The Goulds API Portfolio table confirms these limits for the 7200CB model:

• Capacity: 4000 GPM (910 M³/Hour)
• TDH: 9000 Feet (2740 Meters)
• Temperature: 800 ºF (425 ºC)
• Pressure: 4000 PSIG (275 kg/cm²)

Mechanical / hydraulic

• Design Standards: API 610 11th Edition / ISO 13709 2nd Edition. The Model CB has been upgraded to the 11th edition.
• Pump Type: API BB5 Barrel Multistage, Radially Split, In-Line Diffuser Type.
• Impeller Arrangement: In-line diffuser type design. Key driven and shrink fit impellers are secured against axial movement in both directions.
• Diffusers: Metal-to-metal stage casing fits. Features a fully-shrouded diffuser standard to increase reliability by nearly eliminating diffuser fatigue.
• Rotor Design: Precision investment impeller castings and a dynamically balanced rotor contribute to low vibration. Robust rotor design includes a large stepped shaft and higher L³/D⁴ ratios.
• Barrel Outer Casing: Centerline mount, radial split, full design pressure. Features a cast barrel and nozzles. Custom nozzle locations/orientation are available.
• Cartridge Assembly: Pull-Out Cartridge Assembly. Stage casings are sealed by discharge pressure. The cartridge can be removed on larger pumps with the cartridge assembled.
• Balance Drum: Designed to reliably balance axial forces over the allowable flow range and clearances.
• Bearing Bracket: Rigid 360° Bearing Bracket options include Ball radial and duplex thrust, or Pressure lubricated sleeve radial / tilting pad thrust. Features INPRO™ isolators.
• Flanges: Heavy duty class 900#, 1500#, and 2500# RF or RTJ flanges. 600# and 900# are available on the suction flange.
• Seals: API 682 Seals, accepting a wide variety of seals, seal options, and flush plans per API 610 and API 682.
• Wear Parts: Integral wear parts are available in a variety of API metallic and non-metallic materials and coatings.
• Hydraulic Performance: Two sets of curves are available: one optimized for maximum head-per-stage, and a second set optimized for maximum efficiency.
• Maintenance: Easy Maintenance design allows customers to quickly dismantle and remove the complete cartridge using a BB5 cradle tool, with the pump casing and nozzles remaining connected.

General Notes

• The Model CB has over 30 years of successful installations.
• Testing facilities are capable of 8000 HP / 6000 kW testing.
