Operation

6.2

Commissioning

6.2.1

Switching on

Pump set up and connected properly
Motor set up and connected properly
All connections stress-free and sealed
All safety equipment installed and tested for functionality
Pump prepared, filled and vented correctly

DANGER

Risk of injury due to running pump!

Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
Allow the pump to cool down completely before starting any
work.

DANGER

Risk of injury and poisoning due to pumped liquid spray-
ing out!

Use personal protective equipment when carrying out any
work on the pump.

NOTE

Risk of cavitation if suction flow is restricted!

Open the suction-side fitting and do not use it to regulate
the flow.
Do not open the pressure-side fitting beyond the operating
point.

NOTE

Material damage due to overheating!

Do not operate the pump for long periods with the pressure-
side fitting closed.
Observe the minimum flow rate

(

→

9.2.6 Flow rate,

Page 29).

NOTE

Material damage as a result of dry running!

Make sure the pump is filled properly.

1. Open the suction-side fitting.
2. Close the pressure-side fitting.
3. Switch on the motor and check it for smooth running.
4. Once the motor has reached its nominal speed, open

the pressure-side fitting slowly until the operating point is
reached.

5. Make sure temperature change is smaller than 5 K/min for

pumps with hot fluids.

6. After the initial stress due to the pressure and operating

temperature, check that the pump is not leaking.

7. If leaks are present at the casing seals or connection

flanges, proceed as follows:
–

Switch off motor.

–

Close the control valves.

–

Remedy the leaks.

6.2.2

Switching off

Pressure-side fitting closed (recommended)

WARNING

Risk of injury due to hot pump parts!

Use personal protective equipment when carrying out any
work on the pump.

1. Switch off motor.
2. Check all connecting bolts and tighten them if necessary

(only after initial commissioning).

6.3

Shutting down the pump

DANGER

Risk of injury due to running pump!

Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
Before all installation and maintenance work, disconnect
the motor from the mains and secure it against being
switched back on again.

DANGER

Risk of electrocution!

All electrical work must be carried out only by qualified elec-
tricians.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.

WARNING

Risk of injury and poisoning due to hazardous pumped
liquids!

Use protective equipment for any work on the pump.
Collect leaking liquid safely and damage fitting in accor-
dance with local regulations.
