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.
7.4
Stopping of Operation
1. Turn off the motor.
2. Close the valve in the suction line to prevent dry running of
the pump.
3. Close the valve in the discharge line.
7.5
Pump Decommissioning
1. Turn off the motor.
2. Close the valve in the suction line.
3. Close the valve in the discharge line.
4. De-energize the pump.
5. Empty the pump.
6. Clean the pump as described in
.
7. Dry the pump.
8. Protect the interior of the pump from moisture, e.g., with sili-
ca gel.
9. Seal the pipe connections with caps to prevent penetration
of dirt and foreign objects.
10. Please see
for additional steps.

Cleaning in Place
7.6.1
CIP Process
The FSP Series pumps are suitable for the CIP (Cleaning In Place)
process. The following guidelines apply to the CIP process:
Example of a Cleaning Cycle
1. Perform preliminary flush with water.
2. Perform caustic flush with soda lye (NaOH, see
.
3. Perform intermediate flush with water.
4. Perform acid flush with nitric acid (HNO
3,
see
.
5. Flush with water.

7.6.2
SIP Process
Dry Running of Pump
Damage to shaft seal.
If vapor is flowing through the pipes, ensure that the pump
is off.
The FSP Series pumps can only be used with the SIP (Steriliza-
tion In Place) process with the prior approval of
Fristam
.
Suitability depends on the selected elastomers. The maximum
process temperature is 145°C.
In ATEX operation, temperatures might deviate, see supplemen-
tary ATEX manual, "Temperature limits".

Faults
For information on faults, possible causes, and remedies, please
see
Chapter 10.3, "Troubleshooting Table" page 28
8.1
Safety Instructions
– Danger of burning: Pumping of hot media can cause the
pump to become very hot.
Check the temperature before touching the pump.
– 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.
