Safety
The manufacturer accepts no liability for damage caused
by disregarding any of the documentation.
2.1
Intended use
•
Only use the pump with suitable media (
ĺ
resistance lists).
•
When using the pumps for solid particles, agree use in
advance with the manufacturer.
•
Do not use pump for combustible or explosive
À
uids.
•
Adhere to the operating limits and size-dependent mini-
mum
À
ow rates.
•
Avoid cavitation:
–
Open the suction-side
¿
tting and do not use it to regu-
late the
À
ow.
–
Do not open the pressure-side
¿
tting beyond the
agreed operating point.
•
Avoid overheating:
–
Do not operate the pump while the pressure-side
¿
tting
is closed.
•
Avoid damage to the motor:
–
Do not open the pressure-side
¿
tting beyond the
agreed operating point.
–
Note the maximum permissible number of times the
motor can be switched on per hour (
ĺ
manufacturer's
speci
¿
cations).
•
Only use the pump as part of large systems/tools.
•
Consult with the manufacturer regarding any other use of
the device.
Prevention of obvious misuse (examples)
•
Observe pump limits of use regarding temperature, pres-
sure,
À
ow and speed (
ĺ
data sheet).
•
The power consumption of the pump increases as the spe-
ci
¿
c gravity of the pumped
À
uid increases. Adhere to the
permissible speci
¿
c gravity in order to eliminate the pos-
sibility that the pump, coupling and motor become over-
loaded (
ĺ
data sheet).
A lower speci
¿
c gravity is permissible. Adapt the auxiliary
systems accordingly.
•
Pumps used with water as the pumped liquid must not be
used for foodstuffs or drinking water. Use for food or drink-
ing water only if speci
¿
ed in the data sheet.
•
The type of installation should be selected only in accor-
dance with these operating instructions. For example, the
following are not allowed:
–
Hanging base plate pumps in the pipe
–
Overhead installation
–
Installation in the immediate vicinity of extreme heat or
cold sources
–
Installation too close to a wall
2.2
