Spiral emulsion pumps are efficient and stable fluid conveying equipment widely used in the chemical, pharmaceutical, food, and cosmetics industries. They are particularly well-suited for conveying high-viscosity, particulate-containing, or shear-sensitive materials. Their core features are as follows:
1. High-Efficiency Conveying Capacity
Spiral emulsion pumps utilize a helical rotor or screw structure, enabling continuous and smooth fluid conveying. They are particularly suitable for conveying high-viscosity emulsions, pastes, and other media. Their unique spiral propulsion mechanism effectively reduces pulsation, ensuring uniform flow and improving production efficiency.
2. Low-Shear, Gentle Conveying
Compared to centrifugal or gear pumps, spiral emulsion pumps operate at lower speeds, exerting less shear on the material, thereby maximizing emulsion stability and avoiding damage to sensitive ingredients (such as polymers and emulsifying systems). They are suitable for applications such as cosmetics and pharmaceuticals, where material integrity is paramount.
3. Strong Self-Priming Capacity and High Output Pressure
Spiral pumps offer excellent self-priming properties, enabling rapid aspiration even with unstable feeds, reducing the risk of dry running. Furthermore, its closed spiral structure generates high output pressure, making it suitable for conveying over long distances or under high-resistance conditions.
4. Wear-Resistant and Corrosion-Resistant Design
The pump body is typically made of stainless steel (such as 304 or 316L) or specialized engineering plastics, offering both corrosion and wear resistance. It can handle particulate-laden, acidic, or alkaline emulsions, extending the life of the equipment.
5. Easy Maintenance and Cleaning
The modular design simplifies disassembly and assembly, meeting CIP (Cleaning-in-Place) and SIP (Sterilization-in-Place) requirements, satisfying the high hygiene standards of industries such as food and pharmaceuticals. Some models also feature a dead-angle flow path design to prevent residue buildup.
6. Energy-Saving and Environmentally Friendly
Screw pumps offer high efficiency and lower energy consumption than traditional pumps. Their low-leakage design reduces material waste and production costs, aligning with the trend toward green manufacturing.
7. Wide Applicability
In addition to emulsions, these pumps can also be used to convey high-viscosity fluids such as colloids, slurries, and oils, meeting the process requirements of diverse industries, such as paint, asphalt, and cosmetic creams.
Summary: With its high efficiency, low shear, corrosion resistance, and easy maintenance, spiral emulsion pumps are an ideal choice for demanding fluid transfer applications, especially in areas where material property protection and production hygiene are critical.
