N Single Screw Pump with Feeder: Technical Overview The N Single Screw Pump with Feeder is a highly efficient and versatile positive displacement pump designed for handling viscous, abrasive, or shear-sensitive fluids across various industries. Its robust construction, precise metering capabilities, and reliable performance make it ideal for applications in food processing, wastewater treatment, chemical manufacturing, and oil and gas. Design and Working Principle The pump consists of a single helical rotor (screw) rotating within a double-threaded stator made of elastomeric material. As the rotor turns, it creates sealed cavities that progress along the stator, transporting fluid from the suction to the discharge port with minimal pulsation. The integrated feeder ensures consistent material intake, preventing dry running and optimizing efficiency, especially for thick or non-flowing media. Key Features 1. High Viscosity Handling – Capable of pumping fluids ranging from low to extremely high viscosities (up to 1,000,000 cP). 2. Gentle Product Handling – Low shear operation preserves fluid integrity, making it suitable for sensitive materials like creams, slurries, or polymers. 3. Self-Priming & Dry-Run Resistance – The feeder-assisted design enhances suction performance, even with semi-solids or air-entrained fluids. 4. Precise Metering – Delivers accurate flow rates (±1% repeatability), ideal for dosing or batching processes. 5. Abrasion Resistance – Stator materials (e.g., NBR, EPDM, or PTFE) and hardened rotor coatings extend service life in abrasive applications. 6. Low Maintenance – Simple construction with minimal wearing parts reduces downtime. Applications - Food & Beverage: Transferring syrups, chocolate, pastes, or dairy products. - Wastewater/Sludge: Handling thickened sludge, lime slurry, or dewatering processes. - Chemicals: Metering adhesives, resins, or corrosive fluids. - Oil & Gas: Pumping crude oil, drilling mud, or viscous hydrocarbons. Operational Advantages - Energy Efficiency: The progressive cavity design minimizes internal slip, reducing power consumption. - Variable Speed Compatibility: Works seamlessly with frequency drives for adjustable flow control. - Compact Footprint: Modular feeder integration saves space in constrained installations. Conclusion The N Single Screw Pump with Feeder combines mechanical simplicity with advanced functionality, ensuring reliable fluid transfer in demanding environments. Its adaptability to diverse materials and operational conditions makes it a preferred choice for industries prioritizing precision, durability, and process efficiency. (Word count: 500)
