USED SULZER CPT21-1B

Sulzer CPT21-1B ANSI Process Pump | 200 GPM | Duplex Stainless SteelThe Sulzer CPT series is the benchmark for reliability in chemical processing. This CPT21-1B model (Size 3x1.5-6) is constructed from high-grade Duplex Stainless Steel (ASTM A890 3A), offering significantly higher resistance to pitting, stress corrosion cracking, and erosion than standard 316SS. Designed for high-efficiency fluid transfer, this unit delivers a steady 200 GPM, making it ideal for acids, salts, and aggressive process chemicals.Built on a heavy-duty power frame with Inpro/Seal VBX isolators, this pump is engineered to minimize shaft deflection and maximize bearing life. The "back pull-out" design allows for the entire rotating assembly to be removed for maintenance without disturbing the suction or discharge piping, ensuring your facility maintains maximum uptime.Technical SpecificationsManufacturer: SulzerModel: CPT21-1B (ANSI B73.1 Standard)Size: 3x1.5-6 (3" Suction / 1.5" Discharge)Material: Duplex Stainless Steel (ASTM A890 3A)Performance: 200 GPM @ 3550 RPMMax Head: ~210 Feet TDHPower Frame: Heavy-Duty with Oil Bath LubricationImpeller: Semi-Open Investment CastKey FeaturesDuplex Stainless Steel Construction: Provides superior chemical compatibility and structural integrity, outperforming 316SS in high-chloride and acidic environments.Maintenance-Optimized Design: The back pull-out feature and external impeller adjustment allow for rapid service and efficiency restoration without pump disassembly.High-Efficiency Hydraulics: Investment-cast internals provide smooth flow paths, reducing energy consumption and internal wear.ANSI Standardization: Fully interchangeable with any standard 3x1.5-6 ANSI piping configuration, making it a perfect "drop-in" replacement or critical spare.
