The Hydraulic Institute (HI) is the global authority on pumps and pumping systems.HI is a pump association of positive displacement and rotodynamic, centrifugal pump manufacturers and suppliers whose mission is to be a value-adding resource to member companies, engineering consulting firms, and pump users worldwide. HI develops comprehensive pump standards, guidelines and guidebooks and serves as a forum for pump industry information and collaboration through volunteer participation and at pump conferences. HI standards cover pump design and applications, installation, operation and maintenance, pump testing, definitions and nomenclature and address such topics as allowable vibration, pump efficiency, nozzle loads, pump piping, viscosity correction and more.

With the U.S. Department of Energy’s 2011 decision to propose pump efficiency regulation, HI has taken a leading role in representing the pump industry in negotiating fair and appropriate regulations designed to achieve energy savings goals. Refer to DOE Pump Efficiency Rulemaking for further updates.

Pump Systems Matter (PSM) is a non-profit pump education resource established by the Hydraulic Institute, and leading utilities and energy efficiency organizations to serve the pump user community by providing pump training on the benefits of pump system optimization to achieve higher energy efficiency, lower maintenance costs, and improve reliability and profitability
