Working Principle
When the pump turns ON (energised), the diaphragm will perform a
stroke to the solenoid side. This condition makes the pressure in the
pump chamber negative and the check valve on the OUT side is closed.
Fluid passed through the suction port then the check valve on the IN
side is sucked in the pump chamber.
When the pump turns OFF (de-energised), the diaphragm will perform
a stroke to the body side with return force of the return spring. Due to
this, the check valve on the IN side is closed, and fl uid in the pump
chamber is passed through the check valve on the OUT side and is
dispensed from the outlet.
Suction and dispensing are repeated with repetitive ON/OFF operation.

Dispense Volume Adjustment
The dispense volume per shot can be changed by rotating the dispensing volume adjusting screw.
When rotating the dispensing volume adjusting screw clockwise, the dispense volume
decreases. When rotating it counterclockwise, the dispense volume increases.
Remove the cap and loosen the lock nut while holding the dispensing volume adjusting
screw with a fl at blade screwdriver to prevent it from rotating. (Counterclockwise)
Rotate the dispensing volume adjusting screw to adjust the dispense volume.
Refer to the drawing on the right and the table below as reference for the range of
the dispensing volume adjusting screw.
∗
Do not apply excessive torque when rotating the dispensing volume adjusting
screw. If the screw is tightened too much, it may lead to product failure or cause
the screw to shear. Adjust the dispense volume gradually to avoid breakage of
the inner parts due to tightening the adjusting screw too much.
∗
When the dispensing volume adjusting screw is close to the maximum adjustment
level, the noise may be loud. In this case, turn the screw clockwise until the noise
is reduced.
