ASME B73. 1 requires Class 150 flanges for ductile iron and alloy steels as a minimum (280 psig /19.3 bar) at ambient temperature. ISO 5199 specifies PN16 flanges (16 bar / 232 psig). Although neither specification is limited to applications for 50Hz countries, generally speaking ASME B73.
ASME/ANSI flanges are common in industrial process systems handling water, steam, air and gas. API flanges are manufactured for high strength operating refinery systems with products such as oil and explosive gases.
Sealless Pumps ANSI and API Magnetically Coupled Process Pumps. Hot Oil Circulation Pumps with Magnetic Coupling. Side Channel Pumps with Magnetic Coupling. MAG-Safe Monitoring Device. Vertical Pumps with Magnetic Coupling. Mag-Drive Gear Pumps. Multistage Centrifugal Mag Drive.
By definition, these chemical pumps are horizontal, end suction single stage, centerline discharge, centrifugal pumps comparable in size and dimensions regardless of pump manufacturer. These pumps are required to meet the ANSI / ASME B73. 1 standard of the American Society of Mechanical Engineers (ASME).
The widely referenced centrifugal pump standard known as ASME B73. 1 can trace its origins as early as 1955, when efforts to develop chemical pump standards began. This later evolved into the American Voluntary Standard in 1962 and, in conjunction with a similar Hydraulic Institute standard, became ANSI B73.

The ASME, or the American Society of Mechanical Engineers, provides codes that govern the safety of mechanical equipment. These codes are meant to provide overarching specifications for mechanical engineering applications. The API, or the American Petroleum Institute, on the other hand, produces recommended guidelines.
ANSI pumps meet standards set forth by the American National Standards Institute, while API pumps are engineered to standards defined by the American Petroleum Institute. As you may have guessed, the API 610 Standard focuses more specifically on refinery and oil gas applications, whereas the ANSI B73.
As you may have guessed, the API 610 Standard focuses more specifically on refinery and oil gas applications, whereas the ANSI B73. 1 standard applies to a wider range of industries.
