The screw pump standard refers to a set of guidelines, specifications, and requirements that govern the design, manufacture, testing, and usage of screw pumps. These standards are established to ensure that screw pumps meet specific technical criteria, performance levels, and safety standards, promoting consistency, reliability, and interoperability across different manufacturers and applications.
Various organizations and standardization bodies develop screw pump standards. Some of the common international and industry-specific screw pump standards include:
ISO 2858: This standard defines the main dimensions and performance parameters of centrifugal screw pumps used for general purposes.
ISO 5199: It specifies the design and performance requirements for centrifugal screw pumps handling corrosive and abrasive fluids in industrial processes and chemical applications.
API 676: The American Petroleum Institute (API) standard for rotary-type positive displacement screw pumps, often used in the oil and gas industry.
ANSI/HI 3.6: Developed by the Hydraulic Institute (HI), this standard covers the design, installation, operation, and maintenance requirements for rotary screw pumps.
DIN 24255: A standard by the German Institute for Standardization (DIN) that applies to the design and performance requirements of rotary screw pumps.
GB/T 10886: A Chinese national standard that specifies terms, classifications, dimensions, and performance parameters for rotary screw pumps.
These standards outline essential aspects such as pump construction, materials, performance curves, testing methods, and operational limits. Manufacturers and users can refer to these standards to ensure that screw pumps are designed, produced, and operated consistently and safely.
Adherence to the screw pump standard enables better comparison and evaluation of different pump models, enhances compatibility with existing systems, and ensures reliable and efficient pump operation in various industrial applications.
