Use and maintenance of lotion pump

What is a lotion pump?

The lotion pump, also called a press-type lotion pump, is a liquid dispenser that uses the principle of atmospheric balance to pump out the liquid in the bottle by pressing and replenish the outside atmosphere into the bottle. Lotion pumps are mainly used in the packaging of toiletries, cosmetics, food and other products in our daily life.

The working principle of the lotion pump

Its working principle is to use a piston or diaphragm to generate a vacuum. When the pressure head of the lotion pump is pressed, the piston or diaphragm moves downward, compressing the air in the pump chamber to form a negative pressure. Under the action of negative pressure, the liquid in the bottle is sucked into the pump chamber through the straw. After releasing the pressure head, the piston or diaphragm returns to its position under the action of the spring, and the air in the pump chamber is re-sucked to discharge the liquid.

The structure of the lotion pump

The most typical lotion pump consists of: a head, a brace, a cylinder head, a cylinder, a piston rod, a piston, a piston head, a spring, a lower one-way valve, a gasket, and a hose. But not all lotion pumps must contain these parts. Depending on the specific performance requirements, some parts can be combined or replaced.
