Stainless Steel Screw Pump Specifications Stainless steel screw pumps are highly efficient, durable, and versatile positive displacement pumps designed for handling a wide range of fluids, including viscous, abrasive, and corrosive liquids. These pumps are widely used in industries such as food processing, chemical manufacturing, wastewater treatment, and oil and gas due to their robust construction and reliable performance. Below are the key specifications and features of stainless steel screw pumps: 1. Material Construction - Pump Housing: Made from high-grade stainless steel (e.g., SS304, SS316, or SS316L) for excellent corrosion resistance and durability. - Screw Rotors: Precision-machined from hardened stainless steel or coated with wear-resistant materials for long service life. - Shaft Seals: Options include mechanical seals, lip seals, or gland packing, depending on the application requirements. 2. Performance Specifications - Flow Rate: Ranges from 1 m³/h to 500 m³/h, depending on pump size and design. - Pressure Capacity: Typically operates between 6 bar and 24 bar, with high-pressure models available for specialized applications. - Viscosity Handling: Capable of pumping fluids with viscosities up to 100,000 cP or higher. - Temperature Range: Suitable for fluids from -20°C to 200°C, with optional heating/cooling jackets for extreme conditions. 3. Design Features - Self-Priming Capability: Can operate without manual priming, making them ideal for suction lift applications. - Low Pulsation Flow: Provides smooth, consistent fluid transfer, reducing vibration and wear. - Reversible Operation: Some models allow bidirectional flow for flexible system integration. - Modular Design: Easy disassembly for maintenance, cleaning, or rotor replacement. 4. Motor and Drive Options - Power Range: Motors from 0.37 kW to 75 kW, available in standard or explosion-proof configurations. - Speed Control: Compatible with variable frequency drives (VFDs) for precise flow adjustment. - Mounting Options: Horizontal or vertical installation to suit space constraints. 5. Applications - Food & Beverage: Hygienic transfer of syrups, creams, and pastes. - Chemical Processing: Handling acids, solvents, and aggressive media. - Marine & Offshore: Fuel transfer, bilge pumping, and ballast water management. - Wastewater Treatment: Sludge and effluent pumping in harsh environments. 6. Compliance & Certifications - Meets international standards such as ISO, ANSI, ATEX (for explosive environments), and FDA/USDA (for food-grade applications). 7. Maintenance & Service Life - Minimal maintenance required due to robust construction. - Seal and bearing replacements are straightforward, reducing downtime. Stainless steel screw pumps offer a reliable, low-maintenance solution for demanding fluid transfer applications. Their corrosion-resistant construction, high efficiency, and adaptability make them a preferred choice across multiple industries. For specific operational requirements, customization options are available to ensure optimal performance.
