GREASE PUMP GREASE PUMP
Pump element is drawing in :
(1) (1)
Desmodromic actuation of the pumping elements Desmodromic actuation of the pumping elements
The pumping elements are not driven by a simple return spring but have a desmodromic push-
pull actuation. This guarantees are reliable functioning of the pump even by the use of rigid
grease(up to NLGI 2) and very low ambient temperatures.

INTEGRATED ELECTRONICAL CONTROLLER INTEGRATED ELECTRONICAL CONTROLLER
When the central lubrication processor is time controlled, the cycle duration and the lubrication time
can be adjusted. Cycle duration means the period form the beginning of one lubrication process to
the beginning of another lubrication process.

Adjusting the parameters Adjusting the parameters
The lubrication time can be set by means of graduating switches in the controller's sight glass.
To adjust the time setting, remove the red frame on the pump's motor housing using a flat screw-
driver, loosen the four screws and remove the transparent protective cover.
The lubrication time can be adjusted using a flat screw driver. If the cover plate is not replaced
properly, water may enter the controller and damage it. In this case, the guarantee is no longer
valid.
