in the driver's cab of the tractor
(refer to chapter Info-Center “Menu 1-5 central lubrication”).
