Summary This standard specifies the use of magnetic coupling (magnetic drive pump) or shielded motor driven rotary power sealless pump (hereinafter referred to as "pump") requirements. Such pumps are mainly used in chemical processes, water treatment and petrochemical industry, which will be affected by the use of space, limiting environmental or safety regulations, noise. Sealless pumps are fully inclusive refers to the internal transfer within the pressure vessel containing the body of the infusion pump, pressure vessel or the primary sealing device such as mats or O -ring seals and other static sealing. In addition to the special requirements of this standard, the pump should normally meet accepted standards (such as GB/T 5656, explosion, electromagnetic compatibility, etc.). This standard covers the installation and pump, maintenance and operation of safety-related design features, and describes the need between buyers and manufacturers/suppliers by the agreed terms. Under the requirements of the application of this standard has been the case, but also requires a special design features. You can propose an alternative design, but should also be designed to meet this standard description of these intentions, and a detailed description of these designs. Can not be made ??in full compliance with the requirements of the standard pump for consideration, as long as do not meet all of the Department are to be explained. When contain conflicting requirements between multiple documents, which should be executed in the following order, purchase order (or RFQ, if no purchase orders), see Appendix E and Appendix F data sheet (see Appendix C) or technical drawings/technical requirements, c) of this standard, d) other criteria.

Foreword

This revised standard adopts ISO 15783.2002 (first edition) "sealless rotodynamic pump technical conditions Ⅱ class" (in English). This standard is based on ISO 15783.2002 redrafted. For ease of comparison, listed in Appendix A of this standard and reg number ISO 15783.2002 reg control list numbered. According to our country, the present standard in the use of international standards has been modified. These technical differences identified by vertical lines involved in them And the terms of the margin of the page. In Appendix B gives a list of the technical differences and the reasons for the reference. For ease of use, this standard also made the following editorial changes. a) "this International Standard" be replaced by "this standard"; b) use a decimal point instead of a decimal comma ",". ","; c) Delete the international standard "foreword"; d) with "MPa" instead of as a pressure unit "bar", 1bar = 0.1MPa; e) with "r/min" instead of as a speed unit "min-1"; f) in Annex A, Appendix G to increase the figure caption or table title; g) In Annex G, the Arabic numerals "1,2,3" instead of "a, b, c". Appendix C of this standard is a normative appendix, Appendix A, Appendix B, Appendix D, Appendix E, Appendix F, Appendix G, Appendix H, Appendix I is Informative appendix. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee pump (SAC/TC211) centralized. Drafting of this standard.

ISO Introduction This standard is a set of standards for the first sealless pump technology standard conditions. This group has two standard technical conditions, namely Ⅰ And type Ⅱ, type Ⅰ which require more stringent. This standard requires buyers decide or be agreed between the purchaser and the manufacturer/supplier terms in the corresponding standard text Terms of use before "*" indicates, and listed in Appendix I. Sealless rotodynamic pump technology conditions (Ⅱ type)

1 Scope

1.1 standard specifies the use of magnetic coupling (magnetic drive pumps) or shielded motor driven sealless rotodynamic pump (hereinafter referred to as "Pump") requirements, such pumps are used in chemical processes, water treatment and petrochemical industry, its use will be subject to space, noise, ring Limit environmental or safety regulations. Sealless pump refers to the internal rotor is completely contained within the pressure vessel containing the infusion pump body, pressure vessel or the primary sealing means, such as by the pad Or O-ring seals and other static sealing. 1.2 In addition to the special requirements specified in this standard, the pump normally shall conform to generally accepted standards (such as GB/T 5656, explosion-proof electrical Magnetic compatibility, etc.). 1.3 This standard includes the installation of the pump, maintenance and operation of safety-related design features, and describes the required by the purchaser and manufacturer/supplier It agreed terms between providers. 1.4 In the application of this standard has requested the case, but also requires special design features that can propose an alternative design, but at the same time should indicate These are designed to meet the intent of this standard, and a detailed description of these designs. May submit for consideration by the pump does not fully comply with this standard, only To all non-compliant place are to be explained.
