API610 and VDMA24297A are common standards for heavy-duty chemical process pumps. API, short for American Petroleum Institute. The purpose of publishing API 610 standards is to provide a procurement specification to facilitate the manufacture and procurement of centrifugal pumps. The API 610 (Seventh Edition) is a centrifugal pump for petroleum refinery proposed under the standard name "Centrifugal Pumps for General Refinery Services." However, in fact, the API610 standard is not only used in the oil refinery, petroleum, chemical, natural gas and other fields are often used API610 standard. To meet this need, API 610 (Eighth Edition), renamed in 1995 as "Centrifugal Pumps for Petroleum, Heavy Chemical, and Gas Industry Services" A version of the larger changes. API610 is concerned about the issue of energy saving. 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 those used as reversing pumps for 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.
