HI Debuts Updated Standard for Rotary Pump Tests

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/commercial rotary positive displacement pumps and includes detailed procedures on the set up and methods for conducting hydrostatic test and performance tests of such pumps. ANSI/HI 3.6-2010 is immediately available for purchase through the HI online retail store. It is offered at $75.00.

Significant updates include: complete reformatting of the Standard to a one-column layout for easier reading; use of larger graphics and figures; 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.

According to Gregg Romanyshyn, HI Technical Director, “This standard recognizes two levels of performance tests for rotary pumps and provides procedures for conducting and reporting each test level. The test levels have been designed to permit selection of tolerances and accuracy appropriate for the application and the customer’s needs. Hydrostatic Test and Net Positive Inlet Pressure Required Test are separate tests and are both optional tests. Vibration and acoustical testing are not included.” 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 Corporation, Milton Roy Americas, Moyno, Inc., Roper Pump Company, 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, 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 user-friendly, and available in both electronic and print formats at the HI e-Store: http://eStore.Pumps.org.
