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.

Tighten the lock nut while holding the dispensing volume adjusting screw with a fl at 
blade screwdriver to prevent it from rotating. (Clockwise)

  Lock nut tightening torque: 0.6 to 0.8 N·m

  Ensure that the lock nut is secured after adjusting the dispense volume.
