This standard specifies the technical requirements for the design, manufacturing, testing, acceptance, marking, packaging, transportation, and storage of high-speed centrifugal pumps (hereinafter referred to as centrifugal pumps). This standard is applicable to high-speed pumps used in the petroleum industry, chemical industry and natural gas industry. It is suitable for transporting acids, alkalis, alcohols, benzene, hydrocarbons, oils, alcohols, medicines, etc., with a viscosity of less than 0.5Pa· s, fluid medium with temperature -130℃~260℃. It is a vertical or horizontal high-speed centrifugal pump with a power of 1.1kW ~ 560kW, a flow rate of 0.6m³/h ~ 140m³/h, a lift of 11m ~ 3049m, and a rotation speed of 3000r/min ~ 23700r/min. Other similar high-speed centrifugal pumps can refer to this standard.
