Lotion pumps, one of the most popular dispensing methods for viscous (thick liquid) products in the personal care and beauty industry, come in all shapes and sizes. When used as designed, pumps dispense the right amount of product time after time. But have you ever wondered what goes in a lotion pump to makes it work? While there are hundreds of different designs in the market today, the basic principle is the same.
Generally speaking, a lotion pump consists of the following components :
Actuator : An actuator, or the pump head, is what the consumer presses down to pump the product out of the container. The actuator is often made of PP plastic and can have many different designs - and often come with a up-lock or down-lock features to prevent accidental output. This is one of the component designs that can set one pump apart from another when it comes to the exterior design, it is also the part where ergonomics play a role in consumer satisfaction.
Closure: The component that screws the entire assembly onto the neck finish of the bottle. Often made of PP plastic, it is often designed with a rib side or smooth side surface. In certain cases a shiny metal overshell can be installed to give the lotion pump a high-end, elegant look.
Outer Gasket: The gasket is often friction fitted to the inside of the closure and it acts as a gasket barrier on the bottle land area to prevent product leakage. This outer gasket can be made from a wide variety of materials depending on the manufacturer's design: Rubber, LDPE are just two of the many possible options.
Stem / Piston / Spring / Ball (Interior components inside the housing) : These are the parts that can vary based on the design of the lotion pump. Some may even have additional components that aid the product flow, and some designs may even have additional housing components that isolate the metal spring from the product pathway, these pumps are generally referred to have a "metal free pathway" feature, where the product will not come in contact with the metal spring - eliminating the potential compatibility problems with the metal spring.
Dip Tube: a long plastic tube made of PP plastic that extends the reach of the lotion pump to the bottom of the bottle. Depending on the bottle the pump is paired with, the dip tube length will differ.
