Institute Publishes Standard for Vertical Pumps

The 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), according to a recent press release.

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:

  • vertical in-line pumps
  • horizontal centrifugal pumps mounted vertically such as sewage pumps
  • 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. For more information, go to http://estore.pumps.org, or call 973.267.9700 extension 18.

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.

The Hydraulic Institute (HI) is the largest association of pump producers and suppliers to the pump industry in North America and is a global authority on pumps and pumping systems.
