ANSI/HI9.1-9.5-2000American National Standard forPumps GeneralGuidelinesfor Types,Definitions,Application,SoundMeasurement andDecontamination000Z-S6-16 IH/ISNHydraulic9 Sylvan WayParsippany,New Jersey07054-3802www.pumps.orgAmericanApproval of an American National Standard requires verification by ANSI that therequirements for due process,consensus and other criteria for approval have been metNationalby the standards developer.StandardConsensus is established when,in the judgement of the ANSI Board of StandardsReview,substantial agreement has been reached by directly and materially affectedinterests.Substantial agreement means much more than a simple majority,but not nec-essarily unanimity.Consensus requires that all views and objections be considered,and that a concerted effort be made toward their resolution.The use of American National Standards is completely voluntary;their existence doesnot in any respect preclude anyone,whether he has approved the standards or not,from manufacturing,marketing,purchasing,or using products,processes,or proce-dures not conforming to the standards.The American National Standards Institute does not develop standards and will in nocircumstances give an interpretation of any American National Standard.Moreover,noperson shall have the right or authority to issue an interpretation of an AmericanNational Standard in the name of the American National Standards Institute.Requestsfor interpretations should be addressed to the secretariat or sponsor whose nameappears on the title page of this standard.CAUTION NOTICE:This American National Standard may be revised or withdrawn atany time.The procedures of the American National Standards Institute require thataction be taken periodically to reaffirm,revise,or withdraw this standard.Purchasers ofAmerican National Standards may receive current information on all standards by call-ing or writing the American National Standards Institute.Published ByHydraulic Institute9 Sylvan Way,Parsippany,NJ 07054-3802www.pumps.orgCopyright 2000 Hydraulic InstituteAll rights reserved.No part of this publication may be reproduced in any form,in an electronic retrieval system or otherwise,without priorwritten permission of the publisher.Printed in the United States of America1SBN1-880952-43-2ContentsPageForewordV9 Pumps-general guidelines9.0Scope.19.1Types of pumps.19.1.1Positive displacement pumps.19.1.2Kinetic pumps.19.2Definitions.39.2.1Hardware terms.39.2.2Slurry application terms.59.3Design and application.79.3.1Preferred measurement units and conversion factors.79.3.2Materials.119.3.3Common polymer materials of construction for various liquids.379.4Measurement of airborne sound.509.4.1Instrumentation.509.4.2Operation of pumping equipment.509.4.3Test environment.509.4.4Microphone locations,.,.,509.4.5Measurement technique.519.4.6Measurements to be taken.519.4.7Calculation and interpretation of readings.529.4.8Presentation of data.529.4.9Airborne sound level test report.539.5Decontamination of returned products procedure.61Appendix A Bibliography.62Appendix BIndex.63Figures9.1-Types of pumps.29.2-General ranking of cavitation erosion resistance of commoncast metals when pumping clear water at ambient temperature.289.3-Correction for background sound.549.4-Horizontal end suction centrifugal pump.549.5-Axially split case centrifugal pump.55讲9.6-Vertical in-line centrifugal pump.559.7-Double case centrifugal pump.569.8-Axially split case multistage centrifugal pump.579.9-Horizontal reciprocating pump.579.10-Vertical reciprocating pump.589.11-Horizontal rotary gear pump.599.12-Horizontal rotary screw pump.599.13 Vertical rotary pump.60Tables9.1-Examples of rounded equivalents.79.2-Hydraulic Institute-Preferred measurement units andconversion factors.89.3-Materials of construction for pumping various liquids.299.4-Polymers used in pump construction.389.5-Guide for maximum continuous temperature(C)liquid vs.material selection for polymer pumps.409.6-Guide for maximum continuous temperature(F)liquid vs.material selection for polymer pumps.45iv
