The pump unit is to be filled with grease the very first time through the filling
nipple in order to ensure that the suction chamber of the pump is kept free of
air bubbles.
Recommendation: Alternatively, fill the pump the very first time with gear oil
up to the agitator blade to provide for faster and better
ventilation. While doing so, however, select such kind of
gear oil, which is compatible with the lubricant to be filled.
Danger of injury when reaching with your hands into container with the pump
unit running. Before reaching, separate the pump unit from the power supply.
b) Venting of the pump unit
Venting on the pump element
For that purpose, switch-on the pump unit with the lubricant feeding lines not installed as
many times as necessary to have the lubricant emerging at the outlet without air bubbles.
c) Connecting the lubricant feeding lines
Make sure that the lines feeding the lubricating point have been cleaned and
enable free flow!
Link the outlets of the pump elements to the lubricant feeding lines. These lines must be
clean and enable free flow. Connect the lubricant feeding lines to the points to be fed only,
when the lubricant emerges from the respective line without air bubbles. Inspect every
connector of the lubricant feeding lines for tightness and lubricating points for free lubricant
supply.
Beware that the pump unit can build up a maximum pressure of far beyond 500 bar
depending on the ambient conditions!
Warning!
If the pump unit has not yet been equipped with pressure relieving
valves at the date of shipment, the lubricant feeding lines are to
be completed with suitable protective elements in order to avoid
overload of both the pump and lubricant feeding lines.
Warning!
Pump pressure above the admissible operating pressure of 350
bar may lead to destruction of the installation and health-
hazardous situations!
