Commonly used standards for heavy-duty chemical process pumps are API 610 and VDMA 24297A. API 610 is a standard developed by the American Petroleum Institute to provide a procurement specification for the manufacture and procurement of centrifugal pumps. API610 standard since its birth, has undergone a number of revision and renaming, and the content also has a larger change. Heavy duty chemical process pump commonly used standard brief API610 on energy issues of concern. API 610 requires manufacturers and end users to actively seek innovative and energy-saving methods in the manufacturing, selection and operation of equipment. This method of saving energy should be encouraged if it increases efficiency and reduces the total cost of use without sacrificing safety or reliability. In addition, the evaluation criteria for the selection of equipment should be based on the total cost of the equipment over its useful life, rather than the equipment procurement costs. Currently in the oil and chemical industries, API610 is the most frequently used centrifugal pump with international standards. International Organization for Standardization also adopted the API610 standard, paid to the standard number ISO / CD13709. API 610 sets minimal requirements for centrifugal pumps used in the petroleum, heavy chemical and natural gas industries, including pumps used for reverse operation as hydraulic recovery turbines. Centrifugal pumps complying with the API 610 standard are often referred to as API pumps. API pump continuous operation cycle of at least 3 years, high reliability. The API pump is suitable for a wide range of applications. There are three major types of pumps involved in this type of pump, namely Overhung, Between Bearings and Vertical Suspended. Table 1. Of these, OH1, OH4, OH5 are only available if the purchaser's designation and the manufacturer have proven their experience with the pump.
