* Reference medium approx. 1.000 mPas at 20 ° C.
** Maximum dispensing pressure and self-sealing decrease with decreasing viscosity.
*** Depending on viscosity and primary pressure of medium. All pressure details are maximum values for low-to-medium viscosity media (20,000
mPas).
‡Higher viscosity may be possible based on nozzle size and flow rate.
