6.1.3
Shutdown
CAUTION
Uncontrolled backflow of the fluid from the discharge tube
Damage to the pump set!
▷
Prevent any uncontrolled backflow of the fluid handled with suitable means.
▷
Control the fluid backflow.
6.2 Operating limits
DANGER
Non-compliance with operating limits
Damage to the pump set!
▷
Comply with the operating data indicated in the data sheet.
▷
Avoid operation with flow rates below the limit Q
min
.
▷
Never operate the pump set outside the limits specified below.
6.2.1
Temperature of the fluid handled
The pump set is designed for transporting liquids. The pump set is not operational
under freezing conditions.
CAUTION
Danger of frost/freezing
Damage to the pump set!
▷
Drain the pump set or protect it against freezing.
Refer to the maximum permissible fluid and ambient temperature indicated on the
name plate and in the data sheet.
6.2.2
Density of the fluid handled
The power input of the pump increases in proportion to the density of the fluid
handled.
CAUTION
Impermissibly high density of the fluid handled
Motor overload!
▷
Observe the information on fluid density in the data sheet.
▷
Make sure the motor has sufficient power reserves.
6.2.3
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 is to be expected. In this case, reduce the commonly
recommended inspection intervals.
6.2.4
Supply voltage
The maximum permissible deviation in supply voltage is ± 5 % of the rated voltage.
The voltage difference between the individual phases must not exceed 1 %.
