2. Operating principle
The APN-085-W is a gas-liquid transfer pump with a small
size diaphragm and special valves, and is designed for
built-in application.
The rotary motion of the motor is converted via a con-
necting rod to the reciprocation of the diaphragm in the
pump chamber, where the mixture of gas and liquid is
transferred from the inlet to outlet.
