5.2.2 Fluid section
The fluid section is designed as a piston pump with flap valves. The pump piston runs in the
upper fixed packings which are self-adjusting by means of a pressure spring. This results in
the packing having a long service life. There is a spacer (12) between the air motor and the
fluid section. It serves to collect the separating agent.

Safety valve
WARNING
Overpressure!
Danger to life from bursting device components.
4Never change the safety valve setting.
The air motor is fitted with a safety valve. The safety valve (11) has been set and sealed at the
factory. In case of pressures over and above the permissible operating pressure, the valve,
which is held with a spring, automatically opens and releases the excess pressure. As well as
handling pressure limits, the valve is also used as a pressure relief valve for the air motor.
