▷

Drain the pump and release the pump pressure. (

Section 7.3, Page 38)

▷

Shut off any auxiliary feed lines.

▷

Allow the pump set to cool down to ambient temperature.

WARNING

Components with sharp edges

Risk of cutting or shearing injuries!

▷

Always use appropriate caution for installation and dismantling work.

▷

Wear work gloves.

NOTE

The pump casing can remain installed in the piping for further dismantling.

1. Disconnect the power supply (e.g. at the motor).

2. Disconnect and remove all auxiliary pipework.

3. Remove coupling guard 681.

4. Remove the coupling spacer of coupling 848, if any.

5. Drain the oil .

7.4.3 Separating the pump from the piping

The pump set has been switched off properly.

The shut-off elements in the suction line and discharge line have been closed.

Any auxiliary connections have been closed.

The pump has been drained and the pump pressure has been released.

1. Disconnect any auxiliary feed lines.

2. Remove the discharge nozzle and suction nozzle from the piping.

NOTE

After the pump set has been dismantled, the suction casing should be cleaned with
water. Suitable protective clothing is recommended.
