Common Standards and Regulations for Chemical Pumps

2023/09/11

In the petrochemical industry, the selection, design, and operation of chemical pumps need to adhere to a series of standards and specifications to ensure safety, reliability, and performance. Here are some common standards and specifications for chemical pumps:

1.API Standards (American Petroleum Institute):

API 610: Standard for centrifugal pumps, covering various applications including oil, petrochemicals, natural gas, and chemicals.

API 674: Standard for reciprocating (positive displacement) pumps, used for high viscosity or high-pressure applications.

API 675: Standard for screw pumps, used for metering and mixing applications.

API 676: Standard for gear pumps, suitable for high-flow and low-viscosity fluids.

API 682: Standard for mechanical seals and seal systems.

2.ANSI Standards (American National Standards Institute):

ANSI B73.1: Standard specification for chemical process pumps.

ANSI B73.2: Standard specification for screw pumps.

ANSI B73.3: Standard specification for centrifugal pumps.

ANSI B73.4: Standard specification for gear pumps.

3.ISO Standards (International Organization for Standardization):

ISO 5199: International standard for chemical pumps, similar to API 610.

ISO 2858: International standard covering standard centrifugal pumps.

ISO 4072: International standard for positive displacement pumps.

ISO 15783: International standard for gear pumps.

4.NEMA Standards (National Electrical Manufacturers Association):

NEMA MG 1: Standard for the interaction of motors and pumps.

5.ASME Standards (American Society of Mechanical Engineers):

ASME B73.1: Specification for chemical process pumps.

ASTM Standards (American Society for Testing and Materials):

ASTM D396: Standard specification for fuel oils, applicable to fuel oil pumps.

6.HI Standards (Hydraulic Institute):

HI 1.1-1.2: Standards for centrifugal pumps.

HI 3.1-3.5: Standards for positive displacement pumps.

HI 9.6.6: Standards for screw pumps.
