Hydraulic Institute Publishes Rotodynamic (Vertical) Pumps for Nomenclature and Definitions

Press release date: Jan 12, 2009

Parsippany, NJ, January 16, 2009 - Hydraulic Institute (HI), the pump industry's knowledge leader and foremost resource for pump education, has published a new American National Standard for Rotodynamic (Vertical) Pumps for Nomenclature and Definitions (ANSI/HI 2.1-2.2-2008).

This standard applies to vertically suspended pumps, including single casing (open pit intake) submersible pumps and discharge through column types (diffuser, volute, and axial flow). Also included are double casing (can or suction barrel intake - diffuser and volute), and in-line casing diffuser pumps.

These pumps are typically driven by vertical electric motors or horizontal engines with right angle gears. The standard also includes types, nomenclature, and definitions for these pumps.

Excluded from the scope of this document are:
A) vertical in-line pumps
B) horizontal centrifugal pumps mounted vertically such as sewage pumps
C) vertical, overhung impeller, close coupled, and submersible single stage submersible pumps

The Standard, designated by HI product code A105, is available in hard copy or secure PDF format from the Hydraulic Institute for $85.00. For more information, or to order, visit the HI e-Store at estore.pumps.org, or call (973) 267-9700 X18. HI Pump Standards are reliable, widely accepted references for anyone involved in pumps, including users, consultants, contractors, construction firms, manufacturers of pumps, seals, motors, instrumentation, controls, and pump software developers and systems integrators. HI periodically introduces new Standards based on industry needs.
