HI’s Circulator Savings Calculator is a tool for users to learn about the potential energy savings and financial payback from the selection of efficient circulators. The savings are based on publicly available data at er.pumps.org, where listed pumps have been tested in certified labs and their performance certified in the database.
Engineering Data Library is a comprehensive guide for pump users, pump manufacturers and engineers in need of references for pump principles, calculations and unit conversions. It covers topics like Net Positive Suction Head, Pump and System Curves, and frictional losses, utilizing standards developed by HI and other reputable sources. The data library will be updated frequently with new information.
Pump Savings Calculator allows a user to calculate Life Cycle Energy and Cost Savings associated with a specific pump installation, incorporating impacts beyond Energy Savings and Pump Cost. Watch the introductory video.
Get clear results to solve your pump and system problems. This free demo of AFT Fathom allows engineers to go beyond hand calculations and spreadsheets to better calculate system pressures, simulate pump performance, and analyze hydraulic behavior. Model both centrifugal and positive displacement pumps in piping systems to quickly compare the impact and tradeoffs for system performance and energy usage.
When looking to optimize pumping system operations, a prescreening tool will assist in identifying pumping issues as part of a comprehensive assessment. This prescreening tool helps identify the highest priority pump improvement opportunities and supports a broad or narrow audit search for improving overall pump efficiency. It also supports engineers in gathering specific data from the field in assessing pump symptoms associated with inefficient energy consumption, high maintenance costs, and other problems and failures. Based on findings, engineers can identify and prioritize pumps for improvement. Optimizing pump systems offers the greatest opportunity in saving energy and improving overall reliability.
MEASUR developed by the DOE consists of the following DOE legacy energy system assessment tools:
The free tool is designed for industrial energy coordinators, plant managers, engineers, and personnel who are interested in improving system efficiency and measuring potential savings opportunities in both dollars and energy savings.
Trench2.0 calculates hydraulic and energy grade line profiles, Froude numbers, and sequent depths for trench-type wet wells with trenches either rectangular or with fillets and/or flow splitters for any flow rate, entrance velocity, curvature at top and bottom of ramp, and size and length of trench.
UnifCrit2.0 solves uniform flow depths (either sub-critical or super-critical) in circular, trapezoidal, and rectangular channels and the relation between size, flow rate, roughness, slope, depth, velocity, and—for round pipes—either with or without Escritt’s modification to improve the Manning formula.
Approach solves super-critical flow in sloping pipes through the hydraulic jump into sub-critical flow for any size of pipe, roughness, slope, flow rate, and desired sequent depth. Escritt’s modification to improve the Manning equation can be used if desired.
