3.5 - 4.0 ML discharge rate Lotion pump 28/410 33/410 38/400 38/410 White color XY12-2

Features:

When we press the actuator for the first time, we press the actuator through the connected stem to

drive the sub-stem to compress the spring together. In the process of compressing spring, the outer

wall of the piston is rubbed with the inner cavity wall of the body, which urges the piston to open the

discharge hole of the sub-stem. When the piston slides down, the air in the body is discharged through

the opened sub-stem discharge hole. Press back and forth many times to vent all the air in the housing.

After the air in the housing is discharged by pressing the actuator through the stem, sub-stem, the piston

and the common compression spring, the actuator is loosened and the spring moves upward because

of the loss of pressure, and the piston also moves down through the inner wall of the friction body.

Close the discharge hole in the sub-stem. At this time, the liquid storage cavity of the body forms a

vacuum suction state, the glass ball is sucked up, and the liquid in the bottle is sucked into the liquid

storage cavity of the housing through the tube.

When the liquid in the bulk storage chamber is full, press the actuator again and the liquid will flow out

directly from the nozzle through the outlet hole.
