7 Disassembly and assembly
7.1 Precautionary measures

Take adequate measures to avoid that the motor is started while you are
working on the pump. This is especially important for electric motors with
remote control:
• Switch the operating switch near the pump (if available) to "OFF".
• Switch off the pump switch on the switchboard.
• If necessary remove the fuses.
• Hang a danger board near the switchboard cabinet.
7.2 Special tools
Assembly and disassembly work requires no special tools. However, such tools can
make certain jobs easier, for instance replacing the shaft seal. If such is the case it will be
indicated in the text.
7.3 Liquid draining
!
Make sure no liquid gets into the environment!
Before starting any disassembly the pump should be drained through the drain plug
(0320). If possible, also drain the suction bend to a certain extent (if provided with a
suction bend (0400) through drain plug (0350)). If necessary, close the valves in the
suction and delivery pipe and in the flushing or cooling supply lines to the shaft seal. Also
drain the self-priming section by disconnecting the piping P, S and W.
If the pump processes harmful liquids, take the following precautions:
1 Wear protective gloves, shoes, glasses, etc.
2 Flush the pump properly.
3 Make sure no liquid gets into the environment.
4 Refit the drain plug.
7.4 Item numbers
If no specific figure numbers are stated, then the item numbers used in these instructions
refer to the cross section drawings and parts lists, which can be found in chapter 9.
The connection markings P, S and W on the self-priming section are explained in
paragraph 3.7.3 "Indication of connections" for the Service liquid tank configuration TL or
paragraph 3.8.3 "Indication of connections" for the Float de-aerator configuration VL.
