Semperit food-quality hoses are in compliance with
the recommendation XXI:2002 of the BGVV
(Germany) and/or other national requirements. This
ensures that no noxious substances affect food stuffs.
Please follow the instructions mentioned below to
guarantee trouble-free performance of the hose, avoid
any modification in the smell and taste of the
transported goods and ensure the long life of the
hose.
First cleaning:
Normally new hoses do not cause any modification
in smell or taste of the transported food stuffs . If hoses
have a typical "rubbery smell" these hoses should be
treated before their initial use for 24h with 1%
phosphoric acid, followed by a 2% sodium hydroxide
solution or 2% sodium carbonate solution and finally
rinsed with clear water.
Standard cleaning:
Treat briefly with 2% sodium
hydroxide solution or 2% sodium carbonate solution
at 80° C, then rinse with hot and cold water.
Special cleaning agents:
Naturally nearly all kinds of industrial cleaning agents
and disinfectants can be used to clean Semperit food
quality hoses. The cleaning process must be carried
out in the concentrations and at the temperatures for
rubber hoses indicated by the manufacturers of the
cleaning agents in question. The use of CIP facilities
together with suitable cleaning procedures is also
recommended.
Resistance to cleaning agents:
Cleaning under normal conditions should not cause significant changes in hose properties .
For the hoses LM2, LM3, LM4/SF 1500 please follow the peak values for cleaning agents and temperatures
indicated below:
- Acids (e.g. phosphoric acid, nitric acid, sulfuric acid and
cleaning agents containing these ingredients)
1 -2 %
25°C
- Alkalis (e.g. sodium hydroxide solution, sodium carbonate
solution and cleaning agents containing these ingredients)
2 %
80°C
- Desinfectants (e.g peracetic acid)
500 ppm
25°C
The hoses LMU and LMUS, LM1-EPDM and LM1S-EPDM, LMB and LMBS are also resistant to extreme cleaning
conditions, if the indicated concentrations and temperatures are used only rarely:
- Acids (e.g. phosphoric acid, nitric acid, sulfuric acid and
cleaning agents containing these ingredients)
2 % 40°C
- Alkalis (e.g. sodium hydroxide solution, sodium carbonate
solution and cleaning agents containing these ingredients)
5 %
90°C
- Desinfectants (e.g. peracetic acid)
2000 ppm
40°C
Please note subjecting the hose to extreme conditions for longer periods can shorten life of the hose.
