The piston pump is driven with compressed air (2). This compressed air moves the air
piston up and down in the air motor (1) and it also moves the the associated pump piston
up and down in the  uid section (6). At the end of each stroke, the compressed air  ow is
redirected by a reversing valve (9).
The working material is sucked up during the upwards stroke and is continuously conveyed
towards the product outlet (5) in both stroke directions.
Air motor (1)
The air motor with its pneumatic reverse (9) does not require pneumatic oil.
The compressed air is fed to the motor via an air regulator (11) and the ball valve (12).
Fluid section (6)
The  uid section has been designed as a piston pump with exchangeable ball valves. The
pump piston runs in two  xed packings which are self-adjusting by means of a pressure
spring, thus resulting in a long service life.
Between the air motor and the  uid section there is a separating agent cup (4) for holding
the separating agent.
