FUNCTION
Fluid section (9)
The fl uid section has been designed as a piston pump with exchangeable ball valves and
continuous lower packing. The pump pistons and working surface of the cylinder are hard
chrome-plated. The upper and lower packings are automatically adjusted by pressure
springs to achieve a long service life.
Between the air motor and the fl uid section there is a separating agent cup (7) for holding
the separating agent.

WARNING
Function principle
The piston pump is driven with compressed air (2). This compressed air moves the air
piston up and down in the air motor (4) and it also moves the associated pump piston up
and down in the fl uid section (9).
In the control housing (1), the air pressure is redirected at the end of each stroke with the
help of the reversing valve. The working material is sucked up during the upwards stroke
and is continuously conveyed towards the material outlet (8) in both stroke directions.
Air motor (4)
The air motor with its pneumatic reverse (1) does not require pneumatic oil.
The compressed air is fed to the motor via the air regulator (2) and the ball valve (3).
The air motor is fi tted with a safety valve. The safety valve 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.
