7Operation
7.1 Safety Instructions
– Danger of bursting: If the allowable pressure or temperature
range is exceeded, the pump may burst or become leaky.
Maintain the pump pressure and temperature within the
specified ranges. See "Order-Related Documents" in the at-
tached documents.
– Danger of bursting: Cold extinguishing agents used to extin-
guish a pump fire can cause the hot pump to burst.
Do not cool the pump down excessively when extin-
guishing the fire.
– Danger of burning: Pumping of hot media can cause the
pump to become very hot.
Check the temperature before touching the pump.
Only touch the pump if you are wearing suitable gloves.
– Noise emissions: The A-weighted sound pressure level of the
pumps can be greater than 80 dBA.
Always wear ear protectors in the vicinity of the running
pump.
The local noise exposure regulations must be complied
with.
See noise emission values for the pumps: Chapter 10.1.2,
"Noise Emissions" page 27.
– Destruction of shaft seal when pump runs in reverse direc-
tion. Reverse running destroys the springs in the shaft seal.
Always operate the pump in the direction of rotation. See
Chapter 2.4.3, "Direction of Rotation" page 6.
– Pump running in reverse direction despite emergency shut-
off: If the pump is shut off using the emergency shut-off
function, the pumping medium in the discharge line will
flow in reverse direction through the pump.
Install a check valve.
7.2 Commencement of Operation
Dry Running of Pump
If the pump runs without a pumping medium, the back shaft
seal will be damaged.
Ensure that the pumping medium always reaches the upper
edge of the outlet side in the pump before and during oper-
ation.
Damage to Double Shaft Seals
If the pump runs without a sealing medium, the shaft seal will
be damaged.
Ensure that during operation:
The sealing liquid flows with the necessary pressure through
the double shaft seal.
The prescribed sealing fluid pressure is specified in the "Or-
der-related documents" in the sectional drawing of the shaft
seal. The "Order-related documents" are included in this op-
erating manual.
– Negative pressure in the seal chamber is not allowed.
If no pressure is noted in the "Sectional drawing of the shaft
seal", the following applies:
– A max. pressure of 0.2 bar is allowed for seals to which
sealing fluid is applied without pressure or which are
flushed.
The temperature of the sealing liquid is maintained at
T < 70 °C.
1. Open the valve in the suction line.
2. Close the valve in the discharge line.
3. Fill the pump and the suction line up to the upper edge of
the pump with pumping medium. Allow any air pockets that
are present to escape.
4. Turn on the motor.
The pump now pumps against the closed valve in the dis-
charge line. This will limit the starting current.
5. Slowly open the valve in the discharge line and adjust to the
working point.
7.3 Monitoring of Operation
During operation heed the following points:
– Damage to shaft seal: Regulation of the pump output via a
suction-side valve can lead to cavitation and dry running of
the pump.
Regulate the pump output only by means of the dis-
charge-side valve.
– Shearing off of shaft: Foreign objects in the pumping medi-
um can lead to impeller blockage and hence to shearing off
of the shaft.
Rule out the possibility of foreign objects in the pumping
medium. If necessary, install a screen, a settling tank, or a
filter.
Install a current limiter to protect the motor.
– Damage to pumping medium: If during operation the valve
in the discharge line is closed abruptly or for a long period of
time, water hammers can occur in the pump. Water ham-
mers can damage the pump and the pumping medium.

/ / FSP SERIES / / /

During operation do not close the valve in the discharge
line abruptly or for a long period of time.
– Damage to pump: Exceeding of the output can lead to dam-
age of the pump and the shaft seals.
Do not exceed the maximum speed of 3,600 rpm.
Do not overload the pump by pumping highly viscous
media.
– Damage to motor during operation with frequency convert-
er: If the speed is too low, the motor will overheat.
Please refer to the "Motor Supplier Documentation" in the
attached documents.
