8.3. MAINTENANCE OF THE SEALS
SEALS REPLACEMENT
Preventive maintenance Replace after twelve (12) months. We also recommend repla-
cing the gaskets during mechanical seal replacement.
Maintenance after a leak Replace at the end of the process
Scheduled maintenance
Regularly check that there are no leaks and that the blender
is operating correctly.
Keep a maintenance record of the pump.
Use statistics to plan inspections.
Lubrication
During assembly, use soapy water or oil compatible for the
food industry when tting the di󰀨erent gaskets to allow them
to slide better.
This pump, just like any other machine, requires maintenance. The instructions contained in this
manual cover the identication and replacement of spare parts. The instructions are aimed at
maintenance personnel and those responsible for the supply of spare parts.
Carefully read chapter 9. Technical Specications.

INOXPA S.A.U. 01.011.30.11EN · (0) 2023/03

8.6. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may give
raise to skin burns.
Use rubber gloves during cleaning procedures.
Always use protective goggles.
8.6.1. Automatic CIP (clean-in-place)
If the pump is installed in a system with a CIP process, it is not necessary to disassemble the blender.
If the automatic cleaning process is not provided, proceed to disassemble the blender as indicated
in the chapter 8.7. Disassembly and assembly of the pump.
ATTENTION
Check the concentration of the cleaning solutions. Incorrect concentrations may lead to
the deterioration of the blender seals.
To remove any traces of cleaning products ALWAYS perform a nal rinse with clean water at the end
of the cleaning process.
Two types of solutions can be used for CIP processes:
a. alkaline solution: 1% by weight of caustic soda NaOH a 70ºC (150ºF). To make this solution:
1 kg NaOH + 100 l H2O1= cleaning solution
2,2 l NaOH 33% + 100 l H2O = cleaning solution
b. acid solution: 0,5% by weight of nitric acid HNO3 a 70ºC (150ºF). To make this solution:
0,7 l HNO353% + 100 l H2O = cleaning solution
1) only use chlorine-free water to mix with the cleaning agents
8.6.2. Automatic SIP (sterilization-in-place)
The steam sterilisation process is applied to all equipment including the pump.
Do NOT operate the equipment during the steam sterilisation process.
The parts and the materials will not su󰀨er damage provided the instructions set out in
this manual are followed.
Cold liquid cannot be introduced until the pump temperature is below 60ºC (140ºF).
The blender generates a substantial pressure loss through the sterilisation process. We
recommend the use of a bypass circuit provided with a discharge valve to ensure that the
steam or overheated water sterilises the entire circuit.
Maximum conditions during the steam or overheated water SIP process:
a. maximum temperature: 140ºC / 284ºF
b. maximum time: 30 min
c. cooling: sterile air or inter gas
d. materials: EPDM (recommended)
