Check safety devices
Qualified personnel must connect and check safety devices on a regular basis for proper function, especially
after doing maintenance and repair work, before restarting.
Risk of injury when loading and transporting the pump or the pump unit
•
Use the lifting eye bolts on the pumps only for lifting the pump without mounted parts (for example,
the motor).
•
The unit may only be transported suspended or screwed to a Euro pallet.

Fig.
“Transport aids”.
•
During loading operations and when setting down the pump or the pump unit, it may be begin to swing
or fall. Risk of crushing! Therefore:

The loading and transporting may only be carried out by specially trained persons.

Standing under raised loads is prohibited. Direct persons out of the danger area.
Risk of injury from stumbling on slippery floor
•
Keep work station clean and clean up any auxiliary materials, operating materials and medium residue
that may be present, especially before maintenance and repair work on the pump or the pump unit.
•
Caution when temperatures are below freezing - keep workplace free of ice.
Closed pipe
Pumping must not take place against a closed pipe. The pump shaft seals or even the pump housing or the
pipe may be damaged or destroyed by the resulting high pressure. A pressure monitoring unit is optionally
available from us (setting at 10 % over the nominal pressure)

QD cover".
•
Attention! Before start-up, refill with fluid.
High viscosity medium
When using the pump for a very viscous medium, the pump speed must be reduced according to the
material's viscosity, to prevent the suction flow from breaking off on the suction side (cavitation protection).
Pumps with a mechanical seal consisting of the material combination SiC-SiC:
To avoid adhesion of the mechanical seal faces this pump needs to be rotated (at least one revolution) every
two months when not in service.
