10.3 Filling / bleeding the pump
Before initial start-up, the pump should be filled with pressure fluid and bled.
Pump installation below the fluid level:
1. Open the shutoff valves in the suction piping.
2. Open the bleeder screws on the end cover. If connected to a pump from a
different manufacturer, open the bleeder screw on the intermediate housing.
3. Close the bleeder screw again as soon as oil is discharged.
Pump installation above the fluid level:
1. If the suction piping connection is bove or to the side, fill the pump with oil
through this opening as much as possible.
The pump must be able to start up in a depressurized state, i.e. without back
pressure. If any resistance, for example a check valve, with a charging pressure
of >1 bar is included in the delivery pipe, the pipe must be bled between the pump
pressure connection and this resistance. A measuring connection or a suitable bleed
valve can be used.
During the first commissioning, the delivery pipe must be bled!
If the suction port is situated below and the pressure fluid level is below the pump,
take special care during the bleed process!
DANGER
