    Amarinth API 610 OH3 in-line process pump - J series Pump ...
    An OH3 chemical process pump is a vertical, in-line, single-stage, overhung centrifugal pump designed to API 610 standards. Featuring a separate bearing bracket, it handles high-temperature, high-pressure, or hazardous chemicals in critical applications. Its vertical, compact design saves space and allows for easy maintenance. 
    Key Features and Design 
    • Vertical In-line Configuration: The motor is mounted on a bracket above the pump, connecting via a flexible coupling.
    • Independent Bearing Bracket: Unlike OH4 pumps, OH3 pumps have a separate bearing housing, allowing for more robust construction and flexible coupling use.
    • API 610 Compliance: Specifically designed for refineries, petrochemical, and chemical process industries.
    • Reliability: The design includes wear rings and balance holes to manage axial thrust, and the power end supports heavy loads. 
    Typical Applications 
    • Refineries and Petrochemicals: Handling hydrocarbons and chemical transfer.
    • Critical Services: High-temperature chemical processes and high-pressure duties.
    • Cryogenic Service: Transporting liquids like liquid ammonia or nitrogen.
    • Industrial Utility: Water treatment, boiler feed, and high-rise fire systems. 
    Common Models 
    • Goulds 3910: A prominent API 610 OH3 vertical in-line process pump.
    • Flowserve HWX: A commonly used OH3 pump in petrochemical industries.
    • Rodelta ETLS: A heavy-duty, high-temperature OH3 process pump. 
    These pumps are optimized for applications where space is limited but high reliability is necessary, providing a robust solution for demanding liquid transfer tasks.
