  • About HI
  • New Releases

The Hydraulic Institute (HI)—the largest association of pump industry manufacturers in North America—has served member companies and pump users by providing product standards and a forum for the exchange of industry information. HI has established itself as one of the leading developers of pump standards. It offers a wide variety of programs and services, each tailored to user needs: standards development, networking opportunities, access to specific statistical data and economic reports, electronic services, educational materials, breaking industry news, participation in industry initiatives and more.

 

HI standards are developed by industry experts from all areas of interest. They help in making more informed decisions in the design, manufacture and operation of all major pumps, with regards to positive displacement, and rotodynamic of centrifugal, mixed and axial flow types, rotary-reciprocating mechanism, for greater performance optimization.
