5.2.1 Air motor
The air motor with its pneumatic reverse (11) does not require pneumatic oil. The
compressed air is fed to the motor via an air regulator (7) and the ball valve (13). The air
motor is fitted with a safety valve (4) in accordance with Chapter Protective and Monitoring
Equipment [819].
5.2.2 Fluid section
The fluid section has been designed as a piston pump with exchangeable ball valves. The
hard chrome-plated pump piston runs in two fixed packings which are self-adjusting by
means of a pressure spring, thus resulting in a long service life. Between the air motor and
the fluid section there is a separating agent cup (9) for holding 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 (10) has been set and sealed at the
factory. In case of pressures over and above the permissible operating pressure, the spring-
loaded valve, 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.
