If you sell products like this, the article you’re about to read will help you understand your products better. You’ll also be more able to help your customers in case they have any questions or troubleshooting issues. 

Identify the Parts of a Bottle Pump Dispenser

To help us better illustrate the purpose of bottle pumps, we’ll use a soap dispenser as an example. We’ll go over the various components that work together to provide a specific amount of liquid. Here are some of the components:

Closure: This is the part of the pump that is fastened to the bottleneck, which often features a smooth or ribbed texture. 

Actuator: The actuator is also known as the pump head, and it is the part of the dispenser that dispenses the actual liquid. 

Outer Gasket: This part fits inside and tends to be made of rubber or plastic. It’s responsible for decreasing the chance of the product leaking. 

Housing: This is considered the main pump assembly, and it helps to keep pump constituents in the correct position. It then feeds fluid into the actuator. 

Dip Tube: This tube is often easily visible and it goes from the housing, which is at the bottom of the container, and it carries the liquid up into the dispenser. 

Interior Components: There are several constituents, including a piston, ball, spring, and stem, which is what moves the liquid from the dispenser into the actuator. 

Understanding these various components will help you better identify problems and also make you a wiser shopper. If you work in the liquid soap industry, understanding these components will be crucial to sourcing the highest quality bottle pumps and dispensers.  

How Soap Dispensing Bottle Pumps Work

The components inside the bottle combined with the air suction that helps to draw the liquid upwards against gravity. 

Every time that you push the actuator, there’s a piston that places pressure on the inside spring which then moves the ball upward, and it takes some of the liquid with it. 

Once you release the actuator, the spring and piston will go back to their original resting positions. This will seal the housing chamber and prevent fluid from going back up through the bottle.
