Visit pumps.org to verify the latest edition number (currently aligning with the HI Pump & System Standards 2023-2024 updates). Ensure your team is working from the current data, not a 15-year-old "Orange Book" that lacks modern slurry and high-temperature data.
HI revises the Data Book periodically. Significant updates occur when new research on viscosity effects, slurry transport, or pump efficiency testing is validated. As of the latest edition (the 4th or 5th, depending on revision cycle), content on VFDs, energy cost analysis, and pump system optimization has been greatly expanded. hydraulic institute engineering data book
: It acts as a companion to the Hydraulic Institute Standards , providing the raw data and explanatory information that supports official industry standards. Core Technical Content Visit pumps
When a pump designed for water (specific gravity 1.0, viscosity 1.0 cSt) is used to pump oil (viscosity > 50 cSt), internal hydraulic friction increases. This results in: Significant updates occur when new research on viscosity
