INSTRUCTIONS FOR THE CLEANING OF SEMPERIT FOOD QUALITY HOSES

Semperit food-quality hoses are in compliance with requirements specified for the respective product. 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 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.

Special cleaning agents:
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 hoses LM2, LM3, LMD NBR, LMH NBR, LOSP, LMSP, LME, LM4 and LM4S 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

Hoses LMW-AQUALINE, LMU und LMUS, LM1-EPDM and LM1S-EPDM, LMD, 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 that subjecting the hose to extreme conditions for longer periods can shorten life of the hose.
