19、Committee B73, Chemical Standard Pumps, formed a seallesspump working group to develop a standard for sealless pumps that would correspond toASME B73.1M, Specification for Horizontal End Suction Centrifugal Pumps for Chemical Process.Though these pumps are sealless (i.e., they do not use a dynamic s
20、eal to prevent leakage aroundthe drive shaft), leakage can occur as a result of certain types of wear or misoperation. The usermust take appropriate supplemental safety precautions when operating these pumps.The first edition of this Standard was approved as an American National Standard onAugust 7,
21、 1997.In the intervening years, work continued on a revision of ASME B73.1M. As that work drewnear to completion, the sealless working group began to develop a revision of the 1997 editionof ASME B73.3M to reflect the changes being made in ASME B73.1M. The 2003 revision of theASME B73.3 Standard inc
22、ludedW Some paragraphs were simplified and clarified.W The presentation of units was changed to reflect that the U.S. Customary units were the primaryunits of measurement.W The sections on flanges and flange loading were revised.W Sound and vibration requirements were revised.W Information concernin
23、g “Operating Region” and “NPSH Margin” was added.W Auxiliary connection symbols were added.W Additional pump sizes were added.W Table 3 was revised to reflect changes in the Frame 1 pump dimensions.W Table 7, Minimum Continuous Flow, was added.W Form 1 was revised to reflect additional required valu
24、es.This revision of the Standard includes several changes to reduce redundancy in the B73 set ofstandards and to better align with the Hydraulic Institute standards. Revisions have also beenmade to further improve the reliability of the B73.3 pumps. Reference is now made to the HydraulicInstitute st
25、andard for fluid circulation piping plans. A material classification code has been addedto B73.3. The table for ASTM material specifications has been expanded and a table for minimumrequirements for auxiliary piping materials has been added. Requirements for the bearing framehave been revised to ass
26、ure more robust pumps. Plastic lined magnetic drive pumps have beenadded to the scope of the standard due to their prevalence throughout the chemical industry.Close coupled pumps are also an option and close coupled pump baseplates have been shortenedaccordingly. The default performance test accepta
27、nce grade has been revised to reflect the newHI/ISO performance test standard. More detail was added to the required drawings: curve anddocumentation that should be included with the pump. A new data sheet has been developedand added to the standard. The standard endorses the Electronic Data Exchang
28、e standard whichwas developed by the Hydraulic Institute and FIATECH Automating Equipment InformationExchange (AEX) project.Suggestions for improvement of this Standard will be welcome and should be sent to TheAmerican Society of Mechanical Engineers, Attn.: Secretary, B73 Committee, Two Park Avenue
