DANGER
Risk of potentially explosive atmosphere inside the pump
Explosion hazard!
▷
The pump internals in contact with the fluid to be handled, including the seal
chamber and auxiliary systems must be filled with the fluid to be handled at all
times.
▷
Provide sufficient inlet pressure.
▷
Provide an appropriate monitoring system.
CAUTION
Increased wear due to dry running
Damage to the pump set!
▷
Never operate the pump set without liquid fill.
▷
Never close the shut-off element in the suction line and/or supply line during
pump operation.
1. Vent the pump and suction line and prime both with the fluid to be handled.
2. Fully open the shut-off element in the suction line.
3. Fully open all auxiliary feed lines (barrier fluid, flushing liquid, etc.), if any.
NOTE
For design-inherent reasons some unfilled volume in the hydraulic system cannot be
excluded after the pump has been primed for commissioning/start-up. However,
once the motor is started up the pumping effect will immediately fill this volume
with the fluid handled.
6.1.4 Start-up
DANGER
Formation of a potentially explosive atmosphere inside the pump
Explosion hazard!
▷
The fluid for priming the pump must not be combustible.
▷
When the fluid for priming the pump is taken from a potentially explosive
atmosphere, make sure that no potentially explosive atmosphere can enter the
pump.
DANGER
Non-compliance with the permissible pressure and temperature limits if the pump
is operated with the suction and/or discharge line closed.
Explosion hazard!
Hot or toxic fluids escaping!
▷
Never operate the pump with the shut-off elements in the suction line and/or
discharge line closed.
▷
Only start up the pump set with the discharge-side shut-off element slightly or
fully open.
