G-Type All-Stainless Steel Screw Pump: Technical Overview The G-Type All-Stainless Steel Screw Pump is a highly efficient and durable positive displacement pump designed for handling viscous, abrasive, or corrosive fluids in demanding industrial applications. Its robust construction, precision engineering, and versatile performance make it a preferred choice for industries such as food processing, chemical manufacturing, wastewater treatment, and oil & gas. Design & Construction The pump features an all-stainless-steel (SS) body, including the housing, rotor, and stator, ensuring exceptional resistance to corrosion, high temperatures, and mechanical wear. The use of AISI 304 or 316 stainless steel enhances durability in harsh environments, while polished surfaces minimize contamination risks in hygienic applications. The single-screw (progressive cavity) design consists of a helical rotor rotating within a double-threaded stator, creating a series of sealed cavities that move fluid smoothly with minimal pulsation. This design ensures low shear, gentle handling, making it ideal for shear-sensitive or viscous media like slurries, pastes, and polymers. Performance Features - Self-Priming & High Suction Lift: Capable of dry-running for short periods and handling fluids with entrained gases or solids. - Precise Flow Control: Delivers a consistent, pulse-free flow rate proportional to speed, enabling accurate metering. - High Efficiency: Maintains performance even with fluids up to 1,000,000 cP viscosity and solids content up to 40%. - Low NPSH Requirement: Reduces the risk of cavitation, enhancing reliability. Applications - Chemical Processing: Transfer of acids, solvents, and abrasive slurries. - Food & Beverage: Hygienic pumping of syrups, creams, and dairy products. - Wastewater Treatment: Handling sludge, lime slurry, or abrasive mixtures. - Marine & Offshore: Fuel transfer, bilge pumping, and ballast water handling. Maintenance & Reliability The sealed bearing assembly and replaceable stator extend service life, while the simple mechanical seal or packing gland options reduce leakage risks. Routine maintenance involves inspecting the stator for wear and ensuring proper lubrication of bearings. Conclusion The G-Type All-Stainless Steel Screw Pump combines ruggedness, precision, and adaptability, making it a reliable solution for challenging fluid transfer tasks. Its corrosion-resistant build, low maintenance, and ability to handle diverse fluids underscore its value across critical industries.
