Liquid pulsation damper 

Use 

KNF Flodos BA_FPD_EN_04_069182 
Translation of Original Operating and Installation Instructions

 

  Because the cleaning requirements of the liquid pulsation 

dampers depend on the application, KNF is unable to guaran-
tee cleaning options. The responsibility for cleaning therefore 
lies with the user. While the NSF/ANSI 169 standard regulates 
OEM products, it does not define cleaning methods for specific 

OEM products. 

  All parts in contact with the medium can be replaced as spare 

parts without losing the certification. Component parts cannot 
be traded as certified parts. When replacing parts/assemblies 

only use original KNF parts. 

 

Improper use 

2.2.

The liquid pulsation damper must not be operated in a potentially 
explosive atmosphere. 
For special modifications outside the standard technical specifica-

tions, please contact a KNF pump specialist.
