Sulzer CPT21-1B ANSI Pump | 3" x 1.5" | Duplex Stainless Steel | 200 GPM

Sulzer CPT21-1B ANSI Process Pump | 200 GPM | Duplex Stainless Steel

The 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.
