Operating conditions: Process

The maximum permitted temperature at the process connection is determined by the O-ring version
ordered:
Device O-ring material
FMP53 EPDM (Freudenberg 70 EPDM 291)
FFKM (Kalrez 6221)
FKM (PPE V70SW)
1) Tested acc. to 3-A Sanitary Standard 18-03, Class II
2) Tested acc. to USP <88> Class VI - 121°C
3) Tested acc. to 3-A Sanitary Standard 18-03, Class I
4) Tested acc. to USP <88> Class VI - 121°C
Device Process pressure
FMP53 –1 to 16 bar (–14.5 to 232 psi)
This range may be reduced by the selected process connection. The pressure rating (PN) specified on
the flanges refers to a reference temperature of 20 °C. Pay attention to pressure-temperature
dependencies.
