How Does The Shampoo Lotion Pump Work?

When you push the actuator, the piston moves to compress the spring, and the upward air pressure pulls the ball, along with the product inside, up into the dip tube and then into the chamber. When the user depresses the actuator , the spring brings the piston and the actuator back to their up positions , and the ball returns to its resting position , sealing the chamber and preventing the liquid product from flowing back into the bottle . " Priming " refers to the first cycle . When the user presses the actuator again , the product in the chamber is taken from the chamber , through the stem and actuator , and distributed out of the pump and on your hand .
