How Does the HLX Series Screw Pump Drive the Future of Industrial Fluid Conveyance with “Spiral Power”?

In the vascular network of modern industrial production, fluid transfer pumps play a crucial role. However, when faced with complex, high-viscosity, high-solid-content, or even highly corrosive fluid media, traditional centrifugal or piston pumps often struggle. Their limitations can lead to low conveying efficiency, severe equipment wear, or even medium contamination—undoubtedly pain points urgently needing solutions in industrial production. Against this backdrop, a unique fluid conveyance solution has emerged: the HLX series screw pump, renowned for its “spiral power.”

The core secret of this pump lies in its unique internal structure and working principle. Through the rotation of one or more spiral blades inside the casing, a continuous, positive-displacement conveying chamber is formed, pushing fluids forward in a gentle, stable, and efficient manner. Unlike centrifugal pumps that generate centrifugal force through high-speed rotation, it forces media conveyance through volume changes. Thus, regardless of the medium’s viscosity or the number of solid particles it contains, the pump can achieve precise conveyance with an almost constant flow rate. This exceptional performance allows the HLX series screw pump to stand out in various industrial applications, becoming a key tool for solving complex fluid conveyance challenges.

Key to Industrial Sectors: Wide Applications of HLX Series High-Viscosity Screw Pumps

The powerful capabilities of the HLX series screw pump are fully demonstrated in various high-viscosity fluid conveyance scenarios.

• Chemical industry: Widely used to convey polymer melts, resins, emulsions, paints, and various viscous chemical slurries. These media are often sensitive to shear forces; the high-speed rotation of traditional pumps would destroy their molecular structures, while the low-shear conveying characteristics of screw pumps perfectly preserve the original properties of the media.

• Food industry: Takes on the task of conveying chocolate paste, honey, jam, tomato sauce, and various concentrated fruit juices. These food-grade media not only require the pump to have high-viscosity conveying capabilities but also demand strict hygiene standards. The smooth conveyance of the HLX series screw pump avoids bubble formation or emulsification caused by violent stirring, ensuring product quality and taste.

• Pharmaceutical industry: Used to convey high-viscosity, high-purity materials such as ointments, syrups, and biological agents. Its stable and controllable flow rate ensures precision and safety in the production process.

• Other fields: Also indispensable in sewage treatment, papermaking, and building materials industries—for example, conveying sludge, pulp, and cement slurry—demonstrating its strong versatility and reliability. The wide application of the HLX series screw pump fully proves that it has become an indispensable key technology in modern industrial fluid conveyance.

Screw Pump Selection Guide: How to Find the Right HLX Series Pump for Your Industrial Process?

Selecting a suitable HLX series screw pump for a specific industrial process is more than just choosing a model; it requires comprehensive consideration of multiple factors.

1. Understand medium properties: Detailedly analyze the physical and chemical characteristics of the conveyed medium, including viscosity, temperature, density, corrosiveness, abrasiveness, and whether it contains solid particles. For example, when conveying highly abrasive media, wear-resistant rotor and stator materials should be selected; for corrosive media, special corrosion-resistant alloys or coatings are necessary.

2. Define flow rate and head requirements: The flow rate of the HLX series screw pump is proportional to its rotational speed, so precise control can be achieved by adjusting the speed according to process needs. The head must consider factors such as conveying distance and pipeline resistance to ensure the pump has sufficient pressure to deliver the medium to the designated location.

3. Choose appropriate materials: The HLX series screw pump offers diverse component materials, from stainless steel and carbon steel to various corrosion-resistant alloys and even non-metallic materials. Each material has its specific application range. Selecting the right material not only affects the pump’s service life but also directly impacts medium purity and safety.

4. Consider sealing and drive modes: Mechanical seals are suitable for most applications, but for special media, packing seals or magnetic drives may be required. The choice of drive mode depends on on-site power supply conditions and control requirements, with common options including direct motor drive or reducer-equipped drive.

A scientific and rigorous selection process is the foundation for ensuring the screw pump operates efficiently, reliably, and long-term.

Precision and Hygiene in Balance: Design Philosophy of HLX Series Food-Grade Screw Pumps

In industries with extremely high hygiene standards—such as food, beverage, pharmaceuticals, and cosmetics—the design philosophy of fluid conveyance equipment differs significantly from ordinary industrial applications. The design of the HLX series food-grade screw pump exemplifies the perfect integration of “precision” and “hygiene,” two seemingly contradictory concepts.

• Cleanable, dead-angle-free structure: The internal pump body undergoes fine polishing, with all medium-contacting surfaces achieving extremely high surface finish to eliminate the possibility of bacterial growth and dirt residue. Meanwhile, the pump is easy to disassemble and assemble, facilitating thorough CIP (Clean-in-Place) or SIP (Sterilization-in-Place) to ensure sterility in each use.

• Strict material selection: All material-contacting components—rotors, stators, seals, etc.—use materials compliant with international standards such as FDA (U.S. Food and Drug Administration) or EHEDG (European Hygienic Engineering & Design Group), such as 316L stainless steel or dedicated food-grade elastomers. These materials are not only corrosion-resistant, non-toxic, and odorless but also do not react with media, ensuring the purity and safety of conveyed materials.

• Gentle, low-shear conveyance: This avoids emulsification or bubble formation in materials while protecting their physical properties—critical for maintaining the quality of food, dairy products, or biological agents.

This philosophy, combining rigorous engineering design with high hygiene standards, makes the HLX series food-grade screw pump a reliable choice for ensuring product quality and consumer safety.

Coping with Harsh Environments: Necessity of Customized HLX Series Corrosion-Resistant Screw Pumps

In fields such as chemical engineering, metallurgy, and environmental protection, the corrosiveness of fluid media is one of the biggest challenges for equipment. Media like strong acids, alkalis, high-salt solutions, or organic solvents can severely erode metal pump components, not only shortening equipment life but also potentially causing serious safety accidents and environmental pollution due to leakage. Thus, customized corrosion-resistant screw pumps are particularly important for these harsh applications.

The HLX series screw pump’s customization service is designed to meet this demand:

• Material customization: Based on the medium’s chemical composition, concentration, and temperature, the most suitable corrosion-resistant materials are selected for core components. For example, high-nickel-chromium alloys, titanium alloys, or non-metallic materials like PTFE may be used for strong acids such as sulfuric acid and hydrochloric acid; stainless steel or special engineering plastics may be chosen for strong alkalis.

• Seal structure optimization: Corrosive media are particularly destructive to seals, so double mechanical seals or special sealant flushing schemes may be adopted to ensure reliable and long-lasting sealing.

• Wear resistance enhancement: For abrasive corrosive media, rotor surfaces can be treated with hard alloy spraying or ceramic coatings to improve wear and corrosion resistance.

This in-depth customization based on specific working conditions not only significantly extends the screw pump’s service life in harsh environments, reducing maintenance costs and downtime but, more importantly, fundamentally ensures the safety and stability of production processes, creating long-term value for enterprises.
