5.2 MODE OF OPERATION
The piston pump is driven with compressed air (8). This compressed air moves the air piston
in the air motor (1) and the associated pump pistons in the fluid section(5) up and down. At
the end of each stroke, the compressed air is redirected by a reversing valve (11). The
working material is sucked up during the upwards stroke and is continuously conveyed
towards the product output (10) in both stroke directions.
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.
