How do Lotion Pumps work?
Step 1 - Synchronized with the principle of the suction device, it operates against gravity. When the head is pressed, the frictional force created by the inner wall causes the piston t to open.
Step 2 - When the actuator is depressed, the piston moves, which in turn compresses the spring. It exerts upward pressure inside the dip tube. Additionally, the material in the dip tube reaches the lotion pump chamber.
Step 3 - Once the actuator is released, the ball drops, stopping the flow of material, ensuring it does not return to the bottom of the lotion pump.
Step 4 - When the fluid in the body fluid storage chamber is full, press the head again to drain the fluid.
