The Hydraulic Institute’s comprehensive Rotary Pump Standard ANSI/HI 3.1-3.5. Released in 2008 and substantially updated, this edition has twenty additional pages, 40% more content, and increased educational information. This standard applies to industrial rotary positive displacement pumps. It includes: types and nomenclature; definitions; design and application, operation and maintenance. The updated standard also includes:
Capability tables in both metric and US customary units providing comparisons of rate of flow, pressure, viscosity, solids and abrasive handling, reversible rotation, and power range for 11 different types of rotary pumps;
A consolidated range chart providing a comparison of pressure and rate of flow in both metric and US customary units for 11 different rotary pump types;
Detailed explanation of each rotary pump type including basic operation, design features, typical applications, and driver requirements;
New and updated cross-sectional illustrations of popular rotary pump designs;
Revised and expanded list of definitions;
Listing of viscosities of common fluids;
Plot of efficiency vs. rate of flow for different pump types;
A completely new section on multiphase pumps for oil and gas applications.
