7. Taking the product out of operation
1.
Always close the outlet gate valve before stopping the pump.
Close the valve slowly to prevent hydraulic shock.
2.
Switch off and lock off the power supply to the motor.
3.
For overnight or temporary shutdown periods under non-
freezing conditions, the pump may remain filled with liquid.
Make sure that the pump is fully primed before restarting.
4.
For long shutdown periods or to isolate the pump for
maintenance, close the inlet and outlet gate valves. If no inlet
gate valve is used and the pump has positive inlet pressure,
drain all liquid from the inlet line to stop the liquid flow into the
pump inlet.
5.
If applicable, uninstall water flush lines.
6.
Remove the plugs in the pump drain and vent holes, as
required, and drain all liquid from the housing.
7.
In case of freezing conditions during long shutdown periods,
drain the pump completely and remove the packing, if
applicable. Blow out all liquid passages and pockets with
compressed air. Freezing of the pumped liquid can also be
prevented by filling the pump with an antifreeze solution.
8.
Rotate the shaft by hand monthly to coat the bearings with
lubricant and impede oxidation and corrosion.
9.
Follow the motor manufacturer's storage recommendations
where applicable.
