6 Commissioning/Start-up/Shutdown
6.1 Commissioning/start-up
6.1.1 Prerequisites for commissioning/start-up
Before starting up the pump set make sure that the following requirements are met:
▪
The pump set has been properly connected to the power supply and is equipped
with all protection devices.
▪
The pump has been primed with the fluid to be handled.
▪
The direction of rotation has been checked.
▪
All auxiliary connections required are connected and operational.
▪
After prolonged shutdown of the pump (set), the activities described in (
⇨
Section 6.3 Page 21) have been carried out.
6.1.2 Checking the shaft seal
The mechanical seal only leaks slightly or invisibly (as vapour) during operation.
Mechanical seals are maintenance-free.
6.1.3 Priming and venting the pump
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.
WARNING
Hot fluid escaping under pressure when the vent plug is opened
Risk of electric shock!
Risk of scalding!
▷
Protect the electric components against escaping fluid.
▷
Wear protective clothing (e.g. gloves).
NOTE
For design-inherent reasons a remaining gas 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.
