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 fluid section (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 in the fluid
section is produced by hydraulic oil, which is moved by the piston rod in the fluid section.
With every stroke of the piston rod, working product is sucked in and delivered to the spray
gun at the same time.
5.2.1 AIR MOTOR
The air motor (4) 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 (9) has been designed as a double diaphragm pump with exchangeable
inlet and outlet valves. With the mixing block (17), upstream relief valves (15) can be switched
from "Spraying mode" to "Product circulation mode".
