KOLEBURG API 685 Pump for Petrochemical Applications
The API 685 Pump standard solves the critical problem of hazardous fluid leakage in heavy industries by establishing strict requirements for zero-emission, sealless magnetic drive centrifugal pumps.
API 685 Pump Standard Introduction
The API 685 standard is primarily utilized in scenarios involving highly toxic, flammable, or explosive chemicals where absolute zero-leakage is mandatory. We need this standard to ensure environmental safety and operational reliability in volatile processes that cannot tolerate mechanical seal failures. Its significance lies in defining robust engineering criteria that prevent catastrophic failures and protect personnel in seal-less Magnetic Drive Pump systems.

API 685 FAQs
Does KOLEBURG manufacture products that fully meet the API 685 standard?
Yes, every sealless magnetic unit we produce is strictly tested and certified to fully comply with the standard, delivering the same rigorous quality as our API 610 Pump line.
Do you provide testing reports for the API 685 Pump?
Absolutely, we provide comprehensive factory acceptance tests (FAT), including hydrostatic pressure tests, performance curves, and complete material traceability reports.
Does KOLEBURG support OEM services and custom logos?
Yes, we offer full OEM capabilities, allowing you to customize paint colors, specialized nameplates, and packaging to meet your specific brand and industrial requirements.
How do I choose between an API 685 and an ANSI B73.1 Pump?
Choose the API standard when handling heavily toxic or flammable liquids in refineries where absolute zero-leakage is legally required, whereas ANSI is more suited for general, less hazardous chemical processing.
What are the primary industry requirements for this sealless equipment?
The petrochemical and oil & gas industries mandate a secondary containment shell and specific magnetic coupling designs to prevent any fluid escape in the event of a primary shell failure.
Can these units handle fluids containing solids?
Generally, sealless equipment requires clean liquids; however, we can equip them with specialized Fluoroplastic Magnetic Drive Pump linings and external flush plans to handle minor, fine particulate matter safely.
What kind of after-sales service does KOLEBURG offer?
We provide global technical support, professional installation guidance, and rapid-dispatch replacement parts for all internal magnetic drive components and specialized bearings.
