ANSI/HI 3.1-3.5-2008 (A109)

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 standardson magnetic drives for sealless pumps nor rotary pumps primarily used for fluid power applications.

In order to provide a comprehensive overview of features and attributes of rotary pumps, Paragraphs 3.1.2 through3.1.8.2.2 contain descriptive material covering the basic technologies highlighted in Figure 3.1. These include adescription of each configuration, typical applications, and general operating ranges for commercially availabledesigns for viscosity, flow, and pressure. Operating ranges stated represent only a single hydraulic parameter anddo not indicate that all maximum conditions can be met simultaneously. Suppliers should be contacted for suchdetails.
