1. Pump head diameter

28/410 specification: The 28/410 specification in EB-KP-003A/B/C Switch Pump refers to the pump head diameter of 28 mm, while "410" indicates its thread type. This specification is usually used for larger bottles and is suitable for products that require large flow or high viscosity liquids. For example, liquids such as shampoo, conditioner or detergent usually require a larger pump head so that the amount of liquid pumped each time is sufficient, thereby reducing the need for users to operate frequently. A larger pump head can release liquid more effectively and avoid liquid stuck at the pump head, thereby ensuring smooth flow of liquid. In addition, this specification of pump head design is also easy to control during use, which can meet the needs of fast use and large amount of liquid release, and improve the user experience.24/410 specification: Compared with 28/410, the pump head diameter of 24/410 specification is 24 mm, which makes it more suitable for smaller bottles. This specification is usually used for liquids such as cosmetics, skin care products or medicines, and users of these products usually need more precise dosage control. Smaller pump heads can provide smaller liquid release, reduce waste, and make the use of products more economical. In addition, the 24/410 pump head is also more suitable for matching with smaller bottles in design, making the overall packaging look more compact and delicate. This design makes the product more attractive in the market, especially in the field of high-end cosmetics and skin care products.

2. Applicable bottle mouth size
28/410 specification: This specification of pump head matches the bottle mouth with a diameter of 28 mm. The larger pump head design ensures that it is firmly installed on the bottle mouth and is not easy to loosen or leak. Bottles suitable for this specification usually have a larger opening to match the larger diameter pump head, which can ensure the smooth flow of liquid during use. For products that require a large amount of liquid release, such as household cleaners or shampoos, the large bottle mouth design can hold more liquid and provide a higher flow output. This specification of pump head can also provide more flexibility in bottle design, so that the product can meet the needs of users in both design and function.
24/410 Specification: The 24/410 pump head is designed for a 24 mm diameter bottle mouth, which is suitable for smaller bottles and containers. The small diameter pump head can be tightly fixed on the bottle mouth, preventing liquid leakage and ensuring that the amount of liquid pumped each time is accurate. For small-volume products such as cosmetics and skin care products, this specification can provide sufficient control to ensure that users can get the right amount of liquid they need each time they use it. This design not only meets the functional needs, but also provides a more refined effect visually, making the bottle look more in line with the standards of the high-end market. Bottles suitable for this specification usually also take into account the aesthetics of the product and the convenience of use for users.

3. Flow and Dosage
28/410 Specification: EB-KP-003A/B/C Switch Pump with a pump head diameter of 28 mm usually provides a larger flow rate. This pump head design allows more liquid to be released at each operation, making it particularly suitable for high-viscosity liquids or products that require a large amount of liquid. For example, products such as shampoo and shower gel often require more liquid to be pumped each time to meet the needs of users during bathing. A larger flow rate can reduce the number of user operations, thereby improving the efficiency of use. In addition, a large flow pump head can also effectively reduce the situation where the liquid is stuck at the pump head, ensuring the smooth release of the liquid. Another advantage of this pump head design is that it can adapt to a variety of different liquid types, including thicker viscous liquids.
24/410 specification: The relatively small 24 mm diameter pump head provides a lower flow rate, which makes it suitable for products that precisely control the amount of liquid released. Products such as skin care products, cosmetics, and medicines often require fine dosage to ensure that the amount of liquid used each time is just right. A small flow pump head can help users better control the amount of liquid used each time, reduce waste, and make the use of the product more economical. This pump head design is particularly suitable for scenarios that require precise measurement and high user experience, and can meet the needs of different users for product usage. The smaller flow rate also means that the pump head can be more compact in design, suitable for small bottles, and enhance the overall use experience of the product.

4. Design and appearance
28/410 specification: Due to the larger diameter of the pump head, the 28/410 specification pump head is more conspicuous in appearance. This design is usually paired with a larger bottle body, making the overall packaging look more stable and functional. The large pump head not only provides a sense of power visually, but also provides a better feel during operation. For large-capacity products, this pump head design can better meet the user's usage needs and enhance the product's market competitiveness. In addition, the 28/410 specification pump head can provide more design space, such as adding a customized logo or decoration on the pump head to meet the brand image and user's aesthetic needs.
24/410 specification: The 24 mm diameter pump head is relatively small and more delicate and detailed in design. This specification of pump head is usually used for small bottles or high-end products, making the bottle look more compact and elegant. Small pump heads can provide a sense of refinement visually, and also meet the requirements of the high-end cosmetics and skin care market. The smaller pump head design not only meets the market demand in terms of aesthetics, but also provides more precise dosage control in terms of function. Such a design makes the product more attractive to consumers when displayed, and can effectively enhance the product's market positioning and user experience.

5. Application scenarios
28/410 specification: Due to its large flow rate and design suitable for large bottle mouths, the 28/410 specification pump head is very suitable for products that require a large amount of liquid in household and industrial applications. Common applications include shampoo, shower gel, detergent, etc., which usually require more liquid to be pumped each time to meet the user's usage needs. In addition, this specification of pump head is also suitable for large-capacity industrial products such as liquid fertilizers, detergents, etc., and its design can provide fast and effective liquid release. It is suitable for production lines, large supermarkets and daily household use to provide a convenient and efficient way of distributing liquids.
24/410 specification: This specification of pump head is widely used in the fields of cosmetics, skin care products and pharmaceuticals, which usually require precise dosage control. Skin creams, lotions, essences and other products usually use 24/410 specification pump heads to ensure the accuracy of the amount of liquid each time they are used, so as to meet the needs of users. In addition, this specification of pump head is also suitable for high-end markets and professional applications, providing a refined and efficient use experience. For the beauty and pharmaceutical industries, this design can ensure the stable release of liquids and can adapt to the design requirements of different bottles, thereby improving the overall value of the product and user satisfaction.
