When moving the pump or unit on wheels strictly attend to the following:
■ Pad lock the motor drive and secure against unintended starting up.
■ Move the pump unit carefully and slowly, especially where the ground is
uneven. Hazards of tipping!
■ 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.
■ Where fitted loosely, carefully watch the pipe bends when pumping.
Power of repulsion!
■ Where necessary, secure the pump unit additionally with support blocks.
3.2 Storage
The pumps are preserved for transport unless specified otherwise.
In cases of longer storage the pumps should be handled as follows
until installation:
■ 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 in a clean,
cool and dry environment.
Standard DIN 7716 summarizes detailed information on the storage
of rubber products, some of which is gathered here, and the following
notice applies to a storage for a period of up to six months.
General
Most of the rubber products may change their physical properties
under unfavourable conditions or if treated improperly, which will
result in a shorter lifetime.
Or they may become useless through excessive hardening, aging,
regenerating or permanent deformation, also because of blistering,
cracking or other damages appearing on the surfaces.
The changes may occur under the influence of oxygen, ozone, heat,
light, humidity, solvents or because of storing the products under
tension.
If stored and treated properly, the rubber products will keep their
properties, even over a long period of time (some years), almost
unchanged.
This does, however, not apply to uncured rubber compounds.
