6.2.3.2 Density of the fluid handled
The power input of the pump set will change in proportion to the density of the fluid
handled.
CAUTION
Impermissibly high density of the fluid handled
Motor overload!
▷ Observe the density specifications in the data sheet and, if applicable, in the
ATEX declaration of conformity.
▷
Make sure the motor has sufficient power reserves.
6.2.3.3 Abrasive fluids
Do not exceed the maximum permissible solids content specified in the data sheet.
When the pump handles fluids containing abrasive substances, increased wear of the
hydraulic system and shaft seal are to be expected. In this case, reduce the commonly
recommended inspection intervals.
6.2.3.4 Fluid temperature
The maximum permissible fluid temperature is indicated in the data sheet or ATEX
declaration of conformity. For a higher fluid temperature consultation with KSB is
required.
6.2.3.5 Viscosity of the fluid handled
The power input of the pump set will change in proportion to the viscosity of the
fluid handled.
CAUTION
The fluid handled has a higher viscosity than permitted.
Risk of motor overload!
▷ Observe the viscosity limits for the fluid handled given in the data sheet.
▷ Make sure the motor has sufficient power reserves.
6.2.4 Maximum permissible speed
Comply with the rotational speed indicated on the name plate.
