Types of pumps supported at both ends mainly include the following:
D series multistage pump: This is a horizontal single-casing multistage centrifugal pump. The first-stage impeller can be single-suction or double-suction. It is suitable for the petroleum refining industry, petrochemical industry, and power industry to transport petroleum, refined oil, liquefied petroleum gas, and other flammable, explosive, or toxic high-temperature and high-pressure liquids that do not contain solid particles. G series high-temperature and high-pressure double-casing multistage pump: This is a horizontal double-casing multistage centrifugal pump. The first-stage impeller can be single-suction or double-suction. The inner casing can be pulled out for maintenance without disassembling the pipeline. It is suitable for the petroleum refining industry, petrochemical industry, and power industry to transport petroleum, refined oil, liquefied petroleum gas, and other flammable, explosive, or toxic high-temperature and high-pressure liquids that do not contain solid particles. H series single-stage double-suction centrifugal oil pump: This is a horizontal, two-end supported, radially split, double-volute 1-stage, 2-stage or 3-stage centrifugal pump, suitable for high or low temperature and high pressure conditions in industries such as oil refining, petrochemicals, coal-to-oil, and natural gas processing. It can convey corrosive or highly corrosive media with solid particles, liquefied petroleum gas, and other flammable, explosive, or toxic media. S series axially split double-suction pump: This is a horizontal, single-stage, double-suction centrifugal pump. The pump body is horizontally split, and the suction and discharge pipes are evenly arranged in the lower pump body in the form of a pipeline. The pump can be maintained and repaired without removing the pipeline and motor. It is widely used in various industrial processes, sewage treatment, power stations, thermal power plants, pipeline pressurization, crude oil or refined oil transportation, natural gas transportation, water conservancy irrigation, water supply and water treatment, seawater desalination, etc. In addition, there is an AY oil pump, which is mainly modified from the Y-type oil pump. The types include single-stage single-suction cantilever type, single-stage double-suction cantilever type, single-stage double-suction two-end support type, two-stage double-suction two-end support type, two-stage single-suction two-end support type, etc. This type of pump has a simple structure and is suitable for the chemical industry, especially for occasions with limited space. It uses mechanical seals and is suitable for conveying non-clean water media.
