Wholesale Top Quality 24/28MM Plastic Pump With Screw Lock for Lotion Cream Liquid

The spiral-lock emulsion pump is a specialized pump designed for conveying high-viscosity, high-stability emulsions. It is widely used in the cosmetics, pharmaceutical, food, and chemical industries. Its core features a spiral-locking structure (e.g., a screw, helical rotor, or a progressive cavity design) to ensure uniform and stable material delivery during conveying, preventing stratification or shear damage.

1. Structure and Operating Principle
The spiral-lock emulsion pump primarily consists of a helical rotor, stator, pump housing, and sealing system. During operation, the helical rotor rotates within the stator, forming a continuous, sealed cavity that propels material smoothly from the intake to the outlet. Its "spiral-lock" structure effectively prevents backflow and ensures precise and controllable flow, making it particularly suitable for high-viscosity or particulate-laden emulsions.

2. Product Features
Low-shear conveying: Gentle spiral propulsion minimizes damage to the emulsion structure, maintaining the stability of active ingredients.

High sealing: The spiral-locking design reduces the risk of leakage, making it suitable for handling expensive or sensitive materials (such as serums and ointments).

Strong self-priming capability: Can handle fluids with a wide range of viscosities (e.g., 1,000 to 100,000 cP), even semi-solid pastes.

Corrosion-resistant materials: The pump body is typically made of 316L stainless steel or PTFE-coated, compatible with acids, bases, and organic solvents.

Easy Cleaning and Maintenance: The modular design allows for quick disassembly and complies with GMP, FDA, and other hygiene standards.

3. Applications
Cosmetics: Filling and transferring products such as creams, lotions, and sunscreens.

Pharmaceutical: Closed-loop transfer of ointments, gels, and sterile emulsions.

Food: Processing of sauces, chocolate, and dairy products.

Chemical: Transfer of high-viscosity materials such as adhesives, resins, and greases.

4. Advantages
With high efficiency, stability, and hygiene as its core advantages, the screw-lock emulsion pump overcomes the shear damage and pulse fluctuations that plague traditional pumps (such as gear and centrifugal pumps) when transferring high-viscosity emulsions. It is an indispensable key piece of equipment in the fine chemical industry.
