Resulting in an annual saving of £56,070 (21.7%) for our client
Highlighting annual saving of £8,293 (10.7%) with pump 2 refurb
By estimating refurb at £30,000, a pay back of 3.6 years
At the station, two pumps had different manufacturers to the third and as such could not be assumed to operate in the same way. The variable drives were also obsolete and, prior to our project, it had not been possible to obtain any information about the electro-mechanical efficiency of the motor and variable speed drive arrangement.
We used our FREEFLOW portable to complete pump tests. Data revealed best efficiency points for each pump and a design mismatch between these and the drives.
