Ease of use at hand determines the quality of the Plastic Lotion Pump's components.
Closing: The assembly that screws the entire assembly onto the bottle neck. It is recognized as a common neck finish destination.

A shiny metal case is sometimes installed to improve its appearance.
Outer Gasket: The gasket is usually friction-fitted to the inside of the cap and acts as a gasket barrier in the mouth area to prevent product leakage. Depending on who the manufacturer of the product is, the outer gasket material is determined. Rubber and LDPE are two of the many options.

Housing: Usually made of polypropylene plastic, this assembly holds all pump components in place and acts as a transfer chamber that transfers product from the dip tube to the actuator and ultimately to the user's hand. The size of this enclosure depends on output and design.

Stem/Piston/Spring/Ball (internal components inside the housing): These parts will vary depending on the lotion pump design. When it comes to pump work, these little parts aren't all that small. In fact, for the proper functioning of products, it is important to use the highest quality standards in these products.

Dip Tube: A long plastic tube made of polypropylene plastic that extends the reach of the lotion pump to the bottom of the bottle. Depending on the bottle paired with the pump, the length of the dip tube will vary. A properly cut dip tube will maximize product usage and prevent clogging.
