The Hydraulic Institute (HI), under the approval of the American National Standards Institute (ANSI), is seeking qualified individuals in North America to participate in the review process for the draft of the updated standard, American National Standard for Pumps – General Guidelines for Types, Definitions, Application, Sound Measurement, and Decontamination (ANSI/HI 9.1-9.5-2012).

ANSI/HI 9.1-9.5-2012 has been revised and updated and replaces the prior version that was last reviewed in 2000.This standard applies to industrial/commercial pumps, including positive-displacement and kinetic types. Positive-displacement pumps add energy to liquids by rapping liquid in a confined space and forcibly moving it out of the pump and into the discharge pipe. This pumping action is accomplished by either reciprocating action of plungers, pistons, bellows, or diaphragms; rotary action of mechanical devices such as gears, screws, or vanes; or by blow case arrangements using pressurized air to displace liquid. Kinetic pumps add energy by high-speed rotating wheels or impellers, using either centrifugal effects; regenerative turbine pumping action; or by a rotating case with a stationary arm fitted with a pitot tube.

Individuals and organizations located in North America directly and materially affected by this standard are asked to contact HI. These parties include pump users and specifiers, producers, standards developers, government agencies, and general interest groups. HI is currently assembling a canvass list of all parties interested in reviewing the draft. This list will be submitted to ANSI in order to meet its open canvass requirements.

To participate in the ANSI/HI canvass, contact Gregg Romanyshyn, technical director, at gromanyshyn@Pumps.org or call 973 267-9700, ext. 114.
