Operating conditions
Media	Mineral Oils (DIN 51524)	HFA and HFB	HFC
Temperature	-30°C + 100°C	+5°C + 50°C	-30°C + 40 °C
Pressure	<=400 bar	<=400 bar	<=400 bar
Speed	<=0,5 m/s	<=0,5 m/s	<=0,5 m/s
Note: The above data are maximum values, they may only be maintained for short periods of time and cannot be used at the same time simultaneously.

Maximum permissible sealing gap - S (mm)
Cross-section = (D-d)/2	150 bar	250 bar	400 bar
<=5	0,30	0,20	0,15
>5	0,35	0,25	0,20
Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is very important to use an S value lower than the above indicated numbers.
