Example of a Cleaning Cycle
1. Perform preliminary flush with water.
2. Perform caustic flush with soda lye (NaOH, see Table 3 "CIP
cleaning" ).
3. Perform intermediate flush with water.
4. Perform acid flush with nitric acid (HNO
3
, see Table 3 "CIP
cleaning" ).
5. Flush with water.
If values deviate from these specifications, please contact Fristam .
7.6.2 SIP process
NOTE
Dry Running of Pump
Damage to shaft seal.
 If vapor is flowing through the pipes, ensure that the pump
is off.
The pumps of the FPM and FSM series are only suited for SIP
(Sterilization In Place) procedures after consultation with
Fristam .
The suitability depends on the selection of the elastomers, the
magnets and the containment shell of the magnetic coupling.
The maximum process temperature is 145°C.
Temperatures with ATEX may deviate, see additional ATEX oper-
ation manual “Temperature application limit”.
8 Faults
For information on faults, possible causes, and remedies, please
see
Chapter 10.3 "Troubleshooting table", Page 19 .
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.
9 Maintenance
For information on maintenance intervals, please see
Chapter 10.2 "Maintenance intervals", Page 18 .
9.1 Safety instructions
– Danger of burning: Pumping of hot media can cause the
pump to become very hot.
 Check the temperature before touching the pump.
– Electric shock: As liquids flow through the unit, components
might become electrically charged.
 Connect the pipelines and the pump to an earthing con-
ductor.
– Uncontrolled escaping of liquid: Before any maintenance
and set-up work on the pump.
 Close the suction and pressure valves upstream and
downstream of the pump.
– Escaping liquids: Risk of corrosion and contamination.
 Before opening the pump casing, empty the pump.
– Risk of crushing injury: During maintenance tasks, the strong
magnetic field presents an inherent danger of injury.
 During the disassembly and assembly, only studs shall
be used in the casing for guiding purposes.
 To stay out of harm's way during the assembly, and do
not reach between the casing and the lantern.
– Contamination: Property damage due to contamination
 During the disassembly and the assembly of the mag-
netic coupling, clean installation conditions are a prima-
ry concern.
– Damage: Damage due to excessive forces
 Do not use excessive force during the disassembly and
assembly tasks.
9.2 Replacement Parts
Use of replacement parts that are not approved by Fristam can
lead to serious personal injury and material damage If you have
any questions regarding approved replacement parts, please
contact
Fristam .
Fristam registers all shipped pumps. The serial number of the
pump is needed for ordering of replacement parts from Fristam ;
see
– rating plate or
– number stamped into pump casing.
9.3 Lubricating the motor bearing
 Lubricate the motor bearings in accordance with the motor
manufacturer's specifications. See "
Supplier Documentation “
in the attached documents.
