Threaded pumps are widely used in the cosmetics, cosmetics, and pharmaceutical industries. They attach to the bottle neck via a threaded locking mechanism and utilize a push-type piston mechanism for precise and hygienic liquid dispensing. Their key features are as follows:
1. Precise and metered delivery
A precision piston and valve design ensures consistent delivery of liquid (e.g., 0.2mL, 0.5mL, 1.0mL, etc.) with each press, minimizing waste. These pumps are particularly suitable for high-value liquids (e.g., serums and medicinal solutions).
Customizable dosage sizes meet diverse production needs.
2. Highly airtight and leak-proof design
The threaded locking mechanism (e.g., standard 28/410 and 24/410 sizes) securely fits the bottle neck, preventing leakage or evaporation.
Built-in silicone seals or double valves prevent air backflow, extending the shelf life of the contents.
3. Wide compatibility with a wide range of liquids
These pumps can deliver liquids of varying viscosities, including aqueous, emulsions, and gels (viscosities ranging from 1 to 50,000 cP).
Special models support multi-function conversions, such as foam pumps and spray pumps.
4. Convenient Operation and Excellent User Experience
One-handed press and dispense ensures smooth, residue-free dispensing.
Some models feature a 360° swivel pump head for easy use at various angles.
5. Safety and Hygiene
Material materials comply with FDA, EU, and other international standards (such as PP, PE, and stainless steel), ensuring they are non-toxic and pollution-free.
Optional child safety lock prevents accidental operation.
CIP cleaning compatible, meeting pharmaceutical and food-grade hygiene requirements.
6. Durability and Environmental Protection
The spring and piston are made of corrosion-resistant materials (such as 304 stainless steel) with a lifespan of over 10,000 pump cycles.
The removable structure allows for refilling of the bottle, reducing packaging waste.
Summary: With its core advantages of precise dosing, leak-proof sealing, safety and hygiene, threaded pumps have become an efficient solution in the field of liquid packaging, especially suitable for industries with strict requirements on dosage control and product preservation.
