I. Key Features
1. Efficient and Stable Conveying
Steady, Pulsation-Free Flow: Utilizes a sealed cavity structure formed by an eccentric screw and a stator; the medium is propelled axially and uniformly at low internal flow velocities, ensuring stable output pressure (single-stage pressure: 1.2 MPa; head: 120 m).
Wide-Range Flow Regulation: Flow rate is directly proportional to rotational speed (0–150 m³/h); supports stepless speed regulation or variable frequency control to meet diverse operating requirements.
2. Excellent Medium Adaptability
Handling High-Viscosity and Solids-Laden Media: Capable of conveying fluids with viscosities up to 100,000 cP; compatible with media containing solid particles (particle size ≤ 0.2 mm), fibers, or corrosive substances (e.g., acids, alkalis, chemical raw materials).
High Temperature Resistance: Standard models operate between -15°C and 80°C; specially designed versions can withstand up to 350°C, meeting high-temperature application needs.
3. Strong Self-Priming and Flexible Installation
Self-Priming Lift up to 6 Meters: No priming water required; enables quick startup—ideal for deep-well or low-level liquid extraction.
Multi-Directional Installation: Supports horizontal, vertical, or inclined installation, offering exceptional spatial adaptability.
4. Energy Efficiency, Environmental Friendliness, and Low Maintenance
High Efficiency and Energy Saving: Volumetric efficiency >90%; energy consumption is 30% lower than centrifugal pumps; operating noise <65 dB.
Modular Design: Minimal components (only the rotor and stator are core wear parts); disassembly and assembly require no special tools, resulting in low maintenance costs.
II. Technical Advantages
1. Structural Design
Dual-Material Stator: An elastic rubber or polyurethane stator paired with a metal screw balances wear resistance and sealing performance, extending service life by 50%.
Compact and Lightweight: 20% smaller in volume than comparable pumps; lightweight design facilitates easy relocation or integration into existing systems.
2. Smart Upgrade Options
Intelligent Control: Optional sensors and IoT modules enable real-time monitoring of flow, pressure, and equipment status, as well as remote control and adjustment. Bi-directional Pumping Capability: Reversing the stator rotation enables reverse flow, allowing a single pump to serve multiple purposes.
III. Typical Application Scenarios
Chemical/Petroleum: Transporting high-viscosity or corrosive media such as polymers, crude oil, and catalysts.
Environmental Protection/Wastewater: Handling wastewater containing sludge and suspended solids; compatible with a pH range of 2–12.
Food/Pharmaceutical: Sanitary design compliant with GMP standards; suitable for syrups, jams, medicinal liquids, etc.
Paper/Metallurgy: Transporting high-solids-content fluids like pulp and mineral slurry without shear damage.
IV. Selection and Maintenance Recommendations
Parameter Matching: Select stator materials (e.g., wear-resistant rubber or food-grade silicone) based on medium viscosity and particle content.
Maintenance Cycle: Inspect stator wear every 500 hours and regularly replace mechanical seal oil (reduce interval to 300 hours for high-temperature operations).
With its unique sealed cavity design, broad media compatibility, and low-maintenance nature, the Suda G-series screw pump stands as a benchmark product in industrial fluid handling. Options for intelligent upgrades further enhance its competitiveness in modern production environments. Users should prioritize medium characteristics and temperature ranges during selection to maximize equipment performance.
