6.1.2
Priming and venting the pump
DANGER
Risk of potentially explosive atmosphere inside the pump
Explosion hazard!
▷ Before starting up the pump, vent the suction line and the pump and prime
them with the fluid to be handled.
DANGER
Shaft seal failure caused by insufficient lubrication
Hot fluid may escape!
▷ Before starting up the pump set, vent the pump and suction line and prime
both with the fluid to be handled.
1. Close all drains and drain lines.
2. Vent the pump and suction line and prime both with the fluid to be handled.
In case of suction lift operation, evacuate the pump.
3. Fully open the shut-off element in the suction line.
4. If the discharge line is equipped with a check valve, the shut-off element in the
discharge line may remain open as long as there is some back pressure. If this is
not the case, the shut-off element in the discharge line must be closed.
5. Fully open all auxiliary connections (barrier fluid, flushing liquid, etc).
