MODE OF OPERATION
The double diaphragm pump is driven with compressed air. This compressed air moves the
air piston in the air motor (4), and consequently the piston rod in the pressure stage (9), up
and down. At the end of each stroke the compressed air is redirected by a reversing valve
and the control piston. The up-and-down movement of both diaphragms within the fluid
section is produced by hydraulic oil, which is moved by the piston in the pressure stage.
With every stroke of the piston rod, working material is sucked in and delivered to the
spray gun at the same time.
5.2.1 AIR MOTOR
The air motor with its pneumatic reverse (1) does not require pneumatic oil. The compressed
air is fed to the motor via the air pressure regulator (2) and the ball valve (3).
5.2.2 FLUID SECTION
The fluid section has been designed as a double diaphragm pump with exchangeable
inlet and outlet valves. Change between "spraying mode" and "circulation mode" using
the relief valve (7).
