6 Temporary Shutdown
After stopping the pump empty and if necessary rinse it or resp. apply anti-freezing
agent if:
- the medium might freeze due to the temperature surrounding the pump. Especially
where there is a danger of frost if the pump is installed outside a building
- the medium tends to solidify or harden
- the medium tends to glue up the shaft seal
Caution with biogas plants:
Pressure can build up in the plant when it is shut down!
You should therefore ensure that this pressure can escape.
6.1 Stator
When there is a shutdown of more than 6 months, the rotor can permanently deform
the stator at the contact surfaces (compression-set).
This will increase the break away torque.
For this reason, the stator should be removed (see Section 9), and stored in a cool,
dry place in air tight package to give protection against light and air (see also Section
3.2).
6.2 Rotor
Remove ceramic rotors (please observe Section 10!) and store away, safe in the
original packing.
Support other rotors on wooden blocks and cover to protect them from mechanical
damage, after the stator has been removed.
Rotors not of stainless steels:
Protect the rotor surfaces against corrosion with protective grease.
Remove the grease before re–installing the stator and clean the rotor
thoroughly in order to avoid unsuitability of the grease with the
pumping medium or the stator material.
