API 610 Process Pumps & Replacement Solutions
API 610 pump solutions for refinery, petrochemical and severe-service duties, led by the Goulds 3700 replacement platform and supported by new-project OH2 selection.
Goulds 3700 Replacement Pump
Existing 3700 pump data provides the starting point for replacement verification.
Start With the Pump Information You Already Have.
Use the existing size, duty point, datasheet, performance curve, GA drawing or purchasing description. The review focuses on the complete replacement context rather than a model name alone.
Detailed 3700 engineering information is available on the dedicated replacement page.
Includes the OH2 platform used for centerline-mounted severe-service applications.
Reviewed when duty, energy level and project specification call for a BB arrangement.
Reviewed for vertical project requirements, pits, cans, sumps and suction constraints.
API 610 OH2 Process Pump
For new API 610 / ISO 13709 OH2 duties that are not tied to an existing Goulds 3700 installation. Final configuration is selected around the actual duty, process conditions and project specification.
Final pump selection is confirmed against the reviewed duty point, process conditions and project specification.
What Starts an OH2 Selection?
Start with the duty point and process information available for your project.
Four Checks Before an API 610 Pump Is Released
Each review addresses the engineering factors that govern pump selection.
Duty & Operating Range
Flow, head, speed, impeller, NPSH and expected operating range.
Mechanical Fit
Nozzles, shaft centerline, baseplate, coupling and package interfaces.
Materials & Conditions
Pressure, temperature, process liquid, corrosion and metallurgy.
Auxiliary Systems
Mechanical seal, API plan, driver, lubrication, cooling and documentation.
Start With What You Already Know
New projects and replacement projects should not be forced through the same first-step questionnaire.
New API 610 Project
Use this route when the requirement begins with a new process duty or project specification.
- Flow / head
- Process liquid
- Temperature / pressure
- Material requirements
- Seal and package requirements
Existing Pump Replacement
Use this route when an installed pump or procurement reference already exists.
- Existing model / size
- Nameplate or datasheet
- Performance curve
- GA / nozzle arrangement
- Purchasing specification
From Review to Pump Release
A clear engineering process supports each pump selection and release.
Working from an installed Sulzer model? ZA / ZE / ZF and other Sulzer families stay in the existing Sulzer Replacement Hub instead of being duplicated here.
