11.5 Motor protection
Take sufficient measures to prevent the motor being able to be started while work is taking place on the
pump/pump unit. This is particularly of importance with motors that are remotely started.
Follow the procedure below:
11.5.1 Electric motor
•
Switch the operating switch on the pump/pump unit to “off”.
•
Switch the pump switch on the switch box to “off”.
•
Secure the switch box or hang a warning sign on the switch box.
•
Remove the fusing and take it to the assembly place.
•
Only remove the protective cover over the coupling after the pump/pump unit has become fully
stationary.
11.5.2 Diesel motor
•
Switch the ignition key or turning knob at the pump/pump unit to “off”.
•
Remove the battery cable from the battery.
•
Secure the switch box or hang a warning sign on the switch box.
•
Remove the fusing and take it to the assembly place.
•
Only remove the protective cover over the coupling after the pump/pump unit has become fully
stationary.
11.6 Preservation
When the pump/pump unit is not to be used for longer periods it must first be fully emptied. Then treat
internal parts with a mineral oil. Shut off the suction flange imperviously. Fill the pump with preservative
and slowly turn the rotating parts by hand. Then shut off the delivery flange imperviously.
When present, connections for rinsing, circulation or cooling must also be closed. All not painted parts
and the rotating parts must be provided with a coat of preservative. The choice of preservative depends on
the materials and the application. The pumps must be stored covered and well ventilated. Temperatures
below freezing point and high air humidity must be avoided.
11.7 external cleaning
Keep the surface of the pump as clean as possible. This simplifies maintenance and checks.
If the pump is cleaned this must be done with the correct cleaning material for
the technical properties.
Make sure that during cleaning the resources used for this and the dirt
particles are collected in an environmentally friendly way.
Avoid temperature shocks: do not spray water on a heated pump. Sudden
cooling can crack the pump components.
Make sure that the cleaning agent does not penetrate the ball bearing space.
With sealed bearings prevent the cleaning agent from damaging the rubber
seals.
