8 Cleaning in Place
NOTICE
Pumping Media or Cleaning Solutions at Different High Tem-
peratures
Material damage to rotors, shafts, and pump casing.
►
Avoid temperature changes in pumping media and cleaning
solutions when the pump is running.
► Before starting the pump bring all pump components that
come into contact with the product to the same tempera-
ture.
►
Provide a larger clearance. See Table 19 , "Clearances for 20
bar rotors," page 26 .
8.1 CIP Process
The FKL Pump Series pumps are suitable for the CIP (Cleaning In
Place) process. The following guidelines apply to the CIP pro-
cess:
Example of a Cleaning Cycle
1. Perform preliminary flush with water.
2. Perform caustic flush with lye (NaOH; see Table 2 , "CIP
cleaning," page 14 ).
3. Perform intermediate flush with water.
4. Perform acid flush with nitric acid (HNO
3
;
see Table 2 , "CIP
cleaning," page 14 ).
5. Flush with water.
The pump's differential pressure should be 2–3 bar so that ade-
quate flow rates are reached in the pump.
If values deviate from these specifications, please contact Fris-
tam .
8.2 SIP Process
NOTICE
Dry Running of Pump With Vapor
Damage to shaft seal.
► If vapor is flowing through the pipes, ensure that the pump
is off.
The FKL Pump Series can only be used with the SIP (Sterilization
In Place) process with the prior approval of
Fristam .
Suitability depends on the selected elastomers.
The maximum process temperature is 145°C.
9 Faults
For information on faults, possible causes, and remedies, please
see
Chapter 11.3, "Troubleshooting Table," page 29 .
9.1 Safety Instructions
Hot Pump Surface
Contact burns from touching the pump. Pumping of hot media
can cause the pump to become very hot.
► Let the pump cool down completely before working on it.
► Check the temperature before touching.
► Only touch the pump if you are wearing heat-resistant
gloves.
Medium Process Temperature [°C]
NaOH (approx. 1% to 2%) 80 to 85
HNO
