OEM Aftermarket ANSI Pump Spare Parts
"ANSI PUMP" typically refers to horizontal end-suction centrifugal pumps that comply with the American ANSI/ASME B73.1 standard. These pumps are specifically designed for medium-low pressure and medium-temperature industrial applications such as chemical processing and oil refining, featuring a rear-pull design, standardized interfaces, and a cantilevered impeller.
Standard Reference: ANSI/ASME B73.1M (latest edition is B73.1M-2020), which specifies the dimensions, performance, materials, and testing requirements for horizontal end-suction centrifugal pumps used in chemical applications. It is not formulated by ANSI itself but issued by ASME under the authorization of ANSI.
Typical Features: Single-stage, single suction, horizontal split or rear pull-out structure, flange conforming to ANSI B16.1/B16.5, suitable for clean or mildly corrosive liquids (viscosity typically ≤3000 cSt), working pressure generally ≤20 bar, temperature ≤260°C.
Main manufacturers: Flowserve (such as Mark 3 series), Sulzer (CPE series), ITT Goulds, Dover (PSG), Xylem, KSB, etc. all provide ANSI B73.1 compatible pumps
