How does the external spring design of External Spring Cleansing Oil Pump solve the leakage problem?

Principle of External Spring Design
The External Spring Cleansing Oil Pump adopts the structural design of the external spring, which is the key to its anti-leakage. Most traditional pump heads use internal springs. This design is prone to chemical reactions when the liquid contacts the spring metal, resulting in liquid leakage or contamination. The external spring design of the External Spring Cleansing Oil Pump places the spring component outside the liquid contact, fundamentally avoiding direct contact between the liquid and the metal spring.

Stability in high and low temperature environments
The External Spring Cleansing Oil Pump has good temperature adaptability, and its operating temperature range is -15℃ to 40℃. This wide temperature adaptability is achieved through the combination of external spring design and high-quality materials. Under temperatures, traditional spring pump heads may leak due to the expansion or contraction of the metal spring, while the external spring design effectively minimizes the impact of such temperature changes and ensures the stability of the pump head under different environmental conditions.

Food-grade materials and safety
External Spring Cleansing Oil Pump is made of food-grade raw materials, which not only improves the durability of the pump head, but also enhances the compatibility of the liquid. Food-grade materials have chemical stability and are compatible with many types of oily liquids without causing harmful reactions. In addition, these materials undergo strict safety testing during the production process to ensure that the liquid is not contaminated during contact. Compared with traditional materials, food-grade raw materials can effectively prevent the components in the liquid from chemically reacting with the pump head material, further reducing the risk of leakage.

Safety clip design and transportation protection
In order to ensure safety during transportation and use, External Spring Cleansing Oil Pump is also equipped with anti-drop and transportation safety clips. This design not only fixes the pump head assembly when the pump head is not in use to prevent accidental leakage or damage, but also effectively reduces the impact of external vibration on the pump head during transportation. The use of the safety clip greatly reduces the pump head failure caused by improper transportation, thereby improving the overall safety and reliability of the product.

Customization service and applicability
External Spring Cleansing Oil Pump provides bottle customization services, which allows the pump head to match different types of bottles according to customer needs. Through in-depth communication with customers, the pump head can be adjusted according to the specific design of the bottle, thus ensuring a fit between the pump head and the bottle mouth during use.
