7 Disassembly and assembly
7.1 Precautionary measures
ƽ 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 Draining
! Make sure no liquid or oil gets into the environment!
7.3.1 Liquid draining
Before starting any disassembly the pump should be drained.
1 If necessary, close the valves in the suction and delivery pipe and in the flushing or
cooling supply lines to the shaft seal.
2 Remove the blind flange (1930).
3 If harmful liquids are pumped wear protective gloves, shoes, glasses, etc., and
thoroughly flush the pump.
4 Refit the blind flange.
7.3.2 Oil draining
If the pump is designed with oil lubricated bearings:
1 Remove the magnetic drain plug (2150).
2 Drain the oil.
3 Refit the magnetic drain plug.
ƽ If possible, wear protective gloves. Regular contact with oil products may
result in allergic reactions.
