Version 4.1

Version 3.11

PumpSave is a calculation tool running on Microsoft Excel (version 97 or

later) to estimate the energy savings available when using a variable speed AC

drives (ABB frequency converter) compared to other pump control systems.

Comparisons are made with throttling control, ON/OFF control and adjustable

speed control using a hydraulic or other type of slipping drive.

Calculations are based on typical centrifugal pump operating characteristics

and some other assumptions. Consequently, the accuracy of the results is

limited. The accuracy of the results is also affected by the accuracy of the input

data. Results should be used only for estimating purposes. The results of this

program must not be used as the basis for guaranteed energy savings.

Results of calculations can be printed out. When more accurate computing is

needed the DrivePump1.2 PC SW from ABB Drives is recommended.

The tables of ABB Drives have been updated and user manual corrected to the

level of current PumpSave. PumpSave 4.0 did not have a valid user manual.

Most data fields are populated with default values to help users.

Version 3.11 fixes a bug that affected energy calculations in the previous

version. The calculation for ON-OFF control energy usage ignored motor

efficiency given by the user, assuming 100% motor efficiency. This omission

has now been corrected.
