Commissioning
• Starting up the electric motor in tip operation.
• Check the direction of rotation.
•
Bleed the delivery pipe, e.g. via the measuring connection, until operating uid is
discharged free of bubbles. The required operating pressure may now be set, but
not before.
•
With a preloading valve of >1 bar, the system must be bled between the pump
and the preloading valve.
•
If the suction port is situated below and the oil level is below the pump, take
special care during the bleed process!
•
The system is only bled when there are no jarring noises and there is no foam
build-up in the tank.
• The pump can now be loaded with the operating pressure.
•
With a positive oil inlet, the pump must be bled via the bleeder screw in the end
cover. Opening the bleeder screw allows the air to be bled out of the pump (while
the pump is shut down).
•
The pump must not be operated with an opened bleeder screw. Operating the
pump while the bleeder screws are open will damage the pump.
NOTE
If these points are ignored, the pump could be damaged.
