scope:

This standard applies to industrial/commercial rotary positive displacement pumps. It includes types and nomenclature; definitions; design and application; and installation, operation, and maintenance. It does not include standards on magnetic drives for sealless pumps (see ANSI/HI 4.1-4.6 Sealless, Magnetically Driven Rotary Pumps for Nomenclature, Definitions, Application, Operation, and Test) nor rotary pumps primarily used for fluid power applications. For information on rotary pump tests, see ANSI/HI 3.6 Rotary Pump Tests.

A comprehensive overview of features and attributes of rotary pumps is presented in Sections 3.1.1 through 3.1.7.2.2, which contain descriptive material covering the basic technologies highlighted in Figure 3.1. These include a description of each configuration, typical applications, and general operating ranges for commercially available designs for viscosity, flow, and pressure. Operating ranges stated represent only a single hydraulic parameter and do not indicate that all maximum conditions can be met simultaneously. Suppliers should be contacted for such details.

Purpose

This standard sets out requirements, recommendations, and statements to define, select, apply, operate, and maintain rotary pumps. Requirements convey criteria to be fulfilled if compliance with the document is to be claimed and from which no deviation is permitted. Recommendations convey that, among several possibilities, one is particularly suitable, without excluding or prohibiting others.
