Commissioning procedure:
a) Filling the pump with lubricant
The pump units may be operated with clean oil or grease from original
packages only!
The initial filling with grease must be done through the filler nipple in order to
fill the pump’s suction chamber safely.
Hint:
For the pump’s initial filling with grease, we recommend to fill it with
transmission oil up to the stirring wing in order to ensure a speedy and
better bleeding.
When selecting the transmission oil, however, proper compatibility
with the lubricant used needs to be ensured.
b) Connecting lube lines
The lube point lines must be clean and free of any obstruction.
Connect the outlets of the pump elements or progressive distributors with the lube lines.
These lines must be clean and free of any obstruction. You may not connect the lube lines to
the lube points unless the lubricant comes out free of air. Check all connections of the lube
lines for tightness and the lube points for air-free lubricant release.
Note that the pump unit, depending on the ambient conditions, is capable of building up
maximum pressures of far more than 500 bar!
Warning!
If the pump unit is not already fitted with pressure control valves
on delivery, the lube lines need to be retrofitted with suitable
protective elements in order to prevent the pump unit and lube
lines from overloading.
Warning!
Any pump pressure above the admissible operating pressure
of 250 bar may result in the destruction of the system and
situations endangering health!
6.6 Shutdown
The unit is shut down when switched off and disconnected from the external power supply.
Work on electric facilities may only be performed by skilled electricians
in conformity with DIN VDE 1000-10.
