ITT Goulds Pumps
3600i API 610 (BB3)
The Goulds 3600i is an axially split, multistage, between-bearings pump built to API 610 as a type BB3 machine. It is the class of pump plants turn to when a single-stage design simply cannot generate enough head, combining opposed impellers and a dual-volute casing for balanced, reliable high-pressure service.
Product Benefits
- Tamed rotor forces: High-head multistage duty puts severe axial and radial forces on a rotor. The 3600i mounts precision investment-cast impellers in an opposed configuration specifically to tame them.
- Dual-volute casing: The dual-volute design balances radial loads, even with light or volatile fluids.
- Patented oil filtration: A patented bearing oil filtration system continuously removes moisture and debris from the lubricant during operation, protecting the bearings that everything else depends on.
- Easy rotor inspection: The axially split casing means the rotor can be inspected without disturbing the piping.
Where It's Used
- High-pressure process duties: The 3600i serves high-pressure services in refining and petrochemical processing, along with high-temperature boiler feed.
- Injection and reverse osmosis: It also covers reverse osmosis and CO₂ and water injection duties.
- Powerhouse boiler feed: In pulp and paper mills, Fluindo positions it for the demanding high-head services of the powerhouse, above all boiler feed, where continuous availability is essential.
Good to Know
- Low-NPSH option: An optional double-suction first stage is available when suction conditions are marginal and low NPSH is needed.
- Flexible bearing arrangements: Bearings range from standard anti-friction up to fully hydrodynamic arrangements.
- API 682 seal ready: Seal chambers follow API 610 dimensions and accept a wide range of API 682 cartridge mechanical seals, and the rotor is balanced to a fine ISO grade.
- Renewable wear parts: Impellers carry integral wear surfaces as standard, with renewable wear rings available, including non-metallic options.
- High-pressure flanges: Several high-pressure flange classes and facings can be specified.
