I Ensure a stable position of the pump or unit at the operating /storage place and
secure it by actuating all clamping devices on all the wheels or rollers against
voluntary moving away.
I Where fitted loosely, carefully watch the pipe bends when pumping. Power of
repulsion!
I Where necessary, secure the pump unit additionally with support blocks.
3.2 Storage
The pumps are only preserved for transport and short term storage unless specified
otherwise.
In cases of long term storage the pumps should be handled as follows until
installation:
L Stator:
If the pump is not to be used immediately, then the elastomer along the contact line
between rotor and stator may become permanently distorted (compression-set). This
will increase the break away torque.
Therefore, the stator should be removed and kept separately.
Standard DIN 7716 summarizes detailed information on the storage of rubber
products, extracts from which are stated here.
The following applies for a storage period of up to six months.
General:
Most rubber products may change their physical properties under unfavourable
conditions or if treated improperly, which will result in a shorter lifetime. They can
become unsuitable for use through excessive hardening, ageing, degeneration or
permanent deformation, or because of blistering, cracking or other damage appearing
on the surfaces.
These changes may occur under the influence of oxygen, ozone, heat, light, humidity,
solvents or because of storing the products under load.
If stored and treated properly, rubber products will retain their properties even during
long term storage (some years), with little change. However this does not apply to
uncured rubber compounds.
