Pump Components and Materials
Main Components
Lotion pumps consist of several components, each playing a crucial role in the pump's functionality. The main components are typically made of PE, PP, or LDPE, which are durable and compatible with most cosmetic formulas.
These components can be decorated using various processes to enhance the pump's appearance and align with your brand's aesthetic. Some common decoration techniques include:
Electroplating: Applying a thin layer of metal, such as silver or gold, to create a luxurious finish
Printing: Adding logos, text, or designs using silk-screening, pad printing, or heat transfer methods
Hot Stamping: Pressing a metallic foil onto the surface to create a glossy, eye-catching effect
Dip Tube Design
The dip tube is the component that extends from the bottom of the pump into the container, drawing the product up into the pump mechanism. Designing the right dip tube is essential for ensuring optimal product dispensing and minimizing waste.
When considering dip tube length, keep the following in mind:
Optimal length: The tube should reach the bottom of the container without bending or coiling. It should leave a small gap (about 1-2mm) to prevent blockage.
Avoiding tube bending: A bent tube can lead to incomplete product dispensing and increased product waste. Ensure the tube is cut to the appropriate length and fits securely into the pump mechanism.
Cutting angles: The end of the dip tube should be cut at an angle rather than straight across. This angled cut helps prevent the tube from suctioning to the bottom of the container, ensuring a consistent product flow.
In addition to length, the dip tube's diameter and material should be considered based on your product's viscosity. Thicker formulas may require a wider tube to facilitate smooth dispensing, while thinner liquids can work well with narrower tubes.
Factors to Consider When Choosing a Lotion Pump
Compatibility with Raw Materials
When selecting a lotion pump, it's crucial to consider the compatibility between the pump materials and your product's raw materials. Most pump components are made of PP, PE, or LDPE, which are generally compatible with a wide range of cosmetic ingredients.
However, certain strong acids, alkalis, organic solvents, or fragrances may react with these materials, leading to degradation or changes in the pump's properties. To ensure optimal performance and product integrity, it's essential to conduct compatibility tests between your product and the chosen lotion pump.
Pumping Volume
Choosing the right pumping volume is key to providing a pleasant user experience and ensuring your product lasts as intended. Low viscosity materials like toners and serums typically require a smaller dosage per pump, around 0.5ml to 1.0ml. On the other hand, high viscosity products like creams and gels may need a larger dosage, ranging from 1.0ml to 2.0ml per pump.
Consider the following examples:
For a 100ml bottle of serum, a 0.5ml pump delivering 200 doses may be ideal
A 500ml bottle of lotion might benefit from a 2.0ml pump, providing 250 doses
Packaging Type and Capacity
The packaging type and capacity of your product will also influence your choice of lotion pump. Consider the expected usage frequency and the amount of product needed per application.
For instance:
Neck Finish Specifications
Lotion pumps come in various neck sizes to fit different bottle neck finishes. Common neck sizes include:
18mm
20mm
22mm
24mm
28mm
33mm
38mm
It's important to choose a pump with a neck size that matches your bottle's neck finish to ensure a secure fit and prevent leakage. Some common neck finish standards are:

Viscosity and Liquidity of the Product
The viscosity and liquidity of your product will also play a role in selecting the appropriate lotion pump. Here's a simple test to determine your product's viscosity:
Pour the liquid into a beaker and observe how quickly it levels:
Instant leveling with no traces: any lotion pump will work
Slight traces of stacking: most pumps will work, but spray pumps may need testing
Obvious traces of mounding: use pumps with high suction power and spring elasticity, like high viscosity pumps
Mounding without leveling: high viscosity pumps may need testing, consider airless pumps or alternative packaging
Inversion test for high viscosity:

Design and User Experience
Pump Closure Mechanisms
Lotion pumps come with various closure mechanisms that not only provide a satisfying user experience but also help preserve the product's integrity. The three main types of closure mechanisms are:
Lock up: This is the most popular and aesthetically pleasing option. The pump dispenses the product immediately when pressed and returns to its original position when released. Some lock up pumps can be securely locked with a twisting motion.
Lock down: This mechanism sits higher from the neck base and must be unlocked before dispensing. After use, the pump needs to be pressed down again to lock it securely.
Clip lock: Available in various styles, clip lock pumps feature a plastic clip attached to the neck. This clip serves as a tamper-evident feature and also provides child safety.
Each mechanism has its own benefits, such as preventing leakage during transportation, maintaining product freshness, and enhancing the overall user experience.
Rebound Performance
A lotion pump's rebound performance refers to its ability to return to its original position after being pressed. This is crucial for preventing product leakage and ensuring a clean, mess-free dispensing experience.
To test a pump's rebound performance, press it down firmly and release, then observe how long it takes to fully return to its starting position. The optimal rebound time is generally within 3 seconds.
A pump with poor rebound performance may lead to product accumulation around the nozzle, which can cause clogs and an unsightly appearance.
External vs. Internal Spring Pumps
Lotion pumps can be categorized based on the location of their spring mechanism: external or internal.
External spring pumps have their spring visible on the outside of the pump body. This design prevents the spring from coming into direct contact with the product, making it a hygienic and durable option. External spring pumps are suitable for high-viscosity products like creams and gels.
Internal spring pumps, on the other hand, have their spring located inside the pump body. While this design is more aesthetically pleasing, the spring may come into contact with the product. Internal spring pumps are best suited for low-viscosity liquids like toners and serums.
Innovative Designs
As the cosmetics industry evolves, so does the demand for innovative packaging designs. Unique and eye-catching lotion pumps can help your product stand out on the shelf and attract consumers' attention.
However, it's essential to strike a balance between creativity and functionality. An overly complex or unconventional design may compromise the pump's performance and frustrate users.
When considering innovative designs, always prioritize user experience. Ensure that the pump is intuitive to use, dispenses the product effectively, and is compatible with your product's viscosity and other characteristics. For certain products, you might want to consider the difference between regular pumps and airless pumps to determine which best suits your needs.
Performance and Quality Testing
To ensure your lotion pumps meet the highest standards of performance and durability, it's crucial to conduct thorough quality checks. These tests help identify potential issues and ensure your pumps can withstand the rigors of real-world use. For a comprehensive understanding of cosmetic packaging testing, including lotion pumps, you can refer to our detailed guide.
Here are five essential quality checks to consider:
Drop Test: This test simulates accidental drops during normal use. The pump is dropped from a height of 1.2 to 1.5 meters onto a hard surface, typically 3-5 times. After the drops, the pump should remain intact and functional, with no signs of cracking or breaking.
Transportation Test: To evaluate the pump's ability to withstand the stresses of transportation, it's subjected to simulated vibrations and jolts. This test helps ensure the pump arrives at its destination in perfect condition, ready for use.
Thermal Endurance Test: Lotion pumps should be able to withstand temperature fluctuations without compromising their performance. During this test, pumps are exposed to extreme temperatures (typically -15°C to +45°C) for extended periods. They should function normally after returning to room temperature.
Fatigue Test: This test assesses the pump's durability over repeated use. The pump is subjected to a specified number of actuation cycles (usually 5,000 to 10,000) to simulate long-term use. The pump should remain fully functional and maintain its rebound performance throughout the test.
Leakage Test: A pump's ability to prevent leakage is paramount. This test involves filling the container with the product, attaching the pump, and subjecting it to various conditions (such as high pressure, high temperature, or inversion) to check for any signs of leakage.
| Test | Purpose | Procedure |
| Drop Test | Simulate accidental drops | Drop from 1.2-1.5m height, 3-5 times |
| Transportation Test | Evaluate resistance to transportation stress | Subject to simulated vibrations and jolts |
| Thermal Endurance | Assess performance under temperature changes | Expose to extreme temperatures (-15°C to +45°C) for extended periods |
