Minimum fluid level
NOTE
For pump sets with cutters we recommend continuing pump operation for about 10
seconds after the minimum suction level has been reached (see dimension RS in the
outline drawing).
Operation with a dropping fluid level up to dimension R1 (see outline drawing) is
permissible. Please note that during that time frequent starting and stopping of the
pump set must be avoided.

The power input of the pump set will change in proportion to the density of the fluid
handled.
CAUTION

Motor overload!
▷
Observe the information about fluid density in the data sheet.
▷
Make sure the motor has sufficient power reserves.
