Goulds 3600 API 610 (BB3)

Summary

Product Identification

The Goulds 3600 is a heavy-duty, between-bearing, axially split, multistage pump designed for high-head and high-capacity services.

• Compliance: API 610 / ISO 13709 Latest Edition (API BB3 Compliance is Available)
• Typical Applications:
  • Petroleum refining, production, and distribution
  • Petrochemical and demanding chemical processing
  • High temperature applications including boiler circulation
  • General industrial requiring high temperature or high pressures
  • Refineries, injection offshore platforms, remote pipeline
  • Boiler feed in mid-range cogeneration
  • Descaling, mine dewatering, process transfer
  • Desalination and CO₂ injection

Operating Limits

• Capacities: to 8,500 GPM (1930 m³/h)
• Heads: to 9,000 feet (2740 m)
• Temperatures: to 400° F (205° C)
• Pressures: to 4,000 PSIG (275 bar)

Design Features

• Hydraulics: Engineered hydraulics with dense hydraulic coverage; custom hydraulics available.
• Packaging: Engineered packaging with a wide range of drivers, seals, piping, nozzle configurations, flanges, baseplates, and QC testing.
• Casing: Axially split casing for ease of maintenance. Dual volute design balances hydraulic radial thrust at each stage for extended seal/bearing life.
• Bolting: Heavy-duty single row bolting prevents distortion and interstage leakage. All nuts located on top for ease of maintenance.
• Impellers: Precision cast impellers with smooth, dimensionally consistent hydraulic passages for maximum efficiency. Dynamically balanced impellers and rotors ensure smooth operation. Impellers are shrink fit to shaft and independently secured against axial movement. Impellers are mounted on shaft with vane tips staggered for reduced pressure pulsations. Rotor and impeller balanced to stringent ISO 1940 Grade 1.0 (exceeds API minimum).
• Crossover: Compact crossover for streamlined fluid flow, minimum friction loss, and maximum efficiency.
• Axial Balance: Opposed impeller arrangement provides permanent hydraulic axial balance.
• Flanges: Heavy Duty ANSI B16.5 Flanges, Class 900 RF standard on suction and discharge; other classes available as options.

Mechanical / Hydraulic Details

• Serviceability:
  • Cartridge type mechanical seals for ease of assembly and proper installation.
  • Single row bolting with stud nuts located on upper half for easy accessibility.
  • Entire rotating assembly can be removed for maintenance without disturbing suction/discharge piping.
  • Split stage pieces and center case bushing can be removed for inspection of wear surfaces without disassembling rotor assembly.
• Bearing Arrangements (Standard & Optional):
  • Standard: Oil lubricated ball radial and duplex thrust bearings.
  • Optional: Ring oil lubricated sleeve radial and ball thrust, or pressure lubricated sleeve radial and tilting pad thrust bearings. Hydrodynamic bearings offered with pressurized oil lube systems.
• First Stage Impeller: Double suction first stage impeller available on 4-inch and larger discharge size pumps for services where NPSHA is limited.
• Shaft Sealing and Seal Chambers: Seal chambers meet API 610 / ISO 13709 dimensional requirements. Can be fitted with single, double, or tandem cartridge mechanical seals, including API 682 seals. Non-metallic rings available for low specific gravity applications, increased efficiency, or ability to withstand short periods of dry running.
• Destaging: Can be supplied with one or more blank stages to meet existing head conditions and allow for future increases.
• Instrumentation Options: Can be furnished with instrumentation to measure vibration and temperature. RTDs or thermocouples for bearing temperatures and casing temperature rise. Bearing housing vibration monitoring for ball bearings. Non-contacting vibration probes for actual rotor vibration on pumps with sleeve bearings.
• Interstage Bleedoff: Available for multiple discharge conditions.
• Hydraulic Coverage: Offers extensive hydraulic coverage to meet process needs, representing 80% to 110% of best efficiency point (BEP) for both 60 Hz and 50 Hz operation.
