The Hydraulic Institute (HI) members have approved a bylaw change, which broadens eligibility for Associate membership to include all corporations that manufacture products or develop software for ultimate use in or with pumps and pumping systems.

The new bylaw permits corporations and firms engaged in the manufacture of such products as: motors, variable-speed or other drivers; seals and sealing systems; bearings; component parts; gears; couplings; gauges; instrumentation and controls; coatings; lubricants and lubricating systems; and the design and development of pump-specific software, regardless of location where that manufacture occurs, to become Associate members of HI, provided that the corporation or firm sells into the North American market.

Also eligible for Associate membership are corporations or firms whose primary business is integration, manufacture, and assembly of pumps and pumping components into a system or modular solution. Eligibility is not dependent on the location where the integration, manufacture, and assembly occur, but rather on the provision that the corporation sells such products into the North American market.

The Hydraulic Institute says by opening membership eligibility to new pump-specific manufacturing specialties it gains additional expertise and manpower in the development of its ANSI/HI Pump Standards. Additionally, by joining HI, supplier and software companies become eligible for benefits available to HI Associate members.
