Hydraulic Institute Developes PEI Calculator

Hydraulic Institute Developes PEI Calculator
The DOE Test Procedure, based on the Hydraulic Institute standard for pump efficiency testing (HI 40.6), is a multi-stepped process, and the data required to determine a pump’s PEI, can vary according to the product configuration
To help pump manufacturers understand the complex test procedure and calculate PEI in a consistent manner, HI developed two different PEI Calculator tools with the help of member companies Engineered Software Inc. and Intelliquip LLC. Both tools will help manufacturers determine their pumps’ PEI according to DOE Regulations.  Each tool walks the user through the calculation process according to the pump type and the requisite section of the DOE test procedure.  Data is collected throughout the process and help text is provided to explain the meaning of different values and the testing options.
HI is committed to develop standards, technical resources and programs that benefit the pump manufacturing industry and pump system owner-operators.  These PEI calculators will integrate with the HI Energy Rating Program scheduled for public release in mid-2017.  This new HI Program will list pumps with the HI Energy Rating Label in a searchable database for utilities and end-users seeking efficient pumps that qualify for rebate and incentive programs
