For several decades, lobe and multistage blowers were the tried-and-true blower technologies for wastewater treatment plants. Over the past 15...
New standards available in electronic or print form
The Hydraulic Institute (HI) has updated the ANSI/HI Standard for Rotary Pump Tests version 2000, and has introduced ANSI/HI 3.6 – 2010, Rotary Pump Tests. This updated standard applies to industrial and commercial rotary positive displacement pumps and includes detailed procedures on the set-up and methods for conducting hydrostatic tests and performance tests of such pumps. ANSI/HI 3.6-2010 is immediately available for purchase through the HI online retail store, http://www.eStore.Pumps.org. It is offered at $75.
Significant updates include complete reformatting of the standard to a one-column layout for easier reading, use of larger graphics and figures and more detailed descriptions, particularly in ”Terminology” sections. Also included is an equation for pump output power.
The new standard provides most current testing procedures and acceptable deviation of dependent test quantities from specified values for Type III and Type IV testing and is intended for use by all testing facilities. The objective of ANSI/HI 3.6 - 2010 is to establish a uniform demonstration of a pump’s ability to perform satisfactorily both mechanically and hydraulically.
A number of leading rotary pump manufacturers served on the committee that developed this standard, including Flow Solutions Group, IMO Pump-Colfax, Intelliquip LLC, Leistritz Corp., Milton Roy Americas, Moyno Inc., Roper Pump Co., Siemens Water Technologies and Weir Floway Inc.
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 or controls, and pump software developers and systems integrators. HI periodically introduces new standards based on industry needs. ANSI/HI 3.6 - 2010, along with HI’s complete library of ANSI/HI Standards for the pump industry, are available in both electronic and print formats at the HI e-Store or by calling the HI’s purchasing line at 973.267.9700.
