how the pump works on soap dispensers

Pumps are used in different applications and usually found in household items for everyday usage. It is commonly used in sprayers and dispensers like soap dispensers. But how do pump dispenser pump works? How does it pump the liquid upwards?

The soap dispensers rely on the bottle and the air suction to draw the fluid upwards. The pump is attached to a long flexible plastic tube that runs through the bottom of the bottle. Above the dip is a valve that prevents the liquid from going back down to the tube.

The pump works by applying pressure on to the pump mechanism and then creates a suction effect which draws the liquid upwards the tube. Once you release the pump head, the valve returns to its sealing position to block the liquid from flowing back to the bottle.

A soap dispenser pump is composed of several components:

• The actuator is the top of the pump pressed to dispense the liquid soap.
• The closure is the part of the pump that is attached to the bottleneck.
• The outer gasket is made of plastic or rubber that prevents the liquid soap from leaking.
• A dip tube is a flexible tube that extends from the housing to the bottom of the container.
• Housing is the main component of the soap dispenser that draws fluid to the actuator.
