Six Things You Probably Do Not Know About Lotion Pumps

Plastic lotion pumps are widely used for dispensing viscous fluids, such as liquid soap, hand sanitizer, and face wash, to name a few. Although there’s a plethora of polypropylene-made lotion pumps available these days in the market, their fundamental working mechanism remains the same.

In this blog, we’ll briefly cover the major parts of a regular lotion pump and how they function.

Key Components of a Lotion Pump

Standard lotion pumps usually have 6 parts.

  • Actuator – Made of polypropylene and also called the pump head, its primary task is to expel the content from the lotion pump reservoir when being pressed.
  • Closure – The entire assembly is secured onto the neck of the lotion pump with the help of this component.
  • Outer Gasket – Generally made of low-density polyethylene or rubber, it helps prevent leakage of content from the bottle land area and is usually friction-fitted inside the closure.
  • Housing – Also known as pump assembly housing at times, it keeps all the parts of the lotion pump in one place. The lotion pump housing also doubles up as a transfer vessel for sending the content to the actuator from the dip tube.
  • Internal Housing Components (Ball/Spring/Piston/Stem) – The inner housing parts of the lotion pump are dependent on the respective product design and differ from one manufacturer to another.
  • Dip Tube – It’s a long tube made of polypropylene that extends from the nozzle of the lotion pump to its extreme bottom.


Working Principle of a Lotion Pump

  • Step 1 – The functioning of a lotion pump is analogous to that of air suction equipment. It acts against gravity and helps the content inside the tank reach user’s palm.
  • Step 2 – When the actuator is depressed, the piston is shifted, which, in turn, compresses the spring. It effectively allows the air pressure exerting upwards to draw the ball in an upward direction along with the content inside the dip tube. The content fills the dip tube first and then reaches the lotion pump chamber.
  • Step 3 – As soon as the actuator is released, the spring relocates to its original position. The ball goes back to its standby position and seals the tank, shutting down the flow of content so that it cannot return to the lotion pump bottle.
  • Step 4 – The three steps above are collectively known as priming. When the actuator is pressed once again from its resting position, the reservoir content will first traverse through the stem and then reach the actuator. Finally, the pump dispenses the liquid onto the user’s hand.

Six Essential Things to Consider When Purchasing Lotion Pumps in Bulk Online

There’re lots of things that need to be checked before buying lotion pumps online. The material, neck size, price are just a few of the many.

Lotion dispensing pumps are manufactured for dispensing a range of liquids; this includes hand creams, soaps, and body washes. Products contained in lotion pump dispensers happen to be increasingly appealing and more preferred by consumers. Furthermore, these are easy to use and lasts long.
Lotion pumps function as lock-down or lock-up devices. While the former is mostly used in spas, leisure centers, gymnasiums, and hotels, the latter type is primarily used to dispense common household fluids.

If you intend to shop for lotion pumps in bulk online anytime soon, you must consider the following six factors before proceeding with your purchase.

Material Composition

The durability of a lotion pump depends on the composition of its material. Besides polypropylene, you can also opt for glass, steel, ceramic, and other premium or exotic materials.
Before placing an online bulk order for lotion pumps, you should finalize in the first place where you want to use them. For instance, steel and ceramic are best suited for residential homes and private settings due to their longevity and aesthetics.
If you want to keep them in a commercial environment, steel is preferred over other materials for its sheer durability. On the contrary, go for glass-made lotion pumps for that boutique feel, which are not only lightweight but highly affordable as well.

Neck Size

You should decide the neck size of the lotion pumps you need in bulk. 24/415, 24/410, and 20/210 are the most common lotion pumps are available. The sizes, as mentioned earlier, are compatible with a range of lotions pumps! Selecting a proper neck size is necessary for creating the right dispenser-bottle combination.

Tube Length

Make sure to examine the tube length thoroughly. The plastic tube fitted inside these pumps can be appropriately shortened for matching its chamber volume. Its tube radius should also be suitably large to accommodate liquids of desired viscosity. So, you should always remember to choose wisely and carefully.

Pump Capacity

2.0 ml, 1.4 ml, 0.28 ml, and 0.5 ml are some of the standard volumes that the present-day lotion pumps can accommodate. You should select your lotion pumps’ capacity as per product specifications, bottle dosage, product cost, and expected use.


As the  lotion pumps are usually made of plastic, check whether the color of the pump is in sync with the liquid. You’ll have a range of options while choosing online. Furthermore, these pumps are often coated with a shining aluminum film, which offers a compelling look and provides the perception of being a luxury good. Ensure that the combination of the film and plastic is looking good with the liquid.


The quality of the packaging is as important as the articles that you market. Having excellent stuff in lousy packaging does not help in getting business. If you require high-quality lotion pumps, you should be prepared to shell out more. However, as a matter of fact, the long-term benefits are immense.


When it comes to buying lotions pumps in bulk online, you should always remember to consider the neck size, material composition, pump capacity, available colors, tube length, and of course, the selling price.
